Iroha Tamaki was trapped in some sort of world that looks like it was made for her and she was on a bed and she gets off the bed and steps on a staircase that led up somewhere and she continues to walk up the stairs until she reached a room but she tried to leave but she accidentally fell over.

Touka: “What was that..”

Nemu: “I don’t know..”

Touka and Nemu who were both leaders of the Magius and were friends with Iroha’s younger sister Ui and they were 11 years old making them younger than Iroha and then they opened the door.

Touka: “Big sis..?”

Nemu and Touka then help Iroha up.

Nemu: “We made this place for you big sis..”

Touka: “Don’t you like it big sis.!”

Touka and Nemu then lead Iroha back to her room and they sit down at a kiddie table.
