OVA
Description
Botan operates as a Spirit World guide, ferrying deceased souls to judgment while defying grim reaper stereotypes through her vibrant appearance and cheerful disposition. She typically displays long cyan hair in a high ponytail, rose-pink eyes in anime adaptations, and blue eyes in the manga; early manga tankōbon covers depict her with blonde hair and green eyes. Her duty attire is a light-pink kimono with a white obi sash, though she adopts human clothing like a Sarayashiki Junior High uniform or biker outfit during the Makai insect infestation. The live-action version features a hime-cut hairstyle with a topknot and white open-toed boots.

Her personality blends genuine helpfulness with occasional clumsiness and an optimistic outlook. Naturally bubbly and talkative, she becomes serious when fulfilling duties. Initially viewing Yusuke Urameshi as an intriguing subject, she evolves into his trusted ally and close friend. She demonstrates loyalty and compassion by comforting Keiko Yukimura and clarifying her non-romantic dynamic with Yusuke to ease jealousy. Despite a tendency toward fear, she exhibits bravery when protecting others.

Her origins, age, and pre-Spirit World background remain undisclosed, with unconfirmed fan theories about a human past.

Her narrative begins by guiding Yusuke after his death, explaining Spirit World mechanics and facilitating his resurrection trial. As his Spirit Detective assistant and Koenma's liaison, she delivers missions, instructs on tools like the Psychic Spyglass and Demon Compass, and transports between realms using her oar. During the Spirit Detective Saga, she suppresses Keiko's demonification post-Hiei's attack, guides Yusuke and Kuwabara against Makai insects, protects Keiko from infected humans, and aids Yukina's rescue. In the Dark Tournament Saga, she initially hides Yusuke's Spirit Detective identity from Keiko before revealing it, escorts Keiko, Shizuru, and Atsuko Urameshi to the tournament as team coach, and ferries Genkai's soul. The Chapter Black Saga sees her briefing Yusuke on new threats, collaborating with Kuwabara and Kurama to rescue him from Kido's group, negotiating Hiei's probation reduction, and enduring capture in Kaito's territory before rescue. Post-Sensui's defeat, she reports to King Enma and confirms Yusuke's survival to Keiko. She accompanies Koenma to observe the Demon World Tournament in the Three Kings Saga and delivers Shunjun's case message to Yusuke in the "All or Nothing" OVA.

Her relationship with Yusuke shifts from guide to confidante and friend. She shares a particularly close bond with Kazuma Kuwabara, emphasized when Yusuke communicates emotionally with him—a gesture reserved for closest allies. She maintains a professional, loyal rapport with Koenma as his messenger and operative, while supporting Kurama, Hiei, and other team members.

Lacking direct offensive spirit powers, she possesses heightened spirit awareness and sufficient energy to operate Spirit World tools. Her limited healing capabilities pause demonic transformations. In combat, she wields physical objects like her oar, baseball bat, mop, or bug spray. She inhabits a physical human body to interact seamlessly in the Human World.

The live-action adaptation preserves her core role as the guide informing Yusuke of his death and Koenma's resurrection offer, portrayed by Kotone Furukawa.
