Naoyuki Sato, better known as 猫叉Master (Nekomata Master, lit. cat crotch Master), is a BEMANI composer who joined Konami in 1999, where he worked for games like the Jikkyou Powerful Pro Yakyuu series and CODED ARMS. Before joining Konami, 猫叉Master was a freelance music composer.
猫叉Master debuted in BEMANI in 2004 with BEYOND THE EARTH from pop'n music 10 CS. He originally wrote songs for the beatmaniaIIDX and pop'n music CS versions, but he eventually moved on to the arcade versions as well, and is now one of the most widespread artists in BEMANI, composing songs for every now-active BEMANI series. His music varies between "worldly" music, drum and bass, and J-Pop. He made his DanceDanceRevolution debut in 2011's DanceDanceRevolution X3 VS 2ndMIX, with Tribe.
猫叉Master is one of the current sound directors of the beatmaniaIIDX series, along with L.E.D., his first sound directing job in a BEMANI game.
