Bell Cranel Jujutsu Sorcesser

The Little Rookie Bell Cranel had an old box giving by his grandfather when he was younger. He promised to keep safe because inside was one of the fingers of the infamous sorcerer Sukuna, a man so powerful that gives God chills on their spines. While saving his friends he swallows one of the fingers and gets posses. Now it's up to him to become a Jujutsu sorcesser.
