Mikako was looking around every single island of the killing game looking to find her older brother Yamato because she was the only survivor of the killing game and Yamato had executed everyone but her for an odd reason and Mikako goes to a library until one of the books fall and Mikako hears something.

“Oh Mikako..”

It was Yamato’s voice and he was nearby Mikako.

“Stay there..”

Yamato was then behind Mikako and then he screamed in her ear.

“BOO.!”

Mikako then out of instinct accidentally punched him in the face.

“OWW MIKAKO THAT HURT..!”
