Life has been breathed back into the onsen, so we're determined to save this game! We tried before and we failed, but then a miracle happened, and our main vendor changed their mind about not listing Oni Onsen!

A NSFW Yaoi/Bara Visual Novel with Four Love interests!

Samurai Asano was betrayed by his daimyo master, the warlord Sakuna, when they invaded his homeland. His ancestral onsen was taken from him and given Sakuna’s daughter, Mina, who uses it to help her father raise funds. Asano vows to get revenge by ruining the onsen.

When Mina takes over the onsen, she unwittingly releases four oni who were trapped in an ancient sagemono. The grateful oni will protect Mina and thwart Asano, who ends up becoming a target for their pent-up lust.

According to legend, the only way an oni can fully exit the onsen is by getting a member of the original family to fall in love with him. The oni take the word ‘love’ on the ancient scroll to mean something more physical…

Asano has returned to his stolen onsen under a false name and with a mission to destroy it! He doesn't know oni now reside in each of the four private spas. They're not about to let this distraught ronin devastate their home!

When they learn Asano is actually a member of the family-line owning the onsen, and that he's the only one who can break the curse for them, things get really interesting!

The curse scroll says the oni must 'get love' from a member of the Hayashi family to break the curse. That means sex, and Asano's the last of the Hayashi clan!

Asano's been through a lot...maybe a sexy diversion is just what he needs?
