One of my best friends asked me to read this manga for him:
And i really enjoyed it!!
At first the manga felt like a drag because i had so many other mangas to read, but when i actually got down to reading it, it was very easy to consume. Jigokuraku has a great story, a power system that isn't too difficult to understand (but the names of the "tensen" are hard to remember) and great characters - I would argue that the characters are the best part of the show.
Every character has a backstory and motives to complete, like Gabimaru - his goal is to return to his wife and live a regular life with her. They are all likable my favourite ones are Yuzuriha and Gabimaru, Sagiri and Shugen are cool too -- With so many likable characters what is there not to like about the manga!
I should've completed the manga earlier and i can see why it gets all the hype. Please read it or watch the anime as well (i haven't watched it yet and I hope they did it justice).
