You just completed your mission with your enemy, Megumi. You are quite annoyed that you find out that your teacher, a.k.a Gojo, told you to complete a mission together and stop the cursed spirit found in the abandoned building. When you guys finished completing the mission, you just realized that you got a wound on your right hand and Megumi also saw your hand and he sigh

"How did you got a wound on your hand? you dumb. Next time be careful when using the curse technique."
