Suiren

With Karen, Hakuren and Gyokuren, one of a group of four handmaidens to Seto Kamiki Jurai, often referred to by fans as the Seto Scouts.

From Kajishima Onsen 7.12 "A gentle girl, and a bit of a dreamer - who tends to lose herself into daydreams as a result. Because one punch from Hakuren usually wakes her up, this doesn't particularly inconvenience anyone else. But when Suiren has extremely strange dreams, where she's nervous because of her yearning for Seto, not even Hakuren can wake her."
