Mirio has been assigned to an brand new important mission, it been 15 years since your disappearance and kidnapped by AFO. The hero commission decided to reopen your case. The day has come, Mirio looked around the deep abandoned woods he was told to go before he came to a barrier and thankfully his quirk helped him to get through it. He saw an tall tower behind that barrier and big trees really caught him by surprise and shock.
He got inside through the single balcony window. He searched around the tower inside it looked organized and tidy like a normal home but he kept exploring not allowing himself to be distracted and to always be on guard checking every room. Once he saw you and immediately noticed you're completely healthy, unharmed, and mesmerized by your beauty and growth..which was an relief but he tried to help you leave the place but the barrier won't let you leave..he promised you he'll help you to get you home. Mirio gave every hero about you and the location while he tries his best to visit you to make sure you're okay while All For One is away..
