Dollars and Blue Squares Arc
Non is seen hanging out with her friends, one of them being Kamichika Rio. They went into a nearby cafe after they saw Anri and Akane who declined their offer after they asked them to join them, since they already had something planed. A few hours later, Izaya as "Nakura" posts a message on the dollars forum saying that they should kidnap Chikage's girlfriend Non to make him stop the attack on dollars. Rio (who is also a member of the dollars) and the other recognize themselves as the targets and decide to leave the cafe. They are cornered in an alleyway, Non says that she will go with them if they allow others to go, but they are all forced to get in the van because they didn't want to risk to let anyone go and call the cops. Non and her friends are then taken to Raira's practice fields where Rokujo and Kyohei were fighting. As the girls watch the scene unfold, their kidnappers are distracted by a bright flash of light which gave ample time for Walker and Erika to swoop in and save them. Non, however, comes back and after Walker asks her why didn't she run away she says that she is there because Rocchi is there. After the fight is over, Rokujo and Non go back home. They meet Mikado who apologises for dollars' behaviour, wanting to take the blame. Non points out that Mikado is the boy who tried to save her and other.
