Sengoku Ace was the first game by Psikyo and was designed by Shin Nakamura, the creator of Aero Fighters (Sonic Wings) and the company's founder. It was followed by two sequels, Sengoku Blade: Sengoku Ace Episode II (1996) and Sengoku Cannon: Sengoku Ace Episode III (2004).
The story of Sengoku Ace resolves around the six Feudal Japan characters sent on a mission to stop an evil pagan cult (Christian heretics) and rescue the shogun's kidnapped daughter, princess Tsukihime (Moon Princess), before she can be used as a sacrifice to resurrect a demon god. The game features 21 endings, different for various characters (including the 2-player pairings).
- Flush (Flash) / Ayin (Shine-Ain) / Kain (せんこうのャイン) - a 25-year old, one-eyed, blonde samurai flying a J-9, who is looking for his sister Asuka. He is voiced by Hisao Egawa.
- Gen / Gennai (アイン) - a 77-year old scientist with a small robot assistant named Ranmaru, who flies a small, agile "Super Fighter" plane. He is voiced by Daisuke Gōri.
- Jane Hayate (はやてのジェーン) - a 21-year old blonde and blue-eyed beautiful female ninja who flies a glider. She is voiced by Hiroko Emori.
- Kenno (Kenno Maru) / Kenoumaru / Ohmaru (犬王丸) - a "super genius dog" flying a high-tech F-15 aircraft (according to some of his team play endings, really a young man sealed in a dog form).
- Miko / Koyori (Koyori Togashi) (富樫こより) - a 17-year old miko priestess with a fascination for money, who flies a biplane. In Sengoku Ace, Koyori is still very young and tomboyish. She is also voiced by Hiroko Emori.
- Tengai (Tengai Kano) (ターボ坊主 天外) - a 50-year old Japanese Buddhist wandering monk who flies a bizarre bird-like plane. He is also voiced by Daisuke Gōri.
In December 2004 the game was ported to PlayStation 2 as part of the Psikyo Shooting Collection Vol. 2: Sengoku Ace & Sengoku Blade by Taito and 505 Games; it also was re-released one year later as a budget-range title.
