Hot Stuff feat. KM-MARKIT is the fifteenth single by Japanese singer-songwriter Kumi Koda. It charted No. 10 on the Oricon charts and remained on the charts for ten weeks.^[1] The single was limited to 30,000 copies and has since sold over 29,000.^[2] The single was only released in CD+DVD format, with the CD containing four songs and the DVD carrying three videos, along with the making video of the title track.

"Hot Stuff" featured Japanese rapper KM-MARKIT, who was part of the Urbarian Gym (UBG) and, at the time, was making a debut as a solo artist under the Pony Canyon label.

The single contained three b-sides, all which were remixes. It also carried the "Kakuhen Musou Tenshou" (確変無想転生) remix for "Hot Stuff," which featured both KM-MARKIT and underground rapper UZI. The song was used in April 2005 as the ending theme to TX's television program Ryuha-R (流派－Ｒ / School-R).^[3] The song's remix was originally released as a bonus track on her secret album.

The DVD carried the music video to "Hot Stuff," along with the "Thanks to MAM & GRAMMA" version of "Trust You" and a live clip of "Selfish." The original video to "Trust You" was on her DVD girls ~Selfish~, as well as the corresponding album, secret. A dance version to "Hot Stuff" was later released on the DVD of her third compilation album, Best ~Bounce & Lovers~, though this version omitted KM-MARKIT's appearance in the video.^[4]

Kumi would collaborate again with KM-MARKIT for the song "Rainy Day," which was released on his debut album, Vivid, though he was under the Pony Canyon label.^[5] Vivid also harbored the music video for the song when placed into a DVD player.^[6]

Along with featuring rapper KM-MARKIT, the music video to Hot Stuff carried a street fighting theme, along with underground hip-hop dancing themes.

The video opens with street fighting, but is predominantly centered around Kumi's dance crew battling the rival crew, which is hinted to be KM-MARKIT's, though the rapper is not featured in the dancing scenes. The music video was heavily inspired by the 2003 Chris Stokes film You Got Served, which had opened No. 1 at the box office upon its release and featured R&B rappers Marques Houston and Omari "Omarion" Grandberry.^[7]

A dance version was later released on her third compilation album Best ~Bounce & Lovers~. This edition omitted the street fighting scenes and KM-MARKIT's physical appearance, instead only focusing on the dance battle.
