Chapter 7/8[1][2]

Iori greatly dislikes Shokuhou Misaki, resenting her growth in body and clique.[1][2] She is prone to impatience and somewhat belligerent, being in favour of a prompt, violent approach at the candidate meeting.[1][2] Like most of the other election candidates, Iori was not willing to give up on her bid for student council presidency and support another's bid for the sake of stopping another one of her rivals.[1]

Iori's background is mostly unknown, but she was established as a clique leader by the time of the student council presidential election.[3][1] Her comments indicate that she was in that position when Shokuhou was still small and had just started her clique, and gained enmity for her as both she and her clique grew large.[1]

Iori attended the meeting Kamino held with the other election candidates (with the exception of Inubushi, who ignored Kamino's invitation) about potential cooperation and courses of actions in response to their two main rivals in the competition joining forces,[1] as Shokuhou Misaki and Gaouin Tsukasa were working together to find evidence that would exonerate Hokaze Junko.[6]

She participated in the joint attack the candidates launched against Shokuhou and Gaouin, first launching remote attacks on the pair after Kamino had sealed off space and trapped them. Missing with her attacks, she became impatient and passed the baton to Tatsuki Mirei. Shortly afterwards, she observed a break in camera footage and considered the possibility of a third party acting.[2]


The exact nature of Iori's ability is currently unknown, but as a student of Tokiwadai Middle School, it can be presumed to be at Level 3 or 4.
