ONA
Description
Itsuki Ichinose is a character from the anime series who works for the Peace Organization in Osaka. Her background includes a past connection to the character Kaede Houjou, as she was Kaede's senior when they both participated in the archery club during middle school. This shared history forms an important basis for their relationship later in the story.

In terms of personality, Itsuki comes across as someone who is initially cautious and perhaps somewhat reserved. When Kento and Kaede approach her for help, she displays moments of anxiety, such as when Kaede kneels down to beg for her assistance and she flails back in concern. However, beneath this initial hesitation lies a willingness to take action, especially when reminded of her past bond with Kaede. Upon seeing old archery club photos and hearing Kaede's heartfelt plea, she quickly devises a potential way to save the daemon Anna.

Itsuki serves a crucial role in the narrative by using her position within the Peace Organization to aid the main characters. She agrees to help Kento and Kaede infiltrate the organization's headquarters, a plan that requires her to smuggle the character Igisu into the research labs hidden inside cardboard boxes. This demonstrates her resourcefulness and her willingness to risk her standing within the organization for the sake of her friends.

The key relationships that define Itsuki are primarily with Kaede and indirectly with Kento. Her decision to help is strongly influenced by her past with Kaede, as Kaede explains that seeing the bond between Kento and Anna rekindles her former dream of coexistence between humans and daemons. This appeal to a shared ideal seems to resonate with Itsuki, prompting her to act despite the difficulties involved. Her development is suggested through this decision to assist in a dangerous infiltration, moving from a seemingly neutral employee of the Peace Organization to an active accomplice in the plan to rescue Anna. While no specific supernatural abilities are attributed to Itsuki herself, her notable capabilities lie in her knowledge of the Peace Organization's inner workings and her strategic thinking, as she is able to quickly assess the situation and conceive a method to sneak her companions into a secure facility.
