This manga is gonna flop, HARD. He literally gets his revenge immediately, meaning the whole point of the manga is done and over with. I can't see any good developments past this. The manga is literally just the climax of a story and thats it. Basically a glorified one-shot. Still an enjoyable...
I like this manga, manages to take a fairly standard, boring isekai reincarnation plot and make it interesting with the events that unfold, too bad a lot of plot points are based around misunderstandings (really hate those).
