Hiroyuki is a male Japanese manga creator from Nerima, Tokyo, Japan. He is notable for the creation of the four-panel comic strip manga Dōjin Work which is the first of his works to be adapted into an anime. Hiroyuki is well-known for the creation of many dōjinshi based on the Type-Moon visual novels Tsukihime and Fate/stay night.
He has won online fame due to his Tsukihime doujins about Len. The truth is that he's a talentless hack who draws great facial expressions, but he's a copypasta maniac and receives most of his inspiration while on the loo.
His older sister, Kouji Megumi, is also a manga artist.
