Aiho first contacs Sumomo, along with Hakutou and Kurumi, 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. Sumomo answers Aiho plainly, confirming to her that she has indeed become suspicious of the information blackout regarding Fräulein Kreutune.

Here, it is shown that Sumomo as well as Hakutou were tasked to search information regarding their prey, but is being interfered by someone. 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. Sumomo warns though, that whoever is blocking information is most likely a step ahead of them.

It is assumed that she acquiesces to Aiho's order and rendezvoused with Hakutou.
