Riku

Riku is the youngest child in the Fallonchaster family, born with albinism and an incurable unknown disease. His parents took him to the doctors, but it was to no avail. However, one day Riku's mother took him to a strange man who called himself Dr. Eren Gran. This man treated Riku for several months, and then suddenly kidnapped him. In the lab, Dr. Gran cured him of death by turning him into a mutant. However, as Riku changed, he also lost some of his human traits. Over time, he forgot how to speak humanly and now makes only purring, wheezing, chirping sounds. In the same way, his intelligence was reduced to the level of an animal. He wears clothes without really thinking about why they are needed. And his main priority is either food or sweets or something else. Absolutely legal.
