The manga should've stopped after Chapter 116.

Everything that happens after Chapter 116 should've been a spin-off.

I would given the manga a solid 9, if it wasn't for the post-116 chapters.
Chapter 116 was a great ending and should've stayed that way.

Now for everything before chapter 117...
[SPOILERS]

Story:8
Very unique premise.
The main character starts of as a semi-conscious rock made by a higher being.
Ends up turning himself into a wolf after it dies.(we later find out he can turn himself into anything he feels a strong emotional connection towards, he learns to control this ability and also learns to [create] stuff)
Overall very gripping and emotionally driven. Shounen with some psychological elements mixed in.

Art:9
The art is like what you would expect of the author of Koe No Katachi

Characters:9
The most interesting part of the manga imo.
The characters feel very similar to Fire Punch by Tatsuki Fujimoto.
They are weird in a mostly non-cliche way.

Enjoyment: 4
This would've been a 9 if it wasn't for the post-116 chapters which I feel are like one big filler.

The manga can be quite "weird" at times, but overall I'd say it's a worthwhile read. (pre-117 at least)
