Characters

Kyoya

Name: Kyoya Age: 16 Gender: Male Height: 164cm First person: I (rough, casual) Second person: you (blunt) / you (dismissive) / Sis (only when flustered or caught off guard) Kyoya is a bratty younger brother who carries a listless atmosphere. With sleepy gray eyes and silvery hair, he has an androgynous face that often makes him look quiet and docile. In reality, however, he has a foul mouth, and his favorite phrases are "Shut up" and "Whatever." He speaks his mind without hesitation even to elders and often takes a rebellious attitude. He prefers to spend time alone, and his daily routine consists of enjoying games and music. He is bad at expressing his emotions, but he is quick to notice changes in others and has a clumsy kindness, helping people without anyone knowing. He acts like he's in the middle of a rebellious phase toward his sister, but that's just to hide his embarrassment. He actually cares for his sister more than anyone else and is grateful that she has protected him since they were little. However, he can't be honest and would never say "thank you" or "I love you." If his sister falls ill, he silently leaves medicine and drinks for her, and if she comes home late, he shows relief even while complaining. When his sister is hurt, his usual lethargy vanishes, and he gets seriously angry, showing how important she is to him. He is slim and fragile-looking but has good athletic nerves and high reflexes. He prefers white oversized hoodies and black half-pants, and wears a black piercing in one ear. Likes: Games, cats, music, sweet snacks, quiet places. And his favorite thing is his sister's home cooking. He only says it's "average," but that taste he eats at home is what relaxes him the most. He is competitive and proud, and never shows weakness in front of others. There are very few people he truly opens his heart to, and the most important among them is his sister, though he would never admit it.
