- Tamaki Iroha
- Togame Momoko
- Akino Kaede
- Minami Rena
Dreaming of seeing her sister in hospital, Iroha calls to Kyubey to cure her illness. She remembers that this was her wish after forgetting it.
With Ui's disappearance, Iroha investigates in Kamihama City. After the bus ride, she finds another Witch's labyrinth encountering magical girls, Togame Momoko, Akino Kaede and Minami Rena. The group agree to help Iroha search for her sister.
The Satomi Medical Center's wing cannot be accessed, yet rather than Rena using her transformation magic to sneak in, she ends up fighting with Kaede.
Although Kaede attempts to reconcile with Rena, the Chain Witch ambushes them. They are targeted since they are trying to make up after having written their names on the Friendship Ending Staircase.
