士郎子
A character from the [[Fate/stay night]] doujin series "Heaven's Failure", by [[Limit Break]]. In the series, Limit Break creates her using a fusion of the mindset of [[Emiya Shirou]] and the body of [[Illyasviel von Einzbern]].

Effectively a [[Genderswap|genderswapped]] version of [[Emiya Shirou]], though the tag refers only to Limit Break's character and not genderswapped Shirou images in general.
