Ultra: Nagi Saijo

When the time-traveler becomes Saijo Nagi, something is wrong. He is obviously not an orphan nor a person with great hatred. Why should he be allowed to time-travel? Why! ! ! ! She refused to accept it, he was still a "child", why should he be allowed to travel through time and there was a Sabi villain... Wait, besides me, there seems to be a time traveler and a system too! ! ! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
