Ganryu[a] is a 1999 side-scrolling hack and slash action-platform arcade video game developed and originally published by Visco Corporation exclusively for the Neo Geo MVS.

[2][3] In the game, players assume the role of either Musashi or Suzume on a journey to defeat a resurrected Kojirō and his legion of evil ninjas and monsters terrorizing Kyoto.

A month has passed since the defeat of Kojirō at the hands of Musashi, who is planning to meet in Kyoto with his love, Otsu, who is joined by her young sister Suzume, a kunoichi from the Iga clan.

[1] On their venture, the duo faces a number of ninjas as well as monsters and eventually find the author responsible for all the occurring kidnappings in Kyoto; Sasaki "Ganryū" Kojirō, who has a scar on his forehead and had risen from death reincarnating as a vengeful demonic demigod embedded with rage and evil known as Chaos, obtaining a power far beyond his imaginations and challenges both Musashi and Suzume to a final duel in Ganryū-jima.

[1][5] Although it was never originally ported to the Neo Geo AES, an officially endorsed conversion of the game by independent developer and publisher JoshProd was released for the console in June 2016.
