Izuku's Twin Sister?! - Mha

Izuku had a twin sister, Y/n. Many people thought they were the same person,

the same messy green hair,
the same goal to become quirkless heroes,
the same All Might obsession,
matching hero costumes.

But one day, Y/n finds out that Izuku got a quirk. Betrayed, she left behind her life to become a villain, being taken in by All for One.
