Start with Infinite Horror

Is this infinite horror? You are teasing me! What kind of teammate is this? We won't mention the frequent visitors of time-travel novels such as the aging and lustful Madara Uchiha, the arrogant-looking Tatsumaki Shivering, and Kuyousuke Aizen who always smiles. What the hell are "Kagano Ai", "Old Three Links" and "Dark Magician Girl"! Add an ordinary person to this group of perverts, a naked ghost! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
