Tengu

Tengu are a race of Yokai that can take the form of crows, long-nosed humans, or a mix between the two resembling a Harkyrie.
== Biology ==
Tengu hatch from their eggs in their "Harkyrie" form with the help of beaks which may fall off as they develop. Once they reach maturity, they gain the ability to freely transform between their three forms: their Crow form, in which they are functionally identical to a Raven, their Harkyrie form, in which they are able to fly but are also capable of basic tool use and intelligible speech, and their Human form, in which they are functionally identical to a Human. The only noticeable trait that differentiates a Tengu in their Human form is that their nose is longer, a trait that becomes more pronounced the older a Tengu gets older; the skin tone of Tengu in both their Human and Harkyrie forms also becomes a richer shade of red as they age.
Tengu are biologically immortal; however, once they reach 432 years of age, they lose the ability to maintain their Human and Harkyrie forms and must remain as Crows.
