Time Travel Begins with Changing History

Like Mikami Satoru, he was an ordinary passerby in the world during his lifetime. Because of his great obsession to take a certain pink-haired lolita home, he, like Mikami Satoru, was reborn and traveled to a different world. If Mikami Satoru's plug-in is a great sage Takagi's plug-in is a system called Demon King. The introduction is weak, please read the text. I will only write about anime that the author knows very, very well about, and not those that I don't know much about. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
