Ryukishi07 (竜騎士07 Ryūkishi Zero Nana?, born November 19, 1973) is the pen name of a Japanese author and artist well known as the creator of the visual novel franchises Higurashi no Naku Koro ni and Umineko no Naku Koro ni. He is the representative member of 07th Expansion. Ryukishi07's writing has been described as alternating between "macabre scenes and schoolboy humor". He has said that, "a story should be like a roller coaster. That is to say before writing a really cruel scene, I have to lift the people's spirits, for example, with a fun scene... Before writing a scene of pure despair, we must go through scenes of hope. And indeed, when I write, all of this amuses me very much." His illustration style is recognizable from the large hands he draws on people.
Ryukishi07, who was interested in video games, anime, and manga, studied at a vocational school that specialized in art. During that time, he wrote doujinshi. During his time in college, he tried to write manga and novels, but he came to realize that "No matter your passion for something, without skill, you can never make it as a professional." One day, he met with a colleague from a theatre troupe, and he was inspired to write a play called "The Hinamizawa Bus Stop" (雛見沢停留所 Hinamizawa Teiryūjo?) which he submitted to a contest that he later lost.
After graduating from the vocational school, he dreamed of becoming a video game developer, so he focused on finding a job at a video game manufacturer. However, none of his attempts at this were successful. Reluctantly, he took up a position at a menswear store, but after a few months, he tentatively took up an offer for a civil service position based on the civil service test that he had taken during the job search.
