Although she named herself after Ryoko Hakubi, Ryoko Balta is hardly as bloodthirsty as she is rumored to be. Even though she was a member of the dreaded Daluma pirate guild, Ryoko Balta is the most educated and cultured pirate there was. She is well-versed in many customs from other planets, including the Japanese Tea Ceremony. And her beauty is such that some male Galaxy Police members would be willing to desert their posts in order to join her (it is rumored that there are many "Ryoko Balta Fan Clubs" in some G.P. posts).

Within the pirate guild, however, Ryoko had few friends, and was hostile to Tarant Shank, the guild's vilest member. However, she is also a great friend of another of the guild's members, Kyo Komachi.

Ryoko Balta is also a shape-shifter, and she often used this power to infiltrate Galaxy Police posts to gain information. One of her favorite forms is that of Erma, a Wau Galaxy Police clerk who works for Airi Masaki, the head of the G.P.'s Jurai office and the grandmother of Tenchi Masaki.
