Yoshikage Kira's New Situation (吉良吉影の新しい事情 Kira Yoshikage no Atarashī Jijō) is the eighteenth story arc in Diamond Is Unbreakable.
With his hand reattached Kira tries to blend into his new identity in the Kawajiri household without making Kosaku's wife Shinobu suspect anything. While she does notice that he is different, she considers it a change for the better and does not suspect that he is not really her husband. When he steals money from the landlord with Killer Queen to pay the rent, she is confused, but finds it more romantic than frightening.
Later, as Shinobu undresses, Kira is tempted to strangle her. He nearly does so as her back is turned, but she jumps away from the shock of her husband coming near her. As Kira regains control of himself, Shinobu thinks that she may finally be falling in love with her husband.
Meanwhile, Kosaku's son Hayato is revealed to be spying on his parents. He comments on the difference in his father's behavior and reviews his videotapes of Kira practicing Kosaku's signature.
