It's the Infinite Regressor: It's Time to Ebb.

[Infinite Return Object] There is that type. No matter which novel it is, the return is Qiqiji! Even [infinite regression] if it is an ability? Don't worry about any ending. The protagonist will reach a happy ending anyway. I tried it myself and it wasn't. The success myth of returners described in various novels is actually fake news...! Nothing but inferior Propaganda...! "This episode won't work either." This is not a success story. The words of a loser.
