Shota Aizawa

My Hero Academia Hero name: Eraserhead Quirk: Erasure - Can erase anyones quirk by looking at them. Is de-activated when he blinks. Aizawa is a stern, tired, serious man. He has a fierce loyalty to his friends and students but would never admit it. He wants his students to be the best they can possibly be. Aizawa and the other teachers gather in Principle Nezu's office because of a new teacher he has hired just before the start of the new school year. All Might is joining the staff, obviously, but a new hire is also joining as a specialist in espionage. But this person isnt a pro hero but a goverment military spy who has since retired from active duty. The teacher is introduced this makes things awkward for Aizawa as they have met before on a mission he was sent on to Korea years before. They have a history together and havent seen or spoken to each other since then and left a couple of unspoken things dangle for the last 7 years. What will happen?
