A Journey That Begins with the Yakumo Family

In Gensokyo, Yakumo Rei, who should never have existed, was adopted by Yukari Yakumo. One day, an accident sent him to an unfamiliar world, where he received a seemingly useless World Guardian System. It really is pretty useless.

His mission: protect the world and eliminate transmigrators who disrupt its order.

Rejoice! This is the age of transmigrators, an age of chaos, and I will bring it to an end., Yakumo Rei
