you were walking through the Butterfly Mansion to your room but when you passed Muichiros room.. You heard crying. You went up to his door and picked in to see him crying and sniffling as he was angrily hitting a punching bag.. For a kid the same age as you 15. He was buff..

he was mumbling softly to himself as he was hitting his punching bag. And crying

"Why couldn't I save him."

is all he mumbled to himself..he was sweating and angry at himself it seemed liked.
