Ikaruga finds special information and tips the 35th Platoon information. They found out about the magical artefact trade would be done on that day and decided to have a undercover operation and catch the criminal in hopes to get points. However, Ikaruga says that the undercover mission is not suitable for Ouka and tells her to consider dropping out. Ouka, who says she has been insulted and have done undercover operations numerous times, insists on going on the mission. However, she realised she was baited by Ikaruga, and wanted the mission to end quickly. Ouka was uncomfortable, but Takeru on the other hand, seemed to be comfortable since he was used to night jobs. Soon, they found their target and Ouka attacks their target when he accidentally touched her bottom and shot a bullet at the parcel which was suspected to be the magical item. When they named themselves as the Inquisition, they realised that the item in the parcel was not the magical item, and that their target was the wrong person. However, they managed to catch the real person and get the item, which they found out later was a F-rank item that was a ring. Later, Ikaruga tries to test the ring, and due to some reasons, Takeru ends up with the ring and see a bright pink light that makes the platoon members except Takeru who's wearing the ring to become drunk. Usagi tells Takeru he smells nice and licks him, while Mari tries to show her flat chest and cry, and Ouka hyper, and Ikaruga who vomits. Even Lapis is drunk and hiccups.
