After Haruhi has Kyon add a logo of her design to the SOS Brigade website, a girl named Emiri Kimidori asks the SOS Bridgade to find her boyfriend, the Computer Research Society president, who has gone missing. After Haruhi gets bored and leaves after finding seemingly nothing in the president's apartment, the others discover that he is actually trapped inside a data entity in a sealed reality. After Yuki and Itsuki defeat the data entity and rescue the president, they realise that the logo Haruhi designed was the catylist for the entity. Afterwards, the president states that he has no girlfriend, leading Kyon to suspect Yuki engineered the case to stave off Haruhi's boredom.
