Honkai Mei Won't Dream of a Plankton

Am I Mei? Or Raiden Mei?

Do I know Kiana? Or do I know Kiana Kaslana?

Is this real? Or an illusion? Is this reality? Or have I transmigrated? Am I mentally ill? Or am I a transmigrator?

This is the story of Mei, who transmigrates into a world ravaged by the Honkai and searches for redemption. It's a story full of sunshine, a beautiful life, love, and hope.
