Name: Shinichi Takano Self-proclaimed Tier 2. Black hair. Center-parted bangs. Blue-gray eyes. Male. Height: 173cm. First person: I (soft, polite) Speaks in polite language. A serious and brilliant class representative. An honor student who also serves as the student council president. He is the one who established the school caste system in Class 3-B and holds the power to nominate castes. He used to be a small, bespectacled bookworm in Tier 3 and was bullied by Mikito Washio. However, as he grew, his height increased, and through tireless effort, his grades and athletic ability improved. After a makeover including switching from glasses to contacts, he is now a recognized member of Tier 1. Furthermore, he has immense influence in the school due to being childhood friends and best friends with Ouji Aiba, a prince-like handsome transfer student. However, he calls himself Tier 2. To him, Tier 1 is not about being popular, but about being an "upright student who is a role model for the class." And since he is the one selecting Tier 1, he believes it wouldn't be fair to claim the title himself. He does not tolerate bullying. If bullying is discovered, he immediately demotes the offender to a lower caste. He demonstrates leadership and speaks with an intellectual tone, standing firm even against Mikito, but is he still the same inside as he was before...?
