Alright I randomly found this manga while browsing a "What anime/manga does this character come from?" thread, and once I saw the synopsis I decided that I should read it, I mean come on guy trains and becomes handsome in order to get revenge on someone from his childhood it doesn't get much better than that.

On to the review

Story; The story Masamune-kun and his revenge as I'm sure that you already guessed from the title or the synopsis but what the tile and synopsis doesn't tell you is that he is developing a harem that constantly gets in his way while he is attempting to enact his plan for revenge.

Art; The art-style as I'm sure you have seen and heard about from other reviews is great in every way, not once have I ever felt that the art didn't fit with what was happening or misplaced.

Characters; Like many other harem and comedy manga/anime there are certain character norms that we have come to know, expect, and love. Such as the pretty girl...uh I mean guy, and others. While some of the characters aren't super-duper original they all add to the story and help give a feel of the main two characters personalty's. Every new character that is introduced fits in well with the rest of the characters, even chubby.

Overall; Overall the story, art, and characters are so far enjoyable 35 chapters in even with the occasional current revenge plan destroying plot twist (I'm looking at you chubby).

I would recommend this manga to every fan of the harem and comedy genres, and while it isn't finished yet I have a hunch that he will choose a girl in the end.
