Heads is the first manga that I have read from Keigo Higashino. Without putting too much spoilers, here goes my review.

Story (8/10): What I like about the manga is the plot. It is about a guy who underwent a brain transplant that changed his life. The way it was written was good. Although in real life, the possibility of a successful brain transplant is very low to impossible because of incompatibility and rejection. But here, putting reality aside, a story was made out of it that turned into something interesting. It is also showed the effects and consequences of fusing one brain from another for was they say, each brain is unique. However, what I disliked about it is the pace of the story and it was a bit anti-climatic. It was a bit predictable so the hype of any plot twists was borderline low. Also in the summary, it was stated that the effects felt and experienced by the main character was either due to the transplant or medication. But, the emphasis was more on the former and there was no focus on the latter or explanation. Nonetheless, I still enjoyed it.

Art (8/10): The art is great. It was well-drawn -- shadows, lines as well as the emphasis of the characters' facial reactions.

Character (8/10): I particularly liked the main character.

Overall (8/10): It's good for a thriller and psychological series. I would definitely recommend this to anyone.

My apologies for I am still new at writing reviews about manga/anime.
