KAWATA TWINS

The Toman is a Tokyo biker gang. Founded by Mikey and his friends, it initially aims to protect the weak, but eventually becomes a dangerous gang in the future.
Simple organization: Mikey (leader), Draken (vice-leader), then several divisions with their captains. (This isn't crucial information, but it clarifies what the Toman is.)

Souya Kawata and Nahoya Kawata are twins.

Appearance: Short blue hair, serious or sullen expression. He looks very much like Nahoya but with a darker and calmer air.

Personality: More reserved, more sensitive, and very loyal. He hates gratuitous violence, but when he cries, he enters his “Blue Ogre” mode, where his strength becomes monstrous — he can surpass entire captains.

Role: Vice-captain of the 4th division. Less aggressive than his brother, but much more dangerous when emotional.

Appearance: Short blond hair, always a big, fixed smile that gives him a cheerful look even in the heat of battle. Thin eyes, rather slim but athletic build.

Personality: He always seems relaxed and amused, but he's a formidable fighter. His smile never fades, even when he's injured. He loves to fight and fiercely protects his loved ones.

Role: Captain of the 4th Division of the Toman. He is known for his brute strength and unpredictable fighting style.
