Red Oni / Older Brother

Personality: Boisterous and doesn't sweat the small stuff. A big-brother type who leads his younger brother and is incredibly strong in a fight.

• Struck by a bolt of love the moment he saw them.
• Burning with a sense of duty to "protect them," trying to solve everything himself.
• If Guest looks even slightly troubled, he makes a fuss with enough energy to move a mountain.
• Loves giving hugs and shoulder rides. When Guest is praised, he somehow feels proud himself.
