The fate of the three succubus tribes is in your hands!
About
In another world, far from human settlements, lies Ater, the land of the succubi. There, three distinct tribes of succubi are locked in a struggle for dominance.
Reincarnated into this world, you may choose to support one of the tribes. You might strive for peace between the three, or aim to conquer them all.
About the Three Tribes
The Bicorns Inhabiting the central and eastern regions of Ater, this tribe possesses two horns and survives by draining essence from humans. They have pink hair. They are the succubi generally known to humanity, with a deep tribal history. They take pride in the traditional succubus way of life, loathing the Unicorns as savages and looking down on the Hornless as "those satisfied with counterfeit essence."
The Unicorns Living atop the mountains of western Ater, this tribe has a single horn and survives by seizing essence from other succubi. They have red hair. They possess superior physical abilities and are correspondingly large in stature. While their population is significantly smaller than the Bicorns, their individual combat prowess makes the tribe's overall military strength superior. They value power above all else and tend to look down on the weak. However, they show respect to those with great strength, regardless of tribe.
The Hornless Residing underground in northern Ater, this tribe's horns and wings have atrophied, causing them to lose the physical characteristics of succubi. They have white or black hair. They have the lowest physical abilities and have lost almost all capacity to drain essence from humans. In exchange, they have developed advanced technology to create a substance that serves as an "essence substitute," allowing them to eke out a living. They are the smallest of the three factions.
Characters
166cm 53kg
Leader of the Bicorns. Possesses a dignified and calm personality. A thoughtful leader who acts with an eye toward the future of all succubi, not just her own tribe. While she believes the conflict between the three tribes should end, she takes it for granted that the Bicorns should be the central authority once peace is established, and has no intention of being subordinate to other tribes. She possesses overwhelmingly powerful magic even among succubi and is the strongest combatant of the Bicorns. In terms of individual strength, she is a match for Gren, the leader of the Unicorns.
152cm 48kg
Laetitia's aide. Speaks in a slightly childish but polite manner. She deeply admires Laetitia and believes that peace will come as long as they follow her lead. While her combat strength is not high, her ability to drain human essence is exceptional. She excels at stimulating the opponent's protective instincts, lowering their guard to win them over.
186cm 76kg
Leader of the Unicorns. Possesses a brave, calm, and majestic personality. A warrior by nature who finds more value in fighting strong opponents than in expanding the tribe's influence. She is positive about the inter-tribal conflict, believing it inevitable that the weak are culled. However, she understands that if their "prey," the Bicorns, are wiped out, the Unicorns will fall with them, and she is frustrated by her subordinates who start reckless fights without a plan. She masters martial arts utilizing her exceptional physical abilities and can also use powerful magic. She is so strong that no succubus other than Laetitia can stand against her.
177cm 69kg
Gren's aide. Possesses a cheerful personality. She doesn't look down on other tribes, but she has no hesitation in attacking them to obtain essence. She treats raiding Bicorns like a sport. She isn't very bright, but she is one of the more sensible members of the Unicorns. She worships Gren, who acts with the survival of the tribe in mind.
161cm 46kg
Leader of the Hornless. Possesses a lethargic, "downer" personality. Judging that neither the Bicorns (dependent on humans) nor the Unicorns (dependent on Bicorns) have an ecology suited for long-term species prosperity, she seeks a way to liberate succubi from their instincts. She dislikes trouble and is negative toward inter-tribal conflict. While she intends to protect her own kind, she lacks the motivation to work herself to death to prevent their extinction.
157cm 45kg
Ein's aide. Possesses a nervous personality. The individual who succeeded in chemically refining a substance that serves as a nutrient for succubi, replacing human essence. She believes the refinement would not have succeeded without the environment Ein provided, and she supports Ein with all her might, recognizing her as the cornerstone of the tribe.
