the art in this game is top notch and i enjoyed the story and characters. my only issue is they reuse some of the same cgs and just change the background which feels a little cheap with how little cgs there already are in this game. there are also random scenes were the screen just turns black and it describes a sex scene with no cgs or images at all which feels very cheap and i have never experience that in any sims ive played in the past.

About This Game
A NSFW Yaoi / Bara Visual Novel! WITH FULL VOICE ACTING!

Samurai Asano was betrayed by his daimyo master, the warlord Sakuna, who steals his ancestral onsen. Asano vows to get revenge by ruining the onsen!
When Sakuna's daughter Mina takes over the onsen, she unwittingly awakens four oni who are trapped there. The grateful oni will protect Mina and thwart Asano--but then they learn the sexy samurai is the key to their freedom!
According to legend, the only way an oni can exit the onsen is by 'getting love' from a member of the original family. The oni take the word ‘love’ to mean the physical kind!

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?

User Reviews
I'm usually not such a harsh critic but I've been following Y Press Games for years, buying every game they come out with. The art in this is very beautiful but I couldn't stand the story. It felt like the writing was rushed, there were several typos or weirdly phrased sentences, and missing scenes (I know its because of the recent credit card drama and trying to prevent the game getting censored, but it does make it feel incomplete). It's more of a Japanese setting too so seeing the very Scottish Oni was off putting. I couldn't stand his route honestly.
