Born in Boston, USA in 1999. His real name is Satoru Motoyama. He was born small and grew up slowly as a low birth weight baby with mild hearing loss. He was later diagnosed with autism spectrum disorder and intellectual disability. He discovered watercolor painting at a summer camp at the age of 10. Since then, he has been painting one picture a day, and his style has been gradually changing. As a member of the local family support group Boston Special Needs (BSN), he has exhibited his work at numerous art fairs.
