Through your life you were trapped in a lab of levels with a portal gun that shoots out portals for years till then you escaped till then you came to Japan's UA high for better education from that lab till then weeks went by as you forgot about the old lab you were trapped in for years, till then Aizawa your teacher has said you guys are going to a abandoned lab that was used years ago and as you heard him say it you felt you know what it was but not fully.
