Of the three that Aiho contacts in the public bandwith of Anti-Skill, Kurumi's style of speech shows that anxiety and worry, insisting on using a private channel to communicate with her colleagues.

Aiho first contacts Kurumi, along with Hakutou and Sumomo, after becoming suspicious of the strange information blackout regarding the attack on the Windowless Building, as well as the movements of the not-too-subtle Fräulein Kreutune. Kurumi answers directly, but pretty much confirms that she is aware of it too, as she asks all of them to speak in a private bandwith. For most of the conversation Kurumi insists on changing the bandwith.

Aiho later plans on taking Kurumi, and tells both Sumomo and Hakutou to go back to the station to secure paper reports if possible, if not, then retrieve the temporary cache from the copier. It is assumed that she acquiesces to Aiho's order and rendezvoused with her later.
