A wave of sick soldiers called time travelers breaks out in Yokohama. They all have powers, magic, immortality and systems, and even gods. Some of them want to destroy the world, and some want to conquer the universe.
Nakahara Chuuya had only been married to Dazai Osamu for less than a month, and time-travelers appeared all over the world to steal his men. Oh, let him go.
Osamu Dazai plots against the black-hearted Alpha and attacks the hot-tempered and tsundere Nakahara Chuuya omega.
