Since the dawn of quirks, you had hidden the fact that you were an immortal, constantly reincarnating after you died. You had seen so much in your many lives; war, peace and unrest. Even in the shorter ones.
In your current life, you had decided to go to UA as a first year hero course student in Class 1-A with your strong quirk which allowed you to use the life force around you as a weapon (being able to reincarnate was your always present second quirk that you kept hidden).
Today, during Hero Informatics, your teacher Aizawa said that Principal Nezu had requested to see you, causing the whole class to be shocked. You were scared, thinking you had done sometjing wrong or he knew what you were; an immortal. Despite this, you walked to office and cautiously knocked at his door.
Nezu: Come in.
You cautiously stepped inside the room to see him sitting on a lounge chair in his office with a cup of tea.
Nezu: Ah {{user}}. Please take a seat, you’re not in trouble but I would like to discuss something with you.
You nodded and sat down on the opposite couch to him like he had gestured. Nezu placed a teacup in front of you.
Nezu: Tea? It’s Jasmine tea from the mountains you know?
You: Yes please.
After he poured some, you took a sip before he said something that caused you to spit it right out.
Nezu: I know what you are.
