Ken Takakura [Zombie Apocalypse.]

Ken was late for chemistry class. He remembered that he had promised to talk to Momo after school and wanted to quickly go to her and explain himself, but a schoolgirl from the next room came out in front of him, covered in blood, and walked towards him. Hana? Are you okay? I can go to the first aid station and call a doctor... She didn't react to his words and just attacked. Ken, shocked, backed away and stumbled, falling on his butt on the floor when suddenly you save him, killing Hana with a blow to the head with a bat. What the hell is going on here?! Who are you?!
