What is Vanguard Princess?
Vanguard Princess is a FULLY FREEWARE Doujin (Homebrew/Indie) 2D fighting game created by a single guy called Sugeno who was released on June 30 2009. The style of the game is a wacky combination between "old skool mechanism" and assist support, all combined with the "all-loved by SRK" loli characters! ANIME!. VP was created on Fighting Maker 2nd, a Japanese "fighting engine" just like MUGEN but with a lot of more support and possibilities.
