Kayin is a friend of Eiji Shinjo and is a bounty hunter, going by the name of Storm. He was trained in sword-fighting along with Eiji by Eiji's older brother Sho, until he suddenly disappeared. Kayin then entered the first Toshinden tournament to avenge his father's recent death, who he learned had been killed by a participant who won the previous tournament. He eventually learned that Sho was the perpetrator and his friendship with Eiji was nearly shattered because of this.

Kayin was then forced to enter the second tournament after his adoptive daughter, Naru, was kidnapped by the Secret Society. At the end of the event, he managed to help bring down the fall of the Secret Society and rescue Naru. However, he then discovered that they were being targeted by the Organization. He participated in the third tournament hosted by it and managed to help destroy the Organization. However, he realized that Naru would always be in danger because of him and he decided to leave her in a housing institute. He handed down his Excalibur sword to her and then disappeared.

To state the obvious, Kayin is definitely what you'd call the "Ken" of the Toshinden series... as Eiji is clearly "the Ryu". Kayin had some pretty cool moves that set him apart from Eiji and other characters in the Toshinden series. His original outfit is cool & classy and his personality is pretty defined as well... considering what they had to work with at the time.
