Very good doujin fighting game based on the classic visual novels of Nitro+ (Phantom of Inferno, Vampirdzhija Vjedogonia, Kikokugai: The Cyber Slayer, "Hello, world."; Saya no Uta; Angelos Armas; Hanachirasu; Dra KoI; Gekko no Carnevale; Kishin Hishou Demonbane) and had the participation of Saber from Fate/Stay Night.
 
The gameplay is very good, the soundtrack is very good, and the gameplay is simple and fun to play. The game has a lot of fan service from the visual novels of Nitro+ too, so if you are a fan of Nitro+, I recommend this game even for that to enjoy the game even more and because of the game as a whole.
 
The only two criticisms I have are that the location of the buttons is not very well implemented on the keyboard in the default configuration and that it does not have a training mode, but it is not something that spoils the game as a whole.
 
Even so, I still recommend this game for doujin fighting game fans, for those who want to know more about the works of Nitro+ because of this game, and for enthusiasts of Nitro+.
