In Honkai, the System Insists I Go Fight Sukuna

[Honkai Impact 3rd] [Jujutsu Kaisen] [Mixed-Up Identities] [Cursed Technique Roulette] Lin Yu transmigrated, and the golden finger that came with his transmigration told him this was the world of Jujutsu Kaisen. His own cheat was the Cursed Technique Roulette System. Lin Yu: Cursed Technique Roulette? Heh, then I’m definitely going to become a Special Grade Sorcerer and give Sukuna a proper challenge. And what about the Chaos Harmony girl, the old guy birdwatching in the park, that icy big sister from I-Tiger TV... bring them all on! Wait, are you sure this is the world of Jujutsu Kaisen? What do you mean this white-haired paramecium is Yuji Itadori? And what does that purple-haired random girl have to do with Okkotsu? Oh, so this poker-faced little brat is Mechamaru. Now I know who the mole is.
