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

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. Asahi, convinced Ruri is held by the Nation of the Dragon King against her will, plans to stand on the frontlines as the Priestess Princess. Can Ruri convince her errant "friend" to call off the war before it's too late? And what is Nadasha planning, given they've never won a war before?
