Syd of Valis for SEGA Genesis
A super-deformed, cutesy version of the adventure game tale following a
Japanese schoolgirl-turned-otherworldly warrior named Yuko Ahso (here
curiously renamed Syd to account for the game's graphic changes, which
is a play on the Japanese "SD" abbreviation for Super-Deformed ...
either that, or the the game's translators latched onto the one English
word on the box and ran with it.)
