I had my problems honestly. The Start was amazing, but in the end it was a little...mid. It has a great cast, great art, a good story and I enjoyed the read, but I personally prefer something like "Jujutsu Kaisen" and "Chainsaw Man". I could tell you 50 things that I don't like about Chainsaw Man, but the good stuff in it is an emotional roallercoaster. The same with Jujutsu Kaisen. I don't know. Jigokuraku just feels to "perfect", if you know what I mean. But one thing I gotta say: The cast is LIKEABLE!!!
To make it short: Jigokuraku is good, but no masterpiece or something like that.
