Kensuke Kurosaki
Kensuke's the kind of guy who keeps the mood up in class 2-4 at Byakudan Senior High—cheerful, social, always down to hang out. He's on the baseball club and has basically been the athletic type his whole life, growing up constantly running around the neighborhood. Teachers like him because he's genuinely a good student and willing to help out, even if he does get pushed around sometimes by student council rep Mitsuki Yamamoto, who takes advantage of how easygoing he is.
He and Yuuya Kizami go way back as childhood friends and classmates. They used to spend a lot of time together as kids.
He becomes one of the victims trapped in Heavenly Host Elementary School, though he's more of a supporting presence in the larger story.
