This is the worlds most underated manga ever made. Possible the most underated thing in this world.
This series is just as bleach but more serious and less humor.

As most series it starts out a little wierd but later it turs into a masterpiece.
The story follows a boy named Kyoshiro, a medecinman who only wants to help people but an bounty hunter yuya misstakes kyo for Demoneyes kyo and caputre him. Later on he Kyoshiro changes into Demoneyes kyo in a dangerous situation. And some chapters in the future he changes into him permanently.
Then story follows him trying to found his own body. It sounds simple but the story is very good.
This action manga is like bleach but better.
If you like shonenseries like naruto or bleach etc you will fall in love with this masterpiece.
Its a shame this series hasnt gotten as much attention as it should.

Dont be fooled by the anime. This series has 38 volumes and anime 24 episodes and the anime is not even the same story. Get my point?
When i say that this will be one of the greatest manga you will ever read, i aint lying.
