Alice tells Akari and Aika she won't be at practice tomorrow because she invited Athena on a picnic. That night Alice makes elaborate preparations, but in the morning Athena leaves for work at dawn without speaking with her. When Athena finally returns, in her disappointment Alice snaps at her then accidentally rips the invitation, and in the ensuing fuss Athena slips and falls. Alice calls Akari and Alicia for help in a panic, and when they arrive, they learn that Athena has amnesia from hitting her head and cannot remember anyone around her. As they talk, her memories slowly come back, starting with President Aria and Alicia. To further jog her memories, they take her to familiar places, and by the end of the day she remembers everyone but Alice. When Athena asks what she was to Alice, the latter breaks down in tears, and Alicia makes Athena reveal she'd been faking amnesia to find out how Alice feels about her.
