This is a heavily headcanonized version of Koashura (YYH: The Golden Seal). So read at your own discretion being aware of this!

• Koashura's full name: Trishira Ravana Kulīrā
• Crown Prince of Kuliradaha, one of the many factions of the Asura Kingdom
• Birthdate: July 20th, 1324
• Adult form info: As tall as Koenma's (so around 6'3"/1.90 cm), his hair, instead of being tied upwards like his toddler form, it's tied in a lower ponytail with golden braids. He sports a similar uniform to the one he wears in his toddler form but wears black martial arts pants, purple and indigo scarf reminding his crab form and red boots with black zipper.
• This Koashura comes from an AU where The Golden Seal didn't happen, so some things may be different
