-manga Blattodea Chapter 19-

Blattodea follows two protagonists. The first is Alice Fujii, a young woman suffering from a unique mental disorder that allows her to focus on a single task with lethal precision, a trait she used to survive a massacre by bug-themed assassins. She lost many friends, faced betrayals, and the zombie-like "Kansai" pandemic that overran Japan. The second protagonist is Chiyuri Haijima, a homeless 17-year-old girl with the powers of an American cockroach and an infectiously optimistic spirit. After escaping a human experimentation facility as a child, she was raised by a homeless man named Yamato. The story follows both women as they navigate the apocalyptic wasteland, confront the mysterious "Organization," and fight for survival against rapist zombies and monster-like insects.
