(The Ghoul arc is complete. The story is currently in the Seraph of the End arc.)
(Later corruption arc + decisive and merciless protagonist + the plot won't differ much from the original early on, but gets fun later.)
(Not a comedy! Not a comedy! If that bothers you, read no further!)
Ghoul World: Touka clutches Gu Chuan's hand and begs him not to go. Gu Chuan shakes her off, secretly delighted: "Sorry, Touka. I'm not going back to Anteiku."
Jujutsu World: Seeing his friend Suguru Geto about to split from him over their completely different beliefs, Gu Chuan chuckles. "I'm done being human, too!"
Demon Slayer World: Everyone is searching for the Sound Hashira, who has been missing for an entire week.
Gu Chuan: Huff, huff (working at the cram school...)
Across countless worlds, Gu Chuan plays all kinds of white-haired characters and makes a name for himself. You'll often see crowds chasing after him, shouting, "Kill that white-haired guy!"
Gu Chuan just gives them a wicked smile. "Only working at the cram school can make me stop killing, if only for a while!"
