Iroha Tamaki was in her bedroom in the Magius headquarters after getting found by Nemu Hiiragi an 11 year old magical girl who is a leader of Magius alongside Touka Satomi who was the same age as Nemu and they were friends with Iroha’s younger sister Ui.

“Big sis your awake..”

Nemu says as she closes the door and adjusts her glasses and puts some books on a nearby shelf.

“You’ll be staying here now instead of staying at the Mikazuki Villa with your friends..”

Nemu then gives Iroha a white Magius cloak and it has the Magius pin on it.

“Please put it on big sis after all you belong with Magius now..”

Nemu was stern and strict.
