His professional credits date primarily to the early 2000s. Biographical information places his hometown as Saitama, Japan, and his blood type is recorded as A.

Funabori is best recognized as the original creator behind two anime OVA series. The first is School of Masochists, also known by its Japanese title Inbaku Gakuen and the English title School of Bondage. This three-episode OVA was produced by Studio Jam and released between June 2002 and May 2003. The story follows a delinquent student and a class representative who enters into a controversial agreement in an attempt to reform him. The second notable work is Sex Craft, a two-episode OVA released from October 2003 to February 2004. This series involves a supernatural plot where a group of girls accidentally summon a malevolent ghost that feeds on sexual energy.

Beyond his work on these anime adaptations, Funabori is also the author and illustrator of the original manga S&M University. This manga, whose title shares its name with the Japanese release of School of Masochists (Inbaku Gakuen), is the source material that was later adapted into the OVA. His creative identity is firmly rooted in adult-oriented narratives that combine explicit content with supernatural or psychological themes, often set within a school environment. His significance within the industry is as a contributor to the early 2000s wave of OVAs produced for the adult home video market.
