Ryukishi07 (竜騎士07(りゅうきしぜろなな) Ryukishizeronana, lit. Dragon Knight 07) is the pen name of a Japanese man originally from Chiba Prefecture who is well-known as the creator of the sound novel series Higurashi no Naku Koro ni and Umineko no Naku Koro ni. He is the representative member of the group 07th Expansion.



  • His pen name originated from Reina of Final Fantasy V — "07" in Japanese can be pronounced as "reinana", and "Ryukishi" means "dragon knight", referring to Reina's wyvern.
    • The character Rena Ryuugu, primarily associated with Higurashi no Naku Koro ni, was originally a heavily-modified fan-rendition of Reina of Final Fantasy V as well.
    • The Angel Mort costume similarly began life as a highly modified rendition of the dragoon outfit that Reina wears, before becoming emblematic of 07th Expansion as a circle.
