Wikipedia summary: <spoiler /><spoiler>
On noticing that Maria eat nothing but chips, Kodaka decides to start making healthy lunches for her. Kobato feel jealous because it appears that Kodaka is prioritizing Maria over her. As Kodaka gives Maria lunch, he learns that Yozora awards Maria with chips whenever she does something for her. Maria, satisfied after eating Kodaka's lunch, starts calling Kodaka her "big brother". Later, Sena completes another dating sim and wishes that she could be inside a game. Rika brings out a virtual reality game console and has everyone try out a beta release of a role-playing game. As they pick their character class, they have mixed feelings about their assigned costumes and abilities. Everything goes well in the beginning as they gain abilities and level up. However, the boss stage does not go well, because Maria falls asleep and goes offline. Yozora tricks Sena so that she is defeated, while Sena tickles Yozora in revenge. After the game ends in defeat, Kodaka is surprised to find that Kobato was playing Maria's character. She had come to the clubroom to see him because she was feeling too detached from her brother. She immediately clashes with Maria, and Yozora decides to accept Kobato as a member. Later that night, Kobato sneaks into Kodaka's bed, stating that she is Kodaka's only sister. </spoiler>
My comments:<spoiler /><spoiler>
Kotaka starts cooking lunch for Maria because she's only been eating junk food... Kobato is jealous that she's not the only loli character anymore. Also we find out she has dual personalities. Whenever she isn't wearing the colored contact lens she returns to being the more normal Kobato.
lol I'm liking this Kobato/Maria rivalry a lot more than the Yozora/Sena rivalry.
