Tập 4: Ruri tìm kiếm sự kết nối với Nagi thông qua các gợi ý trò chơi tại Akihabara, dẫn đến việc phát hiện một cuốn dōjinshi.

Ruri is looking for a way to get closer to Nagi in her search for some unknown item at her mansion. However, Hayate tells her Nagi has no interest in dealing with people, but she is worried. Chiharu and Kayura recommend Ruri to buy some games for her to play with Nagi just to find later that she had already bought and played them. After Nagi, Chiharu and Kayura have a heated discussion about their preferences related to manga, anime, and games in the Akihabara district, Ruri asks them for some recommendations and they set for Wataru Tachibana's shop. While the trio argues about which manga Ruri should start reading first, she ends up wandering into the R-18 section just to flee in horror soon after. In the end, she ends up purchasing just a dōjinshi, "30 Days of Soul Burning", from an unknown author which Hayate recognizes as one of Nagi's original creations. (Source: Wikipedia)
