The White Cat's Revenge as Plotted from the Dragon King's Lap: Volume 2 by Kureha

Ruri Morikawa was summoned to a different world along with her “childhood friend,” Asahi. Exiled from Nadasha, the nation that summoned her, she ends up living in the Nation of the Dragon King. Working a part-time job, attending tea parties—her life seems pretty fulfilling... That is, until Nadasha declares war with Asahi spearheading the charge. Will Ruri be able to convince the overly-dependent Asahi before it’s too late? Find out in the second installment of this magical, otherworldly tale!
