She also acts as Yusuke's assistant and trainer as he starts out his tenure as underworld detective.

She will also join him in the field occasionally; ending up protecting Keiko from insect crazed humans, and in the anime Botan goes with Yusuke and Kuwabara to Tarukane's mansion and acts as team trainer in the Dark Tournament. In the anime television series, Botan is voiced by Sanae Miyuki in Japanese and Cynthia Cranz in English.In the English dubs of the movies she is voiced by Lia Sargent in Yu Yu Hakusho: The Movie and by Veronica Taylor in Yu Yu Hakusho the Movie: Poltergeist Report.

- Flight: As a navigator of the River Styx, she manifests an oar for quick travel through flight, as well as transportation between Human World and Spirit World.
- Spiritual Power: Botan has mild healing abilities, which include slowing down the rate of demonification, but not enough to completely stop or reverse it.
- She is seen using a baseball bat, a mop, and bug spray as weapons during the Maze Castle incident.
- She has displayed the ability to read minds early on in the series.
- One of the earlier chapter covers in the manga implies that she can use the Spirit Gun as she is making the gesture and noise is coming out of the end of the finger, though she never demonstrates this ability. However, she may still be able to use a weaker version of it due to her saying during the Chapter Black Saga that she could blast down walls with the Concentration Ring in order to look for Hiei. This could also imply that anyone who uses spirit energy could use the Concentration Ring to form the Spirit Gun.

- Botan's ability to stay in the physical realm is changed ever so slightly in the anime, when compared to the manga. In the anime, she mentions she has a "human body", implying it's a container which allows her soul to interact, yet when called back to the Spirit Realm, she simply changes her clothes and flies back. In the manga, however, the container body is left behind, immobile while her spirit flies back, only reanimating once she comes back.
- Her appearance is fairly similar to Tana from Fire Emblem: the Sacred Stones
- Coincidentally, Botan's hair is blue.
- Because those of the Reikai age slowly, and as evidenced by her comment during the meeting between the group -minus Hiei- and Koenma, about Sensui, Botan is a new and young grim reaper. She was just starting out a few years before the show began, during Yusuke's early childhood.
- Botan is the first person from Spirit World to accompany a spirit detective:
- Botan was ranked as the seventh most popular female anime character in 1993 Animage Anime Grand Prix, the eighth in 1994, and the eleventh in 1995.
