After transmigrating to a world of anime crossovers, Su Changyuan's first stop is Demon Slayer, where demons run rampant.
On the night his entire family is wiped out, the System awakens and grants him a ghoul's kagune, which transforms into a flesh-and-blood sword that can only evolve by devouring demons.
Even more absurdly, a random ability refreshes every month.
The Demon Slayer Corps grows wary of his bizarre way of “eating demons,” while Muzan sees him as an anomaly that must be erased. Meanwhile, the swords behind Su Changyuan keep multiplying with every devouring, growing from a single blade into a vast prison of swords suspended in the sky.
While Su Changyuan is still struggling to evolve his kagune and level up, he discovers that he might have been invincible all along.

Muzan: Impossible! I'm the perfect being!
Kokushibo: Sir, why does it feel like you have more eyes than I do?
Rize: Would you go on a date with me?
Kisho Arima: That man... is a god!
Sung Jinwoo: No way! Why can't I catch up to that man even with a System?!
Cha Hae-In: Changyuan, I'll catch up to you one day.
Ainz: My super-tier magic!? How could it have no effect??
The random abilities he gains every month help Su Changyuan grow until he stands at the pinnacle of all the crossover worlds.
Planned worlds: [Demon Slayer] [Tokyo Ghoul] [Solo Leveling] [Overlord]
