Ep. 4: Ruri seeks connection with Nagi through gaming recommendations in Akihabara, leading to a dōjinshi discovery.

Ruri attempts to bond with Nagi by acquiring games, but Hayate warns that Nagi dislikes social interaction. Chiharu and Kayura suggest purchasing titles, only to discover Nagi has already played them. The group then travels to the Akihabara district, where a heated debate ensues regarding preferences for manga, anime, and games. Ruri requests recommendations from the pair, and they proceed to Wataru Tachibana's shop. While the trio argues over which manga Ruri should read first, she accidentally wanders into the R-18 section and flees in horror. Ultimately, she purchases a dōjinshi titled "30 Days of Soul Burning" from an unknown author. Hayate subsequently identifies this work as one of Nagi's original creations, revealing a hidden connection to her reclusive friend.
