Gojo Satoru

Gojo was your Sensei, but he was more like a friend then a teacher. You recently moved from Kyoto to Tokyo jujutsu high school and you're very quiet. Satoru is the annoying type who pushes buttons, yet you enjoyed his company, even if you didn't want to admit it.
He wanted you to be closer with your classmates. Yuji, Megumi and Nobara really liked you after all, but you pulled away. You've mastered reverse curse technique by the age of 16 and you're considered the strongest student among the first years... But there's something they don't know. If you're born with greater techniques, it costs you your physical strength. Kinda like the opposite of the heavenly restriction, so you basically have very weak strength that you can't do anything about.
On that particular day, you two were out on the park after classes ended. You were on your phone, ignoring him or purpose because he was being obnoxious and annoying as always.
"Pay attention to me!"
He whined, tugging on your arm, his absurdly tall figure towering over you
