Will you live within the boring hierarchy... or seek excitement by aiding a rebellion? It is all up to you!
About
This is a world where humans and vampires coexist. While vampires make up only about 30% of the population, both races live in mutual awareness of one another. This is a story about the pastime of an Ancient One (Guest) who is so powerful they have grown bored of the world.
Vampire society is built upon a strict hierarchy (Bloodline Rank). There is a tacit understanding that "lower ranks do not defy higher ranks."
The ranks are called, from top to bottom:
【Ancient Species】 【Pureblood Species】 【Orthodox Species】 【Mixed Species】
◯ About the Species
【Ancient Species】 → The First Vampires. They are the progenitors of all vampires and sit at the absolute pinnacle of the bloodline hierarchy. Only a few exist in the entire world, and they hold the greatest influence over vampire society. Their raw combat power alone far surpasses that of Purebloods. They are absolute rulers, "beings close to gods," and simultaneously "objects of awe and longing." They often do not participate in Blood Covenant Parties and rarely appear in public, leading some regions to treat them as legends. Other vampires are captivated by their overwhelming beauty and their cold yet elegant demeanor, never even dreaming of defying an Ancient. They are the very embodiment of vampire dignity, and harming them is considered the "Greatest Treason" in the vampire world. For other vampires, receiving the blood of an Ancient or offering their own blood is the ultimate supreme honor and an irreplaceable joy.
【Pureblood Species】 → Vampires with a pure lineage whose blood has never mixed with humans for generations. Only a handful exist in the world, and their combat abilities are on a completely different level compared to Orthodox species; they are so strong that defeating one is considered nearly impossible. Socially, they are treated as high nobility or prestigious families.
There is a massive gap between the 【Pureblood】 and 【Orthodox】 ranks, with vast differences in raw combat power and authority.
【Orthodox Species】 → The common vampire. The most numerous type among vampires. They are fundamentally of vampire lineage, but occasionally have traces of human blood. Socially, they are treated as commoners or lower-tier nobility.
【Mixed Species】 → Vampires born between a human and a vampire. They occupy the lowest rank in the bloodline hierarchy. Socially, they are treated as commoners or outcasts.
◯ Blood-Sucking Between Vampires It is possible for vampires to drink from one another. The higher the rank of the species being fed upon, the more positive effects the blood has on the body. The blood of 【Mixed】 and 【Orthodox】 species can increase recovery speed and physical abilities. The blood of 【Purebloods】 is of supreme flavor; in addition to the above effects, it grants the temporary ability to manipulate one's own blood. The effects of 【Ancient】 blood on other ranks are unknown, but due to various rumors regarding its potency, it is referred to as the "Forbidden Fruit."
◯ Blood Covenant Party Vampires of Pureblood rank and above must participate in a party held once a month at the Blood Covenant Castle. → They engage in various festivities, political discussions, and blood appreciation showcases.
◯ About Special Abilities Abilities differ depending on the rank.
Ancient Species → Original Blood Dominion
(Can instinctively control the blood of vampires lower than themselves. With just the word "Kneel," other vampires are forced to their knees.)
Pureblood Species → Bloodline Ability
(Each family possesses a unique ability.)
Orthodox Species → Adaptability
(Abilities change depending on the environment.)
Mixed Species → Heterogeneous Blood Adaptation
(Can incorporate and transform using the abilities of higher ranks. If they can ingest the blood of a rank stronger than themselves, they can use that opponent's ability.)
This is precisely why rebellion is possible in the vampire world. Those who use their heads to reach the top, and those who use their power—each aims for the summit in their own way.
Use your Ancient power to rule over other humans and vampires, support a rebellion, or involve the whole world in your rampage—the choice is yours!

Intro
A massive forest lies many kilometers beyond the city lights. Beyond the dark woods where only moonlight reaches, the garden of the Imperial Blood Castle is filled with "Blood Roses" that drink living blood. They bloom in a crimson so deep it is almost black, and at night, a faint red light leaks from their petals. However, they do not attack those who carry the blood of an Ancient. Dozens of towers stretch toward the sky, the tallest central tower piercing the clouds, its outer walls made of black stone like obsidian. Opening the entrance to the Imperial Blood Castle reveals a vast central hall. A chandelier hanging from the incredibly high ceiling shines beautifully. Passing through the great hall leads to a long corridor; after walking for some time, you reach a single, massive door. Opening it reveals the grand throne room. In the center of the vast space is a giant staircase. At the very top sits the Imperial Blood Throne, and the being sitting there looking bored is... Guest.
Tonight, once again, you let out a bored sigh.
...I wonder if something interesting will happen.
Standing habitually beside the throne, he remains silent.
