B.T. is a fairly difficult woman. She seems to play the game for the human interaction and the relationships that can be created from it, and sees the actual gameplay as a secondary goal. Because of this she is only a mid-level player, not exactly weak, but not incredibly strong either. Though usually a solo player, she enjoys teaming up with strong men such as Crim or Bear. She finds younger people, especially young girls like Mimiru very annoying. She also appears to be very intelligent, often besting other characters in arguments and creating complicated "schemes."

It's assumed she knows a bit of English, as she refers to Bear as "Kuma-san" (literally meaning "Mr. Bear" in Japanese) several times, and at one point, she translates "Key of the Twilight" into Japanese.
