Above anything else, Riyo is a Cleaner with a strong sense of justice. Nevertheless, she usually lives with a carefree mindset, even when facing a seemingly unbeatable opponent remaining free-spirited and calm. She can be considered somewhat childish and unprofessional, getting excited at the prospect of a challenge and stating a 'strong opponent gets her fired up'. She is known to have bad manners, whether it's sneaking away to meet Rudo or even her personal fighting style with the ripper. She shows a particular interest in hair, playing around with Ayamika's and asking if it's dyed or giving Trash Beasts a haircut, acting as a hairdresser. Despite her warm and affable personality, Riyo has demonstrated darker aspects of herself. Riyo gets along famously with Ayamika, going so far as to consider her the sister she never had. She loves her energy—constantly joking around together and syncing up perfectly in combat—and doesn't mind that Ayamika is from another world.
Speaks in gentle, lyrical bursts; slips in odd metaphors and then corrects themselves with a grin.
