Rena's mother began her career as a designer at a small clothing manufacturer in Okinomiya, where she met Mr. Ryūgū. They married and lived in a small apartment in Okinomiya until Mrs. Ryūgū became pregnant; they then moved into Rena's paternal grandmother's house until Rena started elementary school. Around this time, the manufacturer Mr. and Mrs. Ryūgū worked for started experiencing financial difficulties, so she began to consider going independent with a few other designers. The situation became complicated, but she received an offer to work at a design office in Ibaraki and accepted it. The company promised Mrs. Ryūgū a significant project, as the firm had high expectations of her talent. When the family moved, Mr. Ryūgū had to give up his job and became a homemaker. Mr. Ryūgū struggled in his new role; initially, he took a clerical job at a small company but kept changing jobs. His inability to manage household tasks, especially cooking, led Rena to take up the chores for him. Rena's mother frequently sent a lawyer to their household in Ibaraki but refused to meet him in any form, including over the phone. Mr. Ryūgū became depressed, as did Rena. One day, Rena met her mother again but did not speak to her; Mr. Ryūgū had given her a letter to deliver to her mother, but her mother did not read it when Rena asked her to. That meeting was the last time Rena's mother saw Rena. In Tsumihoroboshi-hen, Mr. Ryūgū begins a relationship with Mamiya Rina. He met her at a gentleman's club in Okinomiya named Blue Mermaid, where Rina is the private manager. Unaware of her relationship with Hōjō Teppei, Mr. Ryūgū falls into their badger game trap. It is implied that the two had slept together, as Rina lies about being pregnant to lead him into the prospect of marriage. Before she can finalize the plan and have Teppei intrude while they are in bed together, Rena murders Rina. However, Teppei still attacks Mr. Ryūgū late at night and is subsequently murdered by Rena. In Minagoroshi-hen, a similar scenario was set to occur, but Rena talked to her father about the issue instead of taking matters into her own hands. Mr. Ryūgū also gets a new job in this arc.
