7

Shoko starts visiting Sakuta’s home to care for a stray kitten she discovered. At the library, Sakuta observes Rio with her hair up and without glasses, prompting a discussion about her. Later, he and Mai see Rio enter an Internet café. When Sakuta attempts to call her, he encounters a second Rio inside the same building. This duplicate accompanies him home, proposing that their existence stems from two personalities moving through quantum teleportation. The other Rio agrees with this theory but claims to understand the cause. Meanwhile, Sakuta learns from Saki that Rio has been sharing revealing photos of herself on social media.
