Yes folks! The cute comedic parody anime Lucky Star has done it again! They've parodied 4 of the SFIV cast namely Ryu,Ken,Guile and C.Viper.

The main character Konata plays Guile, probably because she defeated him in the parody anime. The sisters plays Ryu and Ken. Kagami the ponytailed girl plays Ryu and Tsukasa the short haired one plays Ken. Miyuki is PERFECT for C.Viper's parody role since she has glassess, a big CUP size among the girls and has long hair too. I dunno what the Japanese characters says, but clearly the SFIV there on the uper right is Street Fighter IV.

Here's the original parody in the anime where Konata beats up a "FOREIGNER" (Guile).
