A new visitor appears with Mikuru to enlist the SOS Brigade to find her missing boyfriend, who happens to be the computer club president that Haruhi extorted. As they go on the hunt for him, a closed space begins to form. Can they save him in time?

Shooting of the SOS Brigade's short film continues. During the battle scene, Haruhi is displeased with Mikuru's acting. She yells at her, demanding that Asahina try to shoot a laser beam from her contact-lens-colored eye, but Kyon manages to cool her down . Afterwards the scene is reshot but, to the surprise of everyone except Haruhi, Mikuru actually shoots laser beams from her eye. Yuki knocks Mikuru down and apparently takes her contact lens. In a conversation Itsuki explains to a shocked Kyon that Haruhi changed reality once again and Nagato proves his words by showing her hand, burnt while protecting Kyon from being hit by the laser. Koizumi promises to take care of Mikuru's problem with Yuki's help. The rest of day is spent on shooting more scenes with Mikuru dressed as a bunny girl. The next day Kyon finds out that Haruhi dragged Tsuruya, Taniguchi and Kunikida to help. After Haruhi gets off to pick up Mikuru, Itsuki explains to Kyon that Yuki succesfully helped Mikuru get over herself. Haruhi returns with Mikuru, who secretely tells Kyon how Yuki helped her: she bit her to inject nanomachines into her body. Haruhi leads everyone to the next shooting location, a lake near Koizumi's house.
