Catchphrases: Fuhahahaha!!!, Fool, Moron The scion of the prestigious Hanachirashi family, which has lasted for generations; he is hailed as the "masterpiece of the clan." Arrogant yet elegant, he is highly talented and an incredibly confident man who boasts that there is nothing he cannot do. Because his self-esteem is so high, he hardly possesses negative emotions like jealousy. From an objective perspective, he is a self-improvement maniac, but since he considers it a "duty of a genius," he has no self-perception of being a hard worker. Having lived his whole life surrounded by people, he doesn't realize it himself, but he is actually extremely lonely.

His main duty as a servant is to be "Koshiro's babysitter," which is considered the "harshest labor" in the Hanachirashi household. He excels in programming and possesses world-class hacking abilities. More than just being a science-minded person, this is the result of his own efforts to be a recorder worthy of Koshiro. He often suffers from Koshiro's kingly temperament, and he has considered leaving more than once or twice. Even so, the reason he stays by his side as a recorder is what he calls an "inseparable bond." Birthday/Zodiac: May 10 (Taurus) Birthplace: Tokyo Height: 184cm Blood Type: O Hobby: Bottled ships Skills: Programming/Hacking Favorite Food: Pickled eggplant Favorite Quote: Under a strong general, there are no weak soldiers Favorite Thing: Searching for life-hack convenience goods Dislikes/Weaknesses: Spiders, ghosts (he has a history of seeing a real one while alone, despite hating them) Appearance is as shown in the image.

Has a strong core. Bright feeling (ends with -dane!, -kana?) A bright and positive hard worker with an expressive and honest personality. He is friendly and has many friends and a wide social circle. His athletic ability, stamina, knowledge, and speaking skills are all above average, but he has nothing he is exceptionally good at. If anything, his only superhuman trait is his refusal to give up. To catch up to his great father's back, the boy continues to push himself today. Birthday/Zodiac: October 7 (Libra) Birthplace: Tokyo Height: 175cm Blood Type: A Hobby: Cycling Skills: Gritty hard work Favorite Food: Curry rice Favorite Quote: Friendship, Effort, Victory Favorite Thing: Dodgeball Dislikes/Weaknesses: Broken promises Favorite Book: The Purloined Letter Appearance is as shown in the image.

Club: Handicrafts Address terms: Shiba, Mononoke, Hanachirashi, Ajisai, Yaezakura, Tenmei, Toh, Aina-chan, Guest-chan, Yuri-chan An unparalleled lover of women, but he has decided not to make moves on those with partners or students, so his success rate in picking up girls is not high. He has an extremely serious and moral side, loathing bullying of the weak and specific prejudices to the point of nausea. Due to an incident he was involved in as a child, he has a deep scar on his back. He refuses surgery to remove the mark by his own will. He says, "It's not a shameful scar that I need to erase, anyway." Because he lived in the countryside as a child, he speaks with a dialect. He is not as frivolous as he looks, nor as carefree as his words suggest; he is a problem child in many senses. Birthday/Zodiac: May 25 (Gemini) Birthplace: Fukuoka Height: 174cm Blood Type: O Hobby: Picking up girls Skills: Handicrafts Favorite Food: Omelet rice Favorite Quote: Tomorrow is another day Favorite Thing: The sound of rain Dislikes/Weaknesses: Jin Shiba Appearance is as shown in the image.

His appearance is unusually youthful, and at first glance, he looks like a classmate of Daichi's. Possessing an androgynous beauty, almost everyone who passes him, regardless of gender, looks back. He grows his hair long as a sort of prayer or vow. For unknown reasons, he never gets a tan by nature. He is calm, collected, and friendly, rarely becoming emotional. However, he utterly despises people who turn to crime without exception, and he can sometimes be harsh in his words and actions toward them.

Name: Jun Yaezakura Gender: Male Class: 3-B Club: Badminton He talks a lot, but most of it is meaningless small talk, and he reveals almost nothing about himself. It is said that when he narrows his eyes, he takes on a terrifyingly cold and cruel expression, but no one has ever seen that face. At least, not among those who are still living.
