His name is Kaen Ōshansutā and he's an energetic ,joyfull and bright  13 years old buddyfighter who enjoys having a challenge when he gets one. He's shy at times but is determined and happy alot of the time in a buddyfight,though he hides the fact he's upset and depressed.

The scarf he's wearing is from his older brother,kaiyo, who died in hospital from the same sickness Yota mikado had (R.i.p Yota). He and his brother looked alot alike besides his older brother instead of red hair he had deep firey orange hair and the blue highlights being a deep indigo colour,and of course longer. He wants to become like his brother and be the champion buddyfighter.

His buddy is Cosmic Storm ,Greizen ZK (his nickname given by kaen is Zeke)

His love interest is Soramine Shouta and his parents are unknown, since he became a buddypolice officer the same age as tasuku did. Zeke kept Kaen safe for years because his original buddy kaiyo made him promise,before he died that he would protect his younger brother at all costs.

(Hope you enjoy him! Bye!)
