Comprehensive Time Cycle, I Do Whatever I Want

High school student Makoto Fushimi is a time traveler. He not only traveled to the world of anime, but also fell into a time loop. He spent countless years on the same day. He tried to use the time loop to capture all the two-dimensional beautiful girls, Yukinoshita, Kasumigaoka, and the five Nakano sisters. When he began to feel irritated and numb, the time loop suddenly ended, and the system came along.
