'New' character 2

Sureibu Aishi is the husband of Dozuki Aishi and the father of Ryoba Aishi.

Once a cheerful and energetic young man, he was kidnapped by Kataba Aishi and psychologically tortured by Dozuki Aishi until his psyche was completely shattered. This process turned him into an empty shell of a human being; he no longer exhibits a personality or shows any signs of independent thought.

He exists as "living medication" whose purpose is to alleviate the symptoms of Dozuki's Aishi Condition. Closer to a statue than a living being, he generally does not perform any type of action unless instructed to do so, including eating and sleeping.

To explain his state of being, Dozuki told his parents and acquaintances that he had sustained a brain injury that had left him in a nearly vegetative state shortly after their wedding. She claims to be his "caretaker," but, in reality, she only does the bare minimum to sustain his existence, thinking of him more like a pet than a human being.

He has never held a job, as his wealthy mother-in-law provides for him and his wife. When his mother-in-law eventually es away, he will become her replacement, and will care for his wife in the same way that his mother-in-law has been doing.

His daughter, Ryoba, feels immense pity for him. Because she would never wish to be married to someone who exists in such a tragic state, she swore from a young age that she would never mind-break her own Senpai, as her mother did.

Ryoba, like most women in the Aishi bloodline, inherited the hair color of her mother. However, Ryoba's sister inherited the hair color of her father.
