   Summary

   The moon shone on raven black hair for the first time in 9 years.
   The light scattered gracefully.

   The raven himself ran, in fear of everything he'd ever known.
   Only to be swept into a family and retaught everything he's ever known for the near decade he's been alive.

   12 years later, he journeys through expanding friend groups, drama, and relationships blooming - something he never would have expected considering his tragedy.

   Meet Iguro Obanai, a boy who went through one of the worst childhoods and yet managed to make one of the best lives for himself amidst his trauma and psychological struggles.
   All with an ivory snake curled up around his neck.
