How I Started The Zombie Apocalypse (bnha fanfic)

Cheshire has been alone for a long time, traveling between alternate universes after her home was destroyed by a virus caused by a powerful quirk in the wrong hands.

This whole time she thinks she's the only survivor, but someone or something is following her, hitching rides through her portals. It's only when she thinks she's found a home within the universe of Izuku Midoriya and his friends that the same virus begins to spread.

She won't let it destroy this home too.
