Natsuki is a core member of NORA, operating directly under the group's leader, Haruka Inaba. She functions as one of Haruka's primary subordinates, sharing a "Co-Dragon" role alongside Yataro within the organization. Natsuki shows unwavering loyalty to Haruka and actively participates in NORA's operations.

She suffers repeated unwanted attention from Soumei, specifically when Soumei takes control of Yataro's body. During these possessions, Soumei subjects Natsuki to inappropriate physical advances, including groping. This behavior causes Natsuki significant distress and leads to strong disapproval from both Natsuki and Haruka regarding Soumei's use of Yataro's body.
