Gen Urobuchi (born December 20, 1972) is a prolific Japanese author in the Visual Novel industry who currently works under nitro+. He is (in)famous for creating dark, tragic settings and plot twists in his stories, in part due to nearly dying in an epidemic when he was younger. (Indeed, as he put it in this interview, the experience gave him "eyesight of the dead".) The work which gave him this fame was Saya no Uta, an H. P. Lovecraft-inspired Visual Novel released under Nitro+. As a result, he has been given the nickname "Urobutcher" by several circles on the internet. That said, he may be trying to break out of this mold; one of his latest projects was a tokusatsu series.note His latest project, Thunderbolt Fantasy, is a puppet TV Series.
