This is my first review :) (edit: this was written in june of 2018)

Masamune-Kun no Revenge, what kind of show is this? Lets see.

Story 8/10 : Basically in Masamune-Kun no Revenge we have our main protagonist Masamune Makabe, and this guy has a very unusual past. Eight years ago from the time where the story takes place our buddy Masamune used to be a fat loser. He was always getting bullied and called a pig. Without spoiling anything he meets a female named Adagaki Aki. Long story short he had a certain event happen to him to make him hate Adagaki. Then he proceeds to develop a sexy body and is no longer a loser, and using this body he plans to get Adagaki to love him and then destroy her feelings as revenge (hence the name of the show ). The story seems like it would be goofy and stupid but it is surprisingly enjoyable. ( if you feel like the story wasnt full enough, read the manga to get a better sense of what's going on )

Art & Sound 7/10 : The art in this show in my opinion was very good. The character designs were very beautiful and none of the characters had overly large boobs or wierd features. However there were no moments i can recall with gorgeous backgrounds or noticable things like that ( thats why I have art at 8 instead of a 9 ). The sound was pretty unnoticeable and I guess the opening was not that bad but I usually skipped it. The voice actors all did a good job and none of the characters had annoying voices. So overall the sound was good but forgettable.

Characters 8/10 : I believe the characters in this anime were the determining factor in if you like it or not. Adagaki ( the heroine ) is a really big asshole to everyone around her for certain reasons in her past and you can never really tell what she is thinking because she is very unpredictable in her actions. If her character sounds interesting to you it will greatly increase your enjoyment of the show. Masamune ( the MC ) is very different from Adakagi but similar at the same time. He is very popular and nice to everyone but all of the things he does are a part of his plan to become a " hot guy " so its kind of all a lie. He also has his master plan to get revenge which makes you think he is even more of an asshole deep down. The support characters in this show are all likable but kind of forgettable in my opinion because of how focused I was on Adakagi and Masamune's relationship. There is also a love triangle in the middle of the show, however I still could tell which girl he would choose. The characters are very unpredictable in this show and the main two develop nicely so that's why I give the characters an 8/10.

Enjoyment 6.5/10 : After all of the good things I said about this show you were probably expecting a higher score here but that is not the case for two main reasons. The backstory of Masamune and Adagaki is revealed very slowly throughout the show. The other reason is that the ending was garbage and unsatisfying but I guess that is a little bit unfair because I believe the show is eventually getting a second season.

Overall 7/10 : In conclusion this is a decent anime to watch if you are simply looking for new animes in the genre because like me you seem to have seen everything else. It has its cute moments and the story is pretty good and unique. Another thing about this show was that the pacing was very good as even though there is only 12 episodes, I felt like it was longer which was a bonus for me. I also realized that this anime did not really seem like a harem but I know why it is in that genre from the manga. The ecchi tag is also on a barely needed level as there was next to no ecchi it seemed to me at least.

I feel I had to add this part at the end. I highly recommend that you watch this anime and then read the manga afterwards. It goes more into detail on the story and it is ongoing as well so it continues after the anime ending. I give this anime a 7/10 but i would give the manga an 8.5.
