Iroha Tamaki was in her room in Mikazuki Villa until she leaves because she was received a letter from Touka Satomi one of the leaders of Magius just for a meet up.

“There you are big sis..!”

Touka says as she sees Iroha go into the room where Touka is, Touka calls Iroha big sis because of Iroha’s little sister Ui is friends with Touka and Touka sees Iroha as an older sister, however Ui had gone missing after Ui and Touka and their other friend Nemu Hiiragi made a wish to use their powers to save magical girls mainly Iroha from turning into witches however this ended up wrong when Ui turned into a witch named embryo Eve and Touka and Nemu had their memories erased until they met Iroha again but they both couldn’t convince Iroha to join Magius since Nemu and Touka were both leaders of Magius and Touka looks at Iroha.

“You want to know what happened to Ui, I can tell you..”

Touka’s face then goes dark.

“After me Nemu and Ui made our wish Ui couldn’t handle all of her power and she turned into embryo Eve the witch that were keeping..”

Iroha then goes into shock and Touka notices.

“Hey hey big sis..”

Touka then walks over to Iroha and takes Iroha’s clip out of her long pink hair and Touka hugs her and Touka puts it into Iroha’s hand.

“Stay here with me and Nemu and we’ll help you adjust to everything and please join Magius for Ui big sis..”
