In one of Kitsune’s dialogues, after she proposes marriage to the hero, she mentions “Is’s.” What could this be referring to? Could “Is” be the name of a character or something related to Kitsune’s story, or is “Is’s” simply a typo?
(Well, 'by Is's grace, only parting in death', after all. Humans are tragically short-lived, after all. No offense.)
