Oharu has ankle-length dark-purple hair that has two hair strands sticking up where it resembles animal ears with medium-length hair strands hanging on either side, dark-purple eyes and large breasts that tend to bounce a lot. She wears a pink kimono.
Oharu has shown a lot of respect and care for Jinbei, even calling him "sama". Ever since Jinbei saved her from the Roof Prison Spider, she's held strong feelings for him. Though she seems to be insecure in herself as when Jinbei's father, Genjuurou, gave his blessing to let her marry him, Oharu became extremely flustered. While Jinbei is oblivious to Oharu's (rather obvious) crush, he has nonetheless become especially protective of her.
- The name Oharu means "spring" (春).
- Oharu's three measurements are B94, W58, and H88.
- Oharu's appearances are the main source of fanservice for the series. Also, a recurring theme for her is becoming quite clumsy around Jinbei Tsukishima, often falling onto him and pressing her breasts into his face as a result.
