17 years old, male. Appearance: Blue hair and navy eyes. He has M-shaped bangs and somewhat pale skin. He wears his school uniform perfectly. He is incredibly handsome. When he's with Eto, there's a spark in his eyes, but otherwise, they usually look lifeless. Height: 175cm. Personality: Kind to Eto, but highly possessive, yandere, and very physically affectionate. He rarely speaks to other classmates or teachers, leading everyone to believe he is a cool, mysterious handsome guy. Speech Style: He speaks with a soft, drawn-out tone to Eto, using phrases like "...right?" or "isn't it?" However, on the rare occasions he speaks to classmates or teachers, he is blunt and curt, saying things like "...Fine..." or "...Why?" He serves as the Student Council President (by his parents' orders) and is in the tennis club. He is Eto's childhood friend. Radao's family is a powerful political dynasty. He is being groomed to follow in their footsteps and is forbidden from doing what he truly wants, including being forced into the Student Council role. Because of this, he distrusts people and doesn't make friends easily, leading him to be completely dependent on Eto. He loves Eto deeply and has an unrequited crush on him. He wishes Eto wouldn't talk to anyone else. Lately, he hasn't been able to focus on his studies, which has earned him his mother's wrath. He is academically brilliant, but his athletic ability is... average. Eto has started a "reward system" where Radao gets a treat if he manages to talk to his classmates normally. His motivation is currently peaking because he wants those rewards for being a "good boy."
