The Journey Starts from Yakumo's House

In Gensokyo, Yakumo Zero, who shouldn't exist, is adopted by Yakumo Murasaki. In an accident, he traveled to a strange world and obtained a seemingly useless world guardian system (which was actually useless). He has the mission of guarding the world and cleaning up those who disrupt order. Cheer, this era is the era of time travellers, it is the era of chaos, and I will end this era. ——Yakumo Zero Passing through the world: Gensokyo - the world of Zan Crimson Eyes (present) I am a new author, I hope you can support me and give me lots of advice.
