After the Game Shut Down, I Became a Female Teacher at the Academy

[Transmigrate + transformation + yuri + academy + prophetic protagonist]

The popular girls' mobile game shut down after seven years, its main story ending in a "corruption ending."

That night, a longtime player transmigrated into the game world as a silver-haired, red-eyed teacher, Nyx Cosmos.

No System, no cheats, just seven years of game experience.

The demon race invades, the academy falls, and the students meet tragic ends...

"Then let me, the person who knows this game best, teach them all over again."

This time, no one will die.
