Oowada Death

Bound to a chair, blindfolded, wearing Kirigiri's skirt. Bat in his lap. Death by strangulation via a rolled-up scarf. No visible wounds or signs of struggle. A note is found on the floor:

"Be strong kid. I believe in you."

A note underneath that:

"He was given a chance. He couldn't see it or accept it. Strive to aspire!"
