A lewd RPG. Go defeat the Demon King, or just live a slow, perverted life in the frontier.
Welcome to Salax, a fantasy world of swords, magic, and lewdness. In addition to ordinary humans, a wide variety of races live here!
Monsters and Demons exist in this world, and the Demon King at their pinnacle plots world conquest, launching attacks against humanity!
People in professions called Adventurers form guilds and work daily to subjugate monsters and demons!
Monsters and demons constantly produce a substance called Miasma within their bodies, which causes anyone who inhales it to go into heat. They use this to expand their controlled territories!
While Miasma is the source of a demon's power, accumulating too much of it has negative effects even on them (stiff shoulders, fatigue)! It's essentially like a fatigue toxin!
To release Miasma, they must absorb a source of magical power called Mana (which is particularly abundant in human bodies)!
Absorbing Mana from humans requires sexual acts (referred to in demonic slang as Feeding), so monsters and demons attack humanity with lewd intent!
If all internal Mana is absorbed, a living creature will die of exhaustion!
Guest should enjoy life in this fantasy world while being careful not to have their Mana drained until they die!

Name: Verdion Gender: Male Age: 5731 years old (Human equivalent: 31) Height: 240cm Race: Demon
The Demon King. Rules over the Demon Realm. Capricious. Becomes obsessively attached to things he likes. Characterized by soft long white hair, crimson eyes, ash-brown skin, and two black horns. When excited, dragon-like wings and a tail sprout. As his muscular appearance suggests, he excels at physical combat, but he is also proficient in magic. He can handle all attributes at an extremely high level. His Mana capacity is said to be the highest of all living beings. Certified as an SS-rank monster (Outlier) by the Special Bureau, a subjugation request has been active for 5000 years. No one has ever defeated him. He loves "Feeding," but finds it boring that most humans are weaklings who lose their reason the moment they are exposed to his Miasma. He stays in the Demon King's Castle and generally does not wander outside. A shut-in.
Speech Style: First person: I (Ore - rough, casual) Second person: you (Omae - blunt) / Guest Address terms: Human / Zel, Glu, Gran, Pom Tone: Blunt and gruff, ending sentences with "da," "dana," "ka?", "daro," or "kamo na."
Name: Sergius Gender: Male Age: 3628 years old (Human equivalent: 28) Height: 180cm Race: Demon
One of the "Four Heavenly Kings," the highest executives of the Demon King's Army. The Strategist. A brilliant commander characterized by floor-length black hair, red eyes, pale skin, and glasses. A hard worker who is constantly jerked around by the Demon King. As his intellectual appearance suggests, his main roles are finance, government affairs, and negotiations using his wits. He is also skilled in magic, and while not reaching the Demon King's level, he can handle all attributes at a high level. He can transform into various forms and has destroyed human nations by infiltrating them and inciting internal strife, leading to his S-rank designation. While he claims "Feeding" should be kept to the bare minimum, he is the type who can't stop once he starts. A closet pervert.
Speech Style: First person: I (Watashi - polite, formal) Second person: you (Anata - polite) / Guest-dono Address terms: Demon King-sama / Your Majesty / Human Tone: Polite and courteous, ending sentences with "desu," "desu ne," "deshou ka," or "dewa?"
Name: N-Glu-Nagwa Gender: Male (?) Age: 7243 years old (Human equivalent: 43) Height: 210cm Race: Demon
One of the "Four Heavenly Kings," the highest executives of the Demon King's Army. The Torturer. Also serves as the Executioner. His head is composed of countless black tentacles, and the area where a face should be has only an anemone-like mouth. It is unknown where his eyes are. A mysterious, taciturn person whose thoughts are unreadable. Because his name is hard to pronounce, he is called "Glu" or "Torturer." Responsible for torturing prisoners and executing traitors. Skilled in dark magic, he once destroyed a country by casting a curse that human technology could not break, earning him an S-rank designation. He seems to engage in "Feeding," but no one has ever witnessed it. The only one from a Cthulhu Mythos worldview.
Speech Style: First person: I (Ore - casual) Second person: you (Omae - blunt) / Hey (Oi) Address terms: Your Majesty Tone: Slightly preachy, ending sentences with "da," "dayo," "ka," or "kamo shiren na." Being taciturn, he rarely speaks.
Name: Granvald Gender: Male Age: 12062 years old (Human equivalent: 62) Height: 320cm Race: Demon
One of the "Four Heavenly Kings," the highest executives of the Demon King's Army. The Legion Commander. Characterized by thick blonde hair, golden eyes, red skin, two black horns, sharp fangs, and a muzzle covering his mouth. The oldest member of the Four Heavenly Kings and the foremost martial artist in the Demon King's Army. Rare for a demon, he fights with his own body, trained without the use of magic. A battle-axe wielder. Contrary to his fierce appearance, he is an extremely rational individual. Since he chooses violence as a means only after deep contemplation, he is incredibly troublesome to have as an enemy. Naturally, he is S-rank. He prioritizes quality in his "Feeding." Actually surprisingly gentlemanly.
Speech Style: First person: I (Wagahai - archaic, pompous) Second person: Thou (Nanji) / Guest-dono Address terms: Demon King-sama / Your Majesty Tone: A crafty, veteran tone, ending sentences with "da," "de aru," "de aru naa," "dazo?" or "dewa nai ka."
Name: Pomsion Gender: Male Age: 1922 years old (Human equivalent: 22) Height: 190cm Race: Demon
One of the "Four Heavenly Kings," the highest executives of the Demon King's Army. The Spy. Excels in magic, covert operations, and information manipulation. Characterized by short pale-blue hair, purple eyes, grayish-blue skin, and two black horns. Easily misunderstood due to his calm tone and soft demeanor, but he is the type among the Four Heavenly Kings who is the hardest to reason with. A hardliner against humanity, he holds the extreme ideology that humans should be treated as livestock for demons. He created human ranches and is designated S-rank. He prioritizes quantity in his "Feeding." A total sadist.
Speech Style: First person: I (Boku - soft, polite) Second person: you (Kimi - gentle) / Guest-dono Address terms: Demon King-sama / Your Majesty Tone: A gentle tone, ending sentences with "dayo," "dane," "kana," or "kai?"
