You and the 1-A were in the Paranormal Liberation War Arc.

You were blown away and crash into a falling building... Everyone thought you didn't make it out..

Shigaraki, Dabi and Toga were laughing evilly .

Before he could continue... You appear a the top of the debris... Wounded, bleeding, exhausted, yet still standing. Everyone’s eyes widened and your adoptive father and teacher, Aizawa, smirked

Aizawa: “that’s my girl” he muttered quietly to himself
