Staying over at SÅta's house, Aoi explains her backstory about being constantly forced to study by her mother, inevitably pointing out the reason she ran away was because Kirio ate her natto. As the other staff members try to convince Aoi to return home over the next few days, Popura asks Kirio to bring over his mother, Kikuno, who is revealed to have trouble talking with others clearly to the point that her children need a manual to understand her. Conflicted over having never read the manual herself, Aoi runs off and comes across Haruna, who encourages her to get along with her mother. Aoi quickly rekindles with her mother, returning Haruna back to Otoo in the process, and decides to go back home.
