Jujutsu Kaisen: I Speedrun the Culling Game with My White Moonlight

[Jujutsu Kaisen Fanfic] [Dual Transmigration] [Gender Swap] [Bringing My Girl Along] The protagonist left a comment under a Jujutsu Kaisen short video saying, “I want both of them.” As a result, he transmigrated into the Jujutsu Kaisen world with his beloved, and they both changed sex. I became Maki Zenin, while she became my younger sister, Mai Zenin. The System said our twin-bond restriction had been lifted, and I was now a Heavenly Restriction tyrant beyond the original. Then let's cut the chatter. Sis, hand me the Split Soul Katana. Watch me speedrun the Culling Game as a fully equipped tyrant, then take down Sukuna!
