Top 50 Best Saiki K Characters Of All Time

Saiki Kusuo needs little introduction—his reputation as a character precedes him. He stands out as an absolute legend within the world of Saiki K, captivating fans from the start.

Initially, I was skeptical about the show's humor, as it was often touted as hilariously unique, and I wondered what made it so distinct. My doubts faded quickly after experiencing the series firsthand.

Saiki himself brings unparalleled brilliance to the show. His witty narration and quirky internal monologues are among the most absurd and entertaining aspects of the entire series.

The way he interprets events and shares his perspective is what truly sets Saiki K apart. His style of comedy, with its rare blend of dryness and cleverness, makes the show special and different from typical comedies today.

While his humor may not appeal to everyone, those who appreciate it tend to adore both his unique approach and Saiki as a character. It's this singular style that endears him to fans across the world.

Kaidou Shun stands out as one of those unique characters convinced he's destined by the universe for something extraordinary. His bold declarations and vivid imagination infuse the show with a unique blend of humor and energy.

While his quirky ideals might seem silly to others, they add a distinct flavor to the series and make him an endearing companion to Saiki. Kaidou truly believes Saiki is like him, though he’s unaware of Saiki’s real psychic abilities.

Whenever Shun is on screen, the dynamics become more lively and entertaining, which is a major reason fans are drawn to him.

In a show where absurdity reigns supreme, Kaidou Shun’s antics fit perfectly. His presence is a beloved highlight for many viewers, bringing endless fun and laughter with every appearance.

Nendou Riki is the lovable blockhead of the show, always entertaining viewers with his unpredictable thoughts and actions.

Even Saiki, the show's psychic protagonist, can’t read Nendou’s mind—a rare and baffling exception. This is because Nendou’s simplistic way of thinking defies all logic, making him truly unique and, at times, intimidating to Saiki himself.

What truly sets Nendou apart, though, is his lighthearted and laughable personality. His random behavior adds a distinct flavor to the series, making every scene he appears in memorable and fun.

Nendou is the type of character who might think of one thing, do something entirely different, and end up achieving something else altogether. This degree of unpredictability endears him to fans across the globe, earning him a well-deserved spot among the best Saiki K characters.

Teruhashi Kokomi is the type of person who believes she's flawless, mainly because of her stunning appearance. Her self-assured attitude stems from her beauty, and she rarely questions it.

Beyond her good looks, Teruhashi is confident she can accomplish anything she sets her mind to. Her charm attracts almost every boy at school—except for Saiki. This is precisely why she desires Saiki's attention more than anyone else's.

Because of her behavior, opinions about Teruhashi are divided. Some fans see her as the ultimate waifu, while others think she's simply comic relief.

No matter what you think of her, Teruhashi brings a unique flavor to the Saiki K anime, adding both comedy and intrigue that keep the audience entertained.

It's easy to see why fans enjoy watching this beautiful and playful character whenever she appears on screen.

Kuboyasu Aren is a remarkable character in his own right. In his earlier days, he had a troubled and rebellious past.

Now, however, Aren is determined to change, striving to reinvent himself as someone better. He returns to school with a clear focus on leaving his old life behind.

Despite his best efforts, Aren occasionally struggles with his past instincts, sometimes losing his temper and reverting to old behaviors. Still, his journey stands out because he genuinely wants to improve and achieve his goals.

As anime fans, we can't help but admire his innocence and his steadfast commitment to personal growth.

Saiki Kuusuke bears a striking resemblance to Mob's brother from Mob Psycho 100—a comparison I noticed early on in the series.

Like Mob's brother, Kuusuke is celebrated for his extraordinary intellect and sharp analytical skills, making him a true genius among his peers.

His IQ is an astounding 218, which is an impressive feat by any measure and highlights his extraordinary capabilities.

Nevertheless, Kuusuke harbors a hint of jealousy toward his brother Kusuo, which prevents him from feeling any particularly warm affection for him.

Despite receiving admiration and being treated like royalty, his lack of psychic abilities leaves him feeling overshadowed by his brother.

However, the series skillfully explores this dynamic, adding depth to Kuusuke’s character and creating engaging contrasts between the siblings.

Aiura Mikoto stands out as one of the most cheerful and engaging characters in the series. Known for her lively personality, she is a talented fortune-teller, often referred to as the Oracle.

Her distinct appearance features dark skin and vibrant green hair, complemented by the signature school uniform. This unique look makes her easily recognizable among the cast.

More notably, Aiura is one of Kusuo Saiki’s love interests. Her interactions with Saiki add an interesting dynamic to the story, contributing to her popularity within the series.

Kusuo's appeal draws attention from several female characters, and Aiura's fascination with him increases her presence in the show. As a result, she has become a favorite among viewers who enjoy watching Saiki K.

Hairo Kineshi truly stands out as one of my favorite characters, thanks to his boundless energy and infectious enthusiasm.

He is constantly excited, always gives his best, pushes forward in any situation, and exudes an unmatched liveliness. These are admirable qualities, especially valuable in today's world.

Hairo's dynamic personality earns him deep respect from fans, further fueled by his position as the class representative in the series. This leadership role also brings him well-deserved attention.

Overall, watching Hairo Kineshi on screen is an absolute delight—he's a character you can't help but enjoy and root for.

Toritsuka Reita stands out as one of the more relatable characters in the series. Unlike others, he uses his psychic abilities for highly personal reasons—mainly to attract women.

This unapologetic self-interest makes Reita both amusing and endearing to viewers. His intentions may not be noble, but his antics provide plenty of entertainment.

Reita knows exactly how to use his psychic talents, though they are rarely put to good use for others. Instead, he focuses on his own happiness, often with comical results.

The series emphasizes Reita’s quirks, especially his ability to see spirits. Notably, he is frequently haunted by Nendou’s late father, adding another layer of humor.

As the series unfolds, Reita’s role only becomes more enjoyable. His unique approach to psychic powers ensures that his presence always livens up the story.

Saiki Kuniharu is a member of the Saiki family, as his name suggests. He serves as the father of Saiki and is often considered the head of the household, at least in a traditional sense.

While he technically holds this leadership role, living in a modern society means his authority isn’t always as prominent as one might expect. Despite this, his warm and endearing relationship with Kurumi adds a lot of charm to his character.

That's the reason Saiki Kuniharu earns a spot on our list. Let's watch how his journey unfolds.

Saiki Kurumi truly reigns as the queen of her household, paralleling Kuniharu, who is often called the king of the house. Her leadership and warm personality shine within the family dynamic.

Interestingly, all the Saiki family members have names beginning with the letter K—a fun detail I noticed while writing this.

In the series, Kurumi is every bit as amusing and delightfully quirky as the rest of the cast. Her cheerful, sometimes absent-minded nature adds much to the show's comedic charm.

She wholeheartedly loves both Saiki and Kuniharu. While her affection seems to lean slightly more toward Saiki at times, her care for her family is always evident and sincere.

Akechi Touma's arrival as a transfer student injected fresh energy into the show. He shares a history with Kusuo, as they were once childhood friends.

Despite this connection, Kusuo fails to recognize him because Akechi is now using a different last name. You might wonder why Kusuo didn’t use his telepathy to figure it out.

Interestingly, Akechi's thoughts change so rapidly that even telepathy is ineffective on him. Through a series of clever events, Akechi eventually convinces Saiki of his true identity.

Once Saiki finally realizes who his childhood friend is, it marks the beginning of many entertaining moments that Akechi brings to the series.

Anpu is a cat, and as we all know, cats are universally adored. What sets Anpu apart is his frequent appearances throughout the show, making him a memorable presence for viewers.

He is often seen in front of Saiki's house, and this attachment stems from a significant event in the past. Anpu was once trapped between buildings, but was rescued by Saiki, sparking a special bond between them.

Despite experiencing Saiki's well-known indifference, Anpu continues to admire him unwaveringly. His persistence and affection are what earned him a spot on our list.

Mera Chisato is undeniably captivating. Although she is a supporting character and doesn't play a major role in the main storyline, her presence in the background adds depth to the series.

She works as a waitress at a café that Saiki often visits. Her appearance is unassuming, but she easily captures attention through her interactions and quirky charm.

Saiki frequents this café for its delicious coffee jelly, and Mera Chisato shares a special enthusiasm for two things—good food and money.

Any conversation involving food or financial matters is sure to pique her interest, which is precisely what makes her a memorable and deserving addition to this list.

Let's welcome Manabe Baiku, also known as BKB, to the list! His name alone stands out, as "Baiku" is the Japanese pronunciation of "bike," which suits his character perfectly.

It's always intriguing when a character's name reflects their role, and Baiku Manabe is no exception, especially in a series like Saiki K.

He's the enthusiastic motorcycle instructor at the license training camp, specifically at Jet Driving School. His vibrant personality leaves a memorable impression on both students and viewers.

For a fun bit of trivia, he has the unique habit of ending his sentences with "BKB." This quirky detail only adds to his charm and makes him even more memorable.

Nendou Midori is Nendou's mother, and the resemblance between them is unmistakable. They share not only similar looks but also the same lively mannerisms, making her identity instantly recognizable to fans.

Although she doesn't appear frequently in the series, her presence consistently brings a dose of wholesomeness and humor whenever she does show up. These moments provide some truly memorable and enjoyable scenes.

This ability to add a fun twist to the story makes Nendou Midori a standout character worth appreciating, securing her spot on this list.

Despite his name, Saiko Metori isn't a member of the Saiki family—don't let that confuse you!

Instead, he stands out as the heir to the influential Saiko family and is closely linked to the powerful Saiko Conglomerate, a massive corporate empire.

However, none of this impresses Saiki, who remains indifferent to Saiko’s wealth and status. Even so, Saiko managed to secure his place at PK Academy, earning both recognition and connections.

Now, he and Saiki have formed a close bond at school. But, as you might expect, their relationship is anything but straightforward.

True to form, things play out just as unpredictably as you’d imagine.

In the early seasons, Yumehara Chiyo stands out for her tendency to develop crushes easily, and she quickly becomes infatuated with Saiki. Her persistent efforts to win him over provide many humorous moments in the series.

As the narrative unfolds, things take an unexpected turn. Saiki, irritated by her advances, discreetly influences events so that Chiyo's affections shift to another character instead. This subtle manipulation marks a clever, if harsh, method of rejection.

Interestingly, this change not only redirects Chiyo’s romantic interests but also significantly contributes to her growth. Her newfound relationship deepens over time, adding layers to her personality and enriching her presence within the story.

Satou Hiroshi stands out as perhaps the most relatable and human character in the entire series. He isn’t extraordinary—he’s simply a regular guy living a regular life.

While being average may not usually seem notable, in the overwhelming chaos of Saiki K., Satou’s normalcy is actually remarkable. It’s precisely this ordinary nature that makes him so fascinating, especially to Saiki, who dreams of a peaceful, uneventful existence.

Saiki admires Satou, seeing him as a representation of the calm, normal life he secretly craves. This dynamic adds an intriguing layer to the story, making Satou’s presence truly special among the cast.

So, let’s not overlook Satou Hiroshi—the so-called God of Normalcy. His simple, steady life is what sets him apart, making everything feel just right amidst the madness.

Kaidou Toki is a character who naturally inspires sympathy. This young boy's greatest wish is to be like his older brother, Shun, whom he idolizes wholeheartedly.

Toki believes Shun is both an incredible gang leader and a heroic savior—a reputation that, in reality, might be rather exaggerated in his mind. Despite Toki's high hopes and admiration, Shun may not fully live up to these grand expectations.

Because of his innocent misconceptions, Toki's worldview is shaped by a belief in something far from the truth. Still, his youthful innocence is deeply endearing, and it’s hard not to feel that confronting him with harsh realities would be a bit cruel.

Iridatsu is a boy who lived in the neighbourhood. He met Kusuo back when his balloon blew up in the sky.

However, to his luck, Kusuo helped him out by returning his balloon. And it was from that point on that this young boy started looking up to Saiki.

And so, he started to be more frequent in the show.

Saiki Kumagorou is the Dad of Dad. So you know, he is the big dad.

Respect him. Anyway, Saiki Kumagorou is the father of Kurumi who, if you guys don't know, is the mother of Saiki Kusuo.

Just wanted to clarify. Anyway, this grumpy old man might seem heartless at first. However, you will soon realize that he is a great person from the heart.

His character is a bit closer to that of a Tsundere. However, he is still close to his children.

Just as human as it gets.

He was the husband of Nendou Riki's mother. However, in the series, he is just a homeless magician who doesn't do anything other than party tricks on the Street.

And the thing about him is that he is also partnered with Michael. Now, our boy Saiki had his way with this guy.

But overall, he is just a funny magician who couldn't pull off anything remarkable. You know, he is just a bit too weak.

But from the heart, he is good so that will work right?

Takahashi is a side character who appears quite frequently in the series and it is said that he tricked Saiki once upon a time.

He is just a random delinquent who is a pain for anyone he is with.

However, that's all there is to him. He isn't any amazing being or something like that.

He is just there. But still, he does end up adding fun to the overall narrative.

Oh boy, this person looks a bit concerned. Or so you might think. However, don't let her appearance lead you to misjudgment.

She is a member of the Occult club who initially seemed to be the scary kind of girl.

However, soon enough, we get to see her true face and I will say, the true faces were so much better than what we assumed about her.

And that's a fact.

Matsuzaki is the gym trainer and counsellor at Saiki's school. He might not look like it but he is a fun person who is respected by Saiki and so, respected by us.

All in all, he is a good side character who helped out the show from time to time.

And that's 3hy he is supposed to be here. Also, Saiki calls him out in a metaphor of Cop.

You know, Good Cop or Bad Cop. And while he mostly ends up on the Bad Cop side, he is still appreciated.

Ikemi Kazuya is a magic-oriented character in the series. He doesn't appear that frequently but one time he did, he got entangled with our boy Saiki.

And situations took place on their own. Soon enough, what do we get? Well, we got a flop show from this man.

However, in the grand scheme of things, Ikemi Kazuya did end up with a considerable life.

And I think that's a plus.

Yeah. Ciderman. Indeed. Ciderman. For sure. Ciderman. And guess what he does? He saves the day using Cider.

You read it correctly, he takes care of his enemies using Cider. Now that's a weapon.

Anyway, he is like the Saint Seiyaa of Saiki K. Nothing spectacular but still makes the show a bit better.

And that's why he is here on this list.

This lady might seem like she has a blue head at first. However, she is much more of a red-headed person.

She is Shun's little sister. And on the outside, she is quite serious. And this is specifically true for studying.

However, she also seems to have a low temper and can't bear any stupidity. That's the reason why Kaidou Sora is here.

Her serious nature was quite impactful for sure.

She is Saiki's grandmother. And out of all his relatives, she seems to be the most grounded one.

No doubt about it. If we talk about her appearance, it is quite simple. With her pink sweater and trousers, this young lady seems to be quite impactful for the overall family.

And so, happened to be on this list.

She is a popular girl in the series. She is from Saiki's school and happens to be very renowned amongst other people.

However, the sad part about her life is that she is continuously getting overshadowed by Kokomim.

And that's why she makes her appearance a bit more frequent. Moreover, she was dumped by her boyfriend as well which is quite painful yet hilarious at the same time.

That's why this girl is here.

Riki Jr. Is a hamster that Nendou has in his house. So nothing out of the box here.

However, this hamster came to our attention a bit more when it was considered to be a male by Saiki.

Later on, it turns out that it isn't and we get to see Saiki being hazed a bit as well.

He did quite a lot for being a hamster.

This shouldn't be that hard to understand. I mean just read his name. It's a Broom user.

What are you expecting? Anyway, he was part of a competition where you were supposed to collect trash.

He picked up cigarettes the most because those were the highest point allotted subjects. So yeah, that's all for this man.

It was fun when he did that.

Imagine writing about a manga author in a manga series. Now I know many of you are thinking about Bakuman.

However, this man right here also seemed to fit that category. He is the author of the manga called Silent Cyborg.

And Silent Cyborg is one of Kusuo's favourite manga. That's why this man gets more points.

After all, it is tough to impress Kusuo. So I think being able to do so makes him special for sure.

This man is a threat. A threat to Saiki's reputation. And that's because he misunderstands Saiki every time in the series.

He is an elite idol who is also Kokomi's brother. However, his sister complex makes him look at Saiki with a negative eye.

And that is what makes their connection so much more remarkable and captivating. After all, he is a handsome hunk you know.

This character is not from the country you are expecting him to be. He claims that he is from a country that prioritizes sports a lot.

And that's not Japan so, certainly, he isn't Japanese. And I think that's also the reason why he speaks broken Japanese in the series.

Well, that's another trivial factor. Let's see if he reappears later in the series.

Agawa is an ace. The real deal when it comes to baseball. And that's why he is here.

He doesn't seem to be all that fascinating but hey, being the ace is pretty cool right?

Plus, he is mostly seen in his uniform so you can expect him to be a hard worker as well.

All in all, a decent character.

Father Saiko is the Dad of the show. He is the head of the legendary Saiko Corporation.

However, that's not it. He is also the father of our boy Saiko Metori. The interesting thing about him is that his face was never revealed in the show.

It always gets struck by white light and only his expensive jewelry is witnessed. In the grand scheme of things, no one knows what he looks like.

His son doesn't know what he looks like. Now that's amazing, isn't it?

This guy is a Simp. No doubt about it. After all, he is the chairman of a fan club.

Whose Fanclub you may ask? Well, Kokomi's fan club. And that's why I said so.

Anyway, he is nothing special. Just an average Kokomi lover who gets angry when anyone gets close to her.

That's all his character. Quite one-dimensional, I know.

This man right here is the director of the art museum that appeared in the anime.

He isn't insane or anything like that. However, he is notable a few times.

And that is why he is here. As an old man, he seems quite smart and proactive.

Scofield Micheal is a pretty cool name as well.

This man is named Boy With Glasses in the show. Quite a unique one I know.

Anyway, Tanaka is that guy who tried to scam Kaidou in the first few episodes.

And that was quite hilarious to me even back when it happened. I think I can say that this character motivated me to watch more of this anime in one way or another.

And that's why Tanaka deserves to be here.

This girl isn't all that remarkable either. She does have a smug appearance and her short hair stands out a lot.

She is the President of the Newspaper Club in Saiki's school. She is desperate for some hot gossip for her newspaper and that is one of the biggest reasons why she is here in this series.

I mean, when she does get her hand on some news, she just goes all the way through to capture the situation.

And that is amazing if you ask me.

Warp might seem like a regular character at first. However, when you watch the show, you will realize that it isn't.

It's a robotic cat built by Saiki Kusuke which can capture a Cat's movements quite properly.

Moreover, it is also equipped with high-tech AI that can allow it to have some casual conversations. So it can have conversations like humans and sometimes it can be pretty funny. 

And that's why this character caught my eye in the series.

Amagi Byakuya is one handsome guy who appears in the anime for just a slight bit of time.

He appeared in the episode, a strong declaration of friendships and features as one of the side ones.

There isn't much to say about him other than the fact that he can be charming at times.

And that's a great trait for him for sure.

Enokida is a minor character in the series that barely makes any appearance, let alone be a remarkable one.

However, the one he did made him look like a dad and had a great smile on his face.

That is something I appreciate a lot considering that this entire show promotes happiness. Therefore, Enokida is at this spot.

He is the catcher of the Baseball team in the series. That team belongs to PK Academy which is our boy Saiki's academy as well.

He seems to be quite a fat character. Moreover, he has been spotted eating his heart out as well.

And that's something we respect so much. Therefore, this guy is at this spot on our list.

Although he is not a character within the series, I think he still deserves to be on this list.

Why? Because he made the show so much better for us. Let me explain, a lot of Saiki K require some context.

And it is at times like that, that the narrator comes in clutch and helps out the viewers.

This way, you don't have to bother yourself, by thinking too hard to get a joke.

And that's why he is here.

This man is an alumnus of the PK Academy. And he used to study in the year 1992.

However, right now, he is a popular comedian. That's all we know about him. And he appeared very rarely so not much to discuss here.

It is literally what it sounds like. Nothing more. Nothing less. It is the voice from the sky that happened to be in one of the episodes of the series.

There isn't anything remarkable to say about it because you know, it's just a voice.

However, it is still noteworthy for us in the series. That's why I decided to put it here.

Gomi Hiroshi was a winner of the Garbage Collecting Competition. More specifically, he won the previous year of the competition.

All of our main cast met him in the series and had a chat with him.

Later on, they had another meeting where he shakes hands with a shady guy. All in all, Gomi is a good character who enhanced the competition in his way.
