A product of the Animal Hamaguchi Gym, K-ness debuted with Michinoku Pro, in the same match as Gamma. He spent some time on the indy scene, before debuting in Toryumon as the face painted vampire MAKOTO. He lost a loser leaves Toryumon match at World 2000, marking the end of his maskless career. He returned as the masked Darkness Dragon, the dark antagonist to Dragon Kid. They feuded for several years, culminating in a mask match in 2002. He lost his mask, but would soon put on a new one, becoming K-ness. Injuries have plagued him for most of his career, frequently putting an end to any momentum he has gained. After some time as a background player, he began a resurgence in 2013. After his first ever attempt on the Open the Dream Gate, he returned full time to the front lines.
