Issei's death and rebirth in Vol. 11 & 12 are kinda similar to the comic miniseries Spider-Man: The Other - Evolve or Die.

In it, Spider-Man kills the main enemy (like how Issei killed Shalba).

Both main characters die shortly afterwards.

Spider-Man comes back to life after gaining a new body and abilities granted to him by a spider deity (in Issei's case by Great Red and Ophis who is a Dragon deity).
