Vanguard Princess (ヴァンガードプリンセス Vangaado Purinsesu), also known as Vanguard Princess: Senjin no Himegimi (ヴァンガードプリンセス 先陣の姫君) is a Japanese freeware dōjin 2D fighting game for Windows, developed by a single programmer and illustrator called Tomoaki Sugeno, nicknamed Suge9. Vanguard Princess was fully developed by Tomoaki Sugeno (or Suge9), an ex-Capcom sprite designer who worked in games like Resident Evil 3: Nemesis and made character sprites for The King of Fighters EX: Neo Blood. Sugeno designed and illustrated the game by himself, but the music was taken from "nash music library", a GNU library of songs. Sugeno also resorted to voice actors for recording the voices for all the characters. Source: Wikipedia, "Vanguard Princess", available under the CC-BY-SA License.
