- 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.
