Kazuhito is told by Kirihime to help look for her lost bra. After Kirihime punishes Kazuhito for trying to get her scent, Suzuna joins the search as Kazuhito ditches to read more books. When he was found out by Kirihime, the two argue and Kazuhito accidentally discovers Kirihime's kit of breast accession, leading him to get punished by Kirihime. As Kirihime and Suzuna continue their search, Kazuhito finds Kirihime's bra under his blanket. Fearing that Kirihime may torture him, Kazuhito plans to dispose Kirihime's bra. Meanwhile Kirihime searches for Kazuhito as she senses someone stalking her. Later on Kazuhito founds a maid performing solely while he was trying to bury Kirihime's bra. Eventually the maid discovers Kazuhito and attempts to kill him. By passing into a busy street, Kazuhito is nearly hit by a truck until Kirihime saves him in the nick of time. As Kirihime and the maid draw out their blades, their fight is postponed after the maid hears someone selling roasted potatoes. Afterwards Kirihime founds her lost bra on Kazuhito. Seeing a miniature dog design on her bra, Kazuhito deduces that Kirihime love dogs. Trying to act dog-like, Kazuhito instead got chased by Kirihime as someone continues to stalk the latter.
