About the 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?

Monster Lover: Ambrosilas OUT NOW!
Monster Lover 2 Out Now! Meet Ambrosilas! Big news! The sequel to Monster Lover: Balasque is our now! Check out Monster Lover: Ambrosilas! https://clan.fastly.steamstatic.com/images/35059450/b2a53246d4424480dc9447f971f958ee146abe83.png He's a Failure of a Yakuza. He's an Arcane Murder Genie - Can They Find Love? https://clan.fastly.steamstatic.com/images/35059450/3dacd4004936daef61dd6929e9101b659fb68c41.png Our main character (you name him) has been a screw-up his entire life. That's what led him to his life of crime. His screw-ups now have higher stakes, and that's where the demon Ambrosilas comes in. Can this sexy murder genie get him out of his latest life or death blunder? Ambrosilas has one mission: kill bad people to make the world a better place. He's not about to be the puppet of a worthless criminal! The rules are set in stone: Give him someone worthy of death to kill or he kills the one who summoned him. But what does our main character do when his target isn't worthy of death? He really didn't think this through...as per usual. He needs Ambrosila's help if he wants to stay alive, but the demon isn't going out of his way for a criminal. "But you said I was at least nice to look at?" https://clan.fastly.steamstatic.com/images/35059450/9abf87292adf7dac2e829d384b461233cd72510e.png It's true, his criminal master is a handsome mortal, and the more he gets to know him the more he realizes he might not be so worthless after all. Perhaps he can help him...for a price. Our main character is surprised at how attracted he is to Ambrosilas. He's got no one else to turn to...and he doesn't mind when he's pulled into the demon's arms. Monster Lover 2: Ambrosilas is the visual novel sequel to Monster Lover: Balasque! New human, new demon, and loads of monster loving!
