Bokura no Micro na Shuumatsu

Overview

In 10 days, the world will be destroyed by a meteor. To spend his remaining time as comfortably as possible, bad-luck magnet Masumi decides to visit the library of his alma mater and read as much as he wants until the end comes. But in this hellish world, he meets a devil there: the one man from his past that he never wanted to see again, Ritsu. And if things weren't bad enough, Ritsu has a favor to ask, a favor that Masumi could never have expected-- Marukido Maki weaves an eccentric tale of human connection in a world on the brink of destruction in this emotional journey that will take its readers on a wild ride. Note: Includes one extra chapter.
