Full Summary
Ainz Ooal Gown working in his study back in the Great Tomb of Nazarick is informed by Albedo that Narberal Gamma wishes to see him. Narberal asks if Hamsuke had came to Ainz, but unfortunately, Ainz reports that he had not seen the hamster not since Narberal took her to the surface for some fresh air.

Hamsuke wishing to help in her duties to Nazarick volunteered to deliver some research materials on the sixth floor. However, the monsters there have yet to report her arrival, which Ainz deduces that the hamster got lost. Albedo recommends a search be conducted to find Hamsuke, which Ainz agrees.

Elsewhere on the first floor, Hamsuke is trying to find her way back to the sixth floor. When several of undead tried to approach her, the hamster panicked running deeper into the tomb. From her undead underlings, Shalltear reported back to Ainz of what her underlings saw. When the female Guardians began to bicker, Ainz decided to have Shalltear and Albedo work together to improve their relationship. Narberal and Ainz then journeyed to the sixth floor to recruit Mare and Aura in their search.

Mare and Aura eventually tracked Hamsuke to the second floor and found Albedo and Shalltear there as well. Hamsuke who had encountered, Kyouhukou was given a cockroach guide to help her get to the sixth floor. The Floor Guardians, though excited at discovering Hamsuke, were shocked to see the insect on the hamster's head, and would not approach the beast. Aura attempted to force Mare to smash the bug, but the dark elf was unsure how to proceed. Hamsuke unaware of the discomfort she was creating attempted to approach the Guardians, but when she was threatened, ran deeper into the tomb.

Hamsuke's flight went short once she ran into Ainz and Narberal. Ainz had Narberal feed Kyouhukou's servant before sending him back to his master. To the Overlord, he thought this was a good relationship exercise as Kyouhukou aided the newly inducted Hamsuke. Back to the female Floor Guardians, they have retired to Spa Resort Nazarick to relax. All seems well until a brief conversation between Shalltear and Albedo concerning their chest sizes, causes another conflict.
