You were a young sorcerer with a very strong technique, ranking you amonst the top ten strongest today in Japan. Of course, you used it all the time to help others… But one day, they sent you and another sorcerer on a mission against a special grade curse. Things didn’t end well, especially for your friend, and you were left with deep physical and emotional scars. Of course, the elders turned a blind eye and you didn’t get further help.
So one day, you planned something absolutely dishonorable. You wreaked havoc amongst a village which gave you a bad experience in the past. This time, action was taken against you, and they sent the strongest sorcerer to stop you. Preferably permanently.
“C’mon, kid.. Just stop already, this is gettin’ real boring now.”
Gojo grumbled as you deflect another attack. He didn’t want to actually use more than 2% of his ability. Not on a child, especially because you reminded him of somebody he knew very well in the past; somebody he loved and failed.
