I lost any hope for this series to have any semblance of identity.
It's just CSM/Tokyo Ghoul knockoff, without adding anything new/non-mainstream (or making same things but with better quality).
I can't see it as anything else than combining two most popular seinen titles for easy buck.
Chainsaw Man:
MC merging with his dying friend/friends to gain superpowers
MC losing control and becomes the strongest Monster in the franchise
MC wants an average life (eating burgers etc.)
Change MC's hair color and I'd be fooled it's Denji (blander version tho)
A lot of characters wearing suits (in both cases allied "demon" hunters)
A lot of strong female characters (rarity to have so many introduced so fast)
Makima
Tokyo Ghoul:
MC is half monster, half human
Demon Hunters use similar weapons to those in "Tokyo Ghoul"
Known by demon hunters "succubus" are named in similar manner to "ghouls" from Tokyo Ghoul
Artstyle was definitely mostly inspired by Tokyo Ghoul
I have to say, the characters are rather dumb as fuck in this series. "Oh, we got a rather peaceful potential fighter, lets just off him." Like, that is not even a good way to use a disposable pawn.
