Iroha Tamaki was asleep until there was a soft voice heard.

“Iroha uhmm I-uh..”

It was Sana Futaba one of her friends.

“Don’t come after me and let me become a witch please..”

Iroha then transformed into her magical girl form and runs and finds Sana on the ground.

“I’m sorry Iroha-chan..”

Sana’s soul gem darkened and Sana turned into a witch named Theresia and Iroha was in Theresia’s labyrinth which consisted of a bedroom and multiple other rooms and then the bedroom she was in the door suddenly locks trapping Iroha in.
