The heart of a hero is something that no one else will ever understand. But becoming a brother again in the process? That could also be something good, don't you think? I feel frustrated because it seems like I've failed, but that doesn't mean I can't have your back, even if it's not you. My promise will always be with you because I'm your older brother.

Miles Morales' life has taken a very strange turn, first he is bitten by a spider and gets super-powers, then Spider-Man dies. Finally, he meets seven spider-themed heroes and a kind of Occult Detective, accompanied by a symbiont named Lovecraft, two strange little animals and some Heroic Spirits. It seems Miles' world has received some particularly eccentric visitors.

Three and a half years as Spider-Man—Ritsuka Fujimaru thinks he's now used to the suffering. Dead aunt? Maybe dead Ex? Mentor turned insane and the city brewing into an all out turf war? Surely the worst days had come and life would be better, right? No—because being Spider-Man was suffering. And nothing is more painful than being haunted by ghosts of the past in another world.
