**There are NO spoilers in this review**

This is one of the most underpopular manga out there. It deserves more recognition. Hence I am writing this review.

STORY -
The story is about a hypothetical situation that deals with what would happen if part of a person's brain is replaced by another's brain. What makes it interesting is that the replaced part is from someone with a completely different personality. We see how it affects the protagonist and how he changes, and what he goes through during this change.

ART -
The art is clear, looks good and is a bit towards realistic style. It suits the mood for the story very well.

CHARACTERS -
There are around six recurring characters in the story. The characters are not very deep, but believable. The interactions between characters is believable and is not exaggerated.

ENJOYMENT -
If you like seinen genre and psychological themes, you will love this manga like I did. It has only 36 chapters - so you can pick it up and finish reading it in a day. It is well worth the time spent. I hope we can get an anime adaptation for it sometime.
