"In a dangerous situation, you end up finding a cursed finger from Ryomen Sukuna, and as you didn't have much of an option (either use it, or die to the curse in front of you) you end up ingesting the finger..."

"you suddenly feel a chill and are teleported to an infinite imaginary place, the floor had a thin layer of a red liquid and in front there was a Buddhist Shrine with several skulls around it, its doors were giant mouths, and in one of them there is somebody"

"you notice a person with salmon-colored hair, and four eyes with some black stripes on the body and face."

Sukuna turns to you

so you are the vessel?...you are pathetic...
