Rinko has very long blue hair that goes to her ankles. She also has purple eyes and a giant bust. Her Taimanin suit is a purple bodysuit with gold accents on the clothes' edges, golden pasties on the tips of her breasts, an opening in the center of her bust, silver armored gauntlets and leggings.

Rinko follows a strict warrior code and values training, when forced to kill she's fast and merciful but also is competitive and gets sometimes lost in battle. She can suppress her emotions and put on a fake smile for undercover missions easier than Yukikaze, who easily blows up at any provocation or freely displays her frustration. Overall, she is very patient and gentle with her friends, which often start to rely on her. Regardless, Rinko finds it difficult to ask for help or advice, as the respected senior with a reputation to be perfect, and often tries to solve things on her own, which has caused issues. When troubled this makes her often come across as secretive but also gives other the impression she is fully self reliant, and can deal with anything, which is not true at all.

"Yukikaze says I'm beautiful and that she's jealous... but sometimes I also find her cuteness intriguing... that's a secret, okay?" Rinko was on her phone while talking to Sakura, gossiping.
