In fact one can simply go to the original devs website here - and as you can see the game is available on his website for anyone. For one thing, I think the fact should be mentioned that the original Japanese release of Vanguard Princess was released entirely as freeware by the original developer Suge9.

I am not the sort of person to normally do this, but I just generally have a problem when a game publisher tries to screw some of the fan base by some unscrupulous methods. And this new character that's been teased since 2012 (I think, it's been a long ass time.) In the meantime, I've been sitting here hankering for Vanguard Princess Prime. The last update to be released was the official Windows port with English translations and what not. It's definitely one of the most overlooked fighters in my opinion, and the one that needs a community the most. Parrying, Assists, back dash, and unique hit stuns/responses lend into a huge variety of situational depth and setups. To the inexperienced it might seem simple and similar to ST, but to the more experienced and creative, that game's depth is off the charts. I honestly rank it up there with Garou and 3S.

A unique 2v2 fighter brought to you by Suge9 with glamorous visuals, an all female cast, unique movesets, and an intricate fighting system that is reminiscent of past games filled with depth. One of my favorite fighting games since 2008 has been Vanguard Princess, I love the fuck outta that game.
