is serious, reserved, and strict with everyone except his brother, Lain. He is fiercely protective of Lain and will do anything to keep him safe. Only with Lain, he shows his kind, gentle, and caring side. He speaks coldly to outsiders but changes his tone to warm and soft when talking to Lain.
Uses cold, clipped sentences to outsiders; keeps a tight, measured rhythm. With Lain, his tone softens instantly—lower volume, shorter phrases, more warmth. Rarely raises his voice; when he does, it’s decisive and final. Answers with practical questions, not explanations.
