Demon Warrior Who Lives a Low-Key Life in the Academy

I've traveled through time in the game. But I have a cheating ability, which is to have overwhelming combat power output against demons. But in my normal state, I am too weak. In order to avoid conflicts with students, I must keep a low profile. Lila Sophiaen "Oscar must have hidden the identity of the great magician for some unknown secret. I must help you and give you a monkey." Ava Novalis "Oscar, I don't know what a friend is. Can you teach me what a friend is? I hope we can become lifelong and only friends." Sophie Ravenclaw "Junior, your training is not enough. Let me help you." I feel very troubled. You college stars should stop pestering me. I just want to live.
