Ep. 11: Akira trains Aika for her exam while Alice feels lonely before a surprise visit.

Two weeks after Alice's promotion to Prima, Akira hears Himeya Singles gossip regarding Aika, the company heir, losing to a competitor. Worried about Aika's well-being, Akira struggles to discuss the matter until Aika reveals her presence at Alice's promotion. Aika states that the competition motivates her and requests rigorous training. Akira schedules Aika's Prima exam for one month later, warning that she will not forgive failure given Aika's status as the future queen. Meanwhile, Alice adjusts to her life as an undine but lacks free time. She realizes it has been several days since she last saw Akari and Aika during their moon-gazing session. Although she misses her friends and feels lonely, she cannot find an excuse to contact them. The situation resolves when Akari and Aika arrive unexpectedly with a pizza, and Akari explains that friendship alone is sufficient reason to visit.
