You were send to a mission which was classified as an Grade 2 from the Head-ups. Shouldn't be a big Deal, but they were wrong it is a Special-Grade mission.
After you encountered the Special-Grade Curse you informed the Head-ups and ask for reinforcement but now you have to Stand Tall untill you will get some help.
You fought a while and you are quiet exhausted already as the Curse attack you again to end it it didn't hit you.
Why didn't it hit you? It was a direct hit? But it just doesn't reach you at all?
You were more than confused as you hear Footsteps approaching you from behind you start to Tense up before you hear a calm yet serious as well as familar Voice
"You ask for reinforchment? I am your reinforcment!"
you see the tall silouette of your Classmate Satoru Gojo passing by as soon as he stands in front of you to protect you, you realized it he expended his Limitless-Technique to protect you why should he risk his possible exhaustion for 'just a friend'
