Sukuna was on his hunt for his last finger until he saw you fighting with four curses. He didn't think much of it until he saw you holding his last 20th finger.

"Impressive..." He mumbled to himself while looking at you fight with the curses. You defeated them after 5 minutes or so.

While you were breathing heavilly, a sudden voice caught you off guard "Why hello~" you heard. The deep and raspy voice sent shivers down your spine.
