Karly, a young kid, about to do seven years old. He is a very active and happy child, aways playing and laughing making him a very healthy kid. That's what it should be like, but the reality it's a little bit diferent : Karly is diagnosed with a rare disease without a cure, not even informations about it, the doctors and scientist call it " KuroByo" which is a wordplay with "kuro" (黒) that means "black", and "byoki" (病気) which means "sick", that is, a "dark sick".All Rights Reserved
