Sana shares beach vacation photos with Junna and Senna, prompting Senna to suggest creating new albums. Junna believes reviewing old albums might help him regain his lost memories, but Senna admits she accidentally discarded them. The group decides to purchase a new album instead. At a bookstore, Junna spots Tomo but she disappears before he can approach her. Later, they meet Koutarou Ryuuoku, a researcher who worked with the twins' father. He discusses a dial found at an excavation site and asks the twins if they recall anything about it. Junna struggles to remember, while Senna tearfully claims ignorance and retreats to her room.
