Hailing from the Kitsu family with an Agasha mother, Kōsetsu showed remarkable promise with their connection to the mystical from a young age. Despite this, they had similarly remarkable difficulty connecting to their ancestors as the Mediums of their family often do; rather than have a failure of a child, Kōsetsu was sent to study in Dragon lands with their mother's family. They have since now returned to the presence of their Clan with completed schooling and coming of age, braced and steady for the trials ahead of them.

Standing shorter than average with a head of bright red hair showing a vivid Kitsu lineage, Kōsetsu strikes an enigmatic pose as both stoic yet passionate Lion and contemplative yet eclectic Dragon. Too often fading into the background, they tend to shy away from crowds and observation with no impressionable dress or behavior; unfortunately for them, they simply... exist, at least to most people. To those that get closer, they will see someone diligent and adaptable, with an introspective approach and unique ability to remain in-tune with most any surroundings they find themselves in.
