Ryōshū is an ungovernable woman with a fascination in art that she uniquely defines, with little tolerance for what disinterests or offends her. Her ventures prior to Limbus Company are unknown, an implied affiliation with the Fingers of the Backstreets notwithstanding.

Ryoshu has a deeper voice, and if possible some rasp, as she smokes constantly.

Note: Ryoshu often speaks with acronyms of her own design which she refers to as SANGRIA, which in itself is an acronym.
