I Became a Devil in Chainsaw Man

It's pretty cool, but it feels a bit awkward to always call the protagonist "I" instead of his name, and the protagonist has no sense of existence. Also, since the protagonist is a steam demon, why can't he be immune to physical attacks? It's good that the protagonist has a much higher sense of presence, but as a demon, the protagonist can actually injure ordinary people, and he does so very slowly.

It looks good and has the feel of Chainsaw Man, but the protagonist doesn't feel very involved.
