Yo-kai Medallium biography
"He was born into a prominent rakugo family, but he felt that rakugo was not his talent, so he left home and enrolled in Y-School. He was admitted to the school, because he had the same YSP standards as his friend from elementary school, Jinpei Jiba."


Sandayu Koma (Japanese: 小間 サン太夫 Koma Sandayuu) is one of the main characters in the Y School Heroes series.

He attends a boarding school called Y-Academy as a first-year student specializing in YSP (Yo-kai Special Power) and owns a YSP Watch that can make him transform into Little Kommander with Komadillo.
