Moon Cancer-class Swimsuit version of [[Sessyoin Kiara]] introduced in [[Fate/Grand Order]]'s event [i]Servant Summer Camp[/i]. Her outfit changes depending on her Ascension level. [spoiler]Struck by an instant death attack, Kiara respawned in place of her formerly defeated self in [i]SE.RA.PH[/i], mortally wounded at the bottom of the sea. There, she found and consumed the "clam-monster Shen":[https://en.wikipedia.org/wiki/Shen_(clam-monster)] and mermaids, becoming a Moon Cancer-class Servant. She then formulated a plan to try to redo her childhood and affect the antagonist's plans by returning as a young girl.[/spoiler]

An [[aged down]] [[sessyoin kiara (lily)|version]] is also seen in the story and as the event shopkeeper. She's treated as a separate character from this one.
