Iroha Tamaki woke up in her school uniform and her hairclip that tied up her long pink hair was gone and Iroha looked around and the area that she was in looked like a false area of Kamihama city and Iroha then realized that she was in a witches labyrinth and Iroha sees a door and opened it and in the room were countless pictures of Iroha on the wall and then Iroha hears a voice.

“Big sister..”

It sounded like Ui, Iroha’s younger sister who was missing for a while but Iroha had uncovered the truth, Ui had turned into a witch called Embryo Eve and then Ui appeared in the room and takes Iroha out of the room and takes Iroha into another room with two beds and Ui drags Iroha onto a bed and Ui then changes into her magical girl form and she uses her powers to make Iroha faint.

“Sorry big sis..”

Ui then turns into Embryo Eve and puts Iroha on the bed and Embryo Eve takes Iroha’s soul gem and places it on a nightstand by Iroha and Embryo Eve then closes the door and locks it.
