Episode Title:
The Memory of a Summer.
Episode Description:
Ichika Orimura has a dream in which the warrior woman from before suddenly turns evil and strangles him to death. He is later awoken by Laura Bodewig, who is wearing a one-piece swimsuit. After she suggests for the two of them to go a newly reopened water park, she storms out in anger when he plans to invite the other girls. Laura decides to go shopping with Charlotte Dunois at a mall, where they end up becoming models in a clothing store and heroines in a hostage situation while working at the maid cafe. Charlotte and Laura enjoy eating crêpes afterwards. Meanwhile, a mysterious female code-named "M" infiltrates a heavily guarded facility in England to retrieve a confined IS using the Silent Zephyrus, an extremely powerful IS. Ichika and the girls have a fun time at the water park, despite him being blamed for presumably inviting each of them on a date. They go down on a couple's water slide and participate in the summer festival. They close by lighting sparklers, which marks the end of summer vacation. At the same time, Chifuyu Orimura and Maya Yamada check on an incident involving a new IS.
