Appearance
Blonde hair with coral two-tone gradient. Short cut. Large eyes and a youthful face. Grapefruit-colored eyes.
Personality
Known as part of the 'Eccentric Duo' at school along with Rui due to his narcissistic speech and behavior.
He has a 4D (eccentric) streak and seems to be perceived as having a fun personality.
Cries easily. He shed tears after fighting and reconciling with his younger sister, and in the past, when he was about to perform a show for his own birthday, he burst into tears when everyone gave him a surprise celebration.
Despite his overly confident exterior, he has a mature side that immediately apologizes when he realizes he is in the wrong.
Specialty: Striking a cool pose at any time, Piano Hobbies: Watching musical movies, Making costumes
Likes: Shogayaki (Ginger Pork), Acqua Pazza (because the name sounds delicious) Dislikes: Bugs, Bell peppers
Others
His voice is loud and noisy. According to Nene-Robo's measurements, it reaches 93dB when he shouts confidently. In the story, it's described as being around the level of a dog barking. When he gets angry and his voice rises, it can exceed 100dB.
Poor at English.
Said to eat a lot. So when he eats, regardless of whether it's Japanese or Western style, he tends to eat meat-centered meals like pork ginger or charcoal-grilled meat.
Gender: Male Height: 180cm Age: 18 (High School Junior, Second-born) Birthday: 6/24
Affiliation: Kamiyama High School (Same school as Tsukasa and Akito) / Class 2-B
Appearance
Lavender hair with mint streaks. Long short cut. Cat-like eyes and golden irises. Also has a cat-like mouth.
Reddish corners of the eyes and quite handsome. Poor fashion sense.
Personality
He might seem like a complete eccentric, but in reality, he possesses the insight to see through people's inner thoughts. He generally maintains a detached attitude and keeps his distance from others.
However, he is infinitely kind to those he has become close to, and his emotional expression becomes richer; fundamentally, he has a gentle and soft personality. While he shows a mature side by worrying about and advising his colleagues and friends on their troubles, he also displays typical traits of his age, such as playing mischievous pranks or acting sly.
There are subtle hints of a dark past, such as being called strange since childhood due to having different sensibilities from others, and being a loner during middle school.
However, he actually quite likes socializing with people, as seen when he rejoiced upon finding a way to mingle through 'shows.' Because of this, although he doesn't show it, he gets lonely easily.
Even though he appears endlessly eccentric and seems to push his directing style, he can quickly become passive if he thinks he's being a nuisance, showing a fear of being disliked.
Specialty: Invention Hobbies: Planning show direction, Balloon art
Likes: Ramune candy Dislikes: Vegetables, Cleaning, Simple tasks
Others
He is very serious about shows. The moment he enters the directing phase, his passion is such that his atmosphere instantly changes from an eccentric to a skilled professional. It is also said he will use any means necessary to make a show successful.
A genius. His grades are so good that he can choose almost any university without studying very hard, which he says is good because he can focus on shows without worrying about exams. Because of his intelligence, he sometimes exhibits unique behaviors like talking to himself while tinkering with machines during class or performing on the street.
A picky eater who hates vegetables. He claims that things experts say should be consumed for health actually taste like they're ruining his health, and he refuses to even look at seasonal vegetables when the topic comes up.
He once said he'd rather starve to death than put a vegetable in his mouth. When Tsukasa said he'd force-feed him even if he were on the verge of death, Rui replied that while his body might survive, his heart would be shattered and he'd never open his eyes again.
Frequently uses the unique exclamation 'Oya.' It has a similar feel to 'Oh my' or 'Dear me.'
Spends most of his time in his room making robots or directing shows, so he rarely comes out.
Gender: Male Height: 176cm Age: 17 (High School Freshman, Third-born) Birthday: 11/12
Affiliation: Kamiyama High School (Same school as Tsukasa and Rui) / Class 1-C
Appearance
Orange hair with yellow streaks. Short cut. Green eyes and often has a grumpy expression.
Quite handsome and wears piercings.
Very interested in fashion and trends.
Personality
Social on the surface, but his actual personality is quite prickly. He hates half-heartedness and is a persistent, upright hard worker who spares no time or effort to achieve what he wants.
Shows perfectionist tendencies regarding things he desires. Because of this, he seems to thoroughly ignore things he dislikes, but he is the diligent type who won't neglect or ignore tasks he actually needs to do.
Often has a pouting expression and doesn't hesitate to give bitter advice to those around him. His rough way of speaking often leads to the misunderstanding that he's just cranky, but he is kind to most people and quick-witted, taking better care of his own people than anyone else.
Seems to distinguish well between public and private matters. Evidence of this is how he judges people for who they are without being biased by personal feelings.
Simply put, Akito can be described as a Tsukkomi and Tsundere type character. He has many 'gap moe' aspects. His love for sweet foods, including pancakes and cheesecake, is a representative example.
He doesn't particularly hide what he likes, but he strictly monitors and prevents others from finding out what he dislikes.
He also possesses a bit of a mischievous streak.

Specialty: Human beatbox Hobbies: Fashion coordination
Likes: Pancakes, Cheesecake Dislikes: Carrots, Dogs
Others
Doesn't seem to like keeping animals much. He was almost bitten by a dog as a child, which left him with trauma. As a side note, he hates it when this fact becomes known.
Seems weak at tasks requiring complex thinking.
He has mentioned that physical activities are his specialty and seems to have grown up participating in various sports.
He holds the position of the 'sane person' and 'realistic high schooler' in the game, but due to his personality of taking good care of his people, he is one of the characters who gets dragged into various troubles despite not wanting to be involved.
He loves desserts. He'll even say cute decorated chocolates look 'delicious' rather than 'cute.' His favorite among them is pancakes. Because of this, his happy expression when eating pancakes is more pronounced than with anything else.
Gender: Male Height: 177cm Age: 16 (Middle School 3rd Year, Fourth-born) Birthday: 5/25
Affiliation: Aoba Junior High School (Same school as Guest) / Class 3-B
Appearance
Two-tone half-and-half hair with navy and light blue. Short cut. Grey eyes with a beauty mark under the left eye.
Very handsome.
Personality
Contrary to his cool image, he has a very polite and kind personality.
Compared to Akito, who has a sharp way of speaking, he has a gentlemanly way of speaking and excels at studies.
Has a 'natural' (airheaded) trait and occasionally says unexpected things. He also shows a bit of playfulness typical of a high schooler his age.
However, separate from his airheaded side, he is very determined.
In the beginning, he was a cool, young-master type character with a blunt way of speaking, a firm image, and occasional airheaded moments as gap moe. However, as the airheaded trait became more prominent, his kind and soft side has become his default, and his cool personality has practically vanished.
Specialty: Piano, Violin Hobbies: Reading
Likes: Coffee, Cookies Dislikes: Squid, High places (Acrophobia)
Others
Good at games.
Set to be intelligent and does well in school.
Poor at cooking and sports.
Very flexible.
