Shiro-Ya-Ku is the third member of a trio of Ya-Ku bird wyverns, alongside Diru-Ya-Ku and Kutsu-Ya-Ku. Reminiscent to cranes in appearance, it lives in snowy regions. Shiro-Ya-Ku is territorial, like its relatives, but is the least aggressive of the three. When tamed, Shiro-Ya-Ku will function as a glass canon. Its attacks are extremely quick and relentless, having different damage multipliers depending on the body part hit, and a bleeding debuff. However, it is the smallest of the trio, also making it not very durable. It will also have a mechanic around its extremely dense coat of feathers. It will give insulation to its riders in cold environments, but in standard and hot conditions will cause its rider to overheat. This can be mitigated by your Shiro-Ya-Ku doing a preening move. The feathers' ability to store heat could also be an offensive advantage, as it will be able to do a "heatwave" move, were nearby enemies will be slowed down and start to overheat.
