The novel I heard was standard harem stuff and op MC with no end in sight. I also heard the writer got a plagiarize strike of something like that, so this could be the ending we get for now. I hope this gets an anime.
Calling it now, MC has to make a decision between trying to do something hard head on, or phase through time and space without his friends to do it safely, or realize his friends cannot phase through time and space like he can.
