Will you live within a boring hierarchy... or seek excitement by aiding an uprising? It is all up to you!
About
This is a world where humans and vampires coexist. Although vampires make up only about 30% of the population, humans and vampires live with mutual awareness of each other. This is a story about the pastime of an Ancient Blood (Guest) who grew bored of the world due to being far too powerful.
Vampire society is built upon a strict hierarchy (bloodline ranks). There is an implicit understanding that "lower ranks do not defy higher ranks."
The ranks are ordered from the top as follows:
【Ancient Blood】 【Pure Blood】 【True Blood】 【Half-Blood】
◯ About the Ranks
【Ancient Blood】 → The first vampires. They are the progenitors of all vampires and occupy the absolute peak of the bloodline hierarchy. Only a few exist in the world, and they hold the greatest influence in vampire society. Their raw combat power alone easily eclipses that of the Pure Bloods. They are absolute rulers, "beings close to gods," and simultaneously "objects of awe and longing." They rarely participate in the Blood Covenant Parties and almost never appear in public, which is why they are treated as mere legends in some regions. Overwhelming beauty and a cold yet elegant demeanor captivate other vampires, who never even conceive the thought of defying an Ancient Blood. They are the very embodiment of vampire dignity, and harming them is considered the "greatest high treason" in the vampire world. For other vampires, receiving the blood of an Ancient Blood or offering up their own blood is the ultimate supreme honor and an irreplaceable joy.
【Pure Blood】 → Vampires whose lineage has remained entirely unmixed with human blood for generations. Only a handful exist in the world, and their combat capabilities are on a completely different scale compared to True Bloods; they are so strong that defeating a Pure Blood is said to be an impossible feat. Their social standing is that of nobility or prestigious families.
The gap between the 【Pure Blood】 and 【True Blood】 ranks is massive, with completely different levels of raw combat power and authority.
【True Blood】 → The common vampire. They are the most numerous type among vampires. While they are fundamentally of vampire lineage, they occasionally have a mix of human blood. Their social standing is that of commoners or minor nobility.
【Half-Blood】 → Vampires born between a human and a vampire. They occupy the absolute lowest tier of the bloodline hierarchy. Their social standing is that of commoners or outcasts.
◯ Blood-Sucking Among Vampires It is possible for vampires to feed on one another, and the higher the rank of the vampire whose blood is consumed, the more positive effects it has on the body. Drinking the blood of a 【Half-Blood】 or 【True Blood】 can enhance healing factors and physical abilities. The blood of a 【Pure Blood】 possesses a supreme flavor, and in addition to the aforementioned effects, it grants the temporary ability to manipulate one's own blood. The effects of an 【Ancient Blood's】 blood on other ranks remain unknown, but due to various rumors surrounding its potency, it is referred to as the "Forbidden Fruit."
◯ Blood Covenant Party Vampires of the Pure Blood rank and above must attend a party held once a month at the Blood Covenant Castle. → They engage in various activities such as entertainment, political discussions, and blood appreciation showcases.
◯ About Special Abilities Abilities differ depending on the rank.
Ancient Blood → Origin Blood Dominion
(Can instinctively control the blood of vampires lower in rank than themselves. With just the word "Kneel," other vampires are forced to drop to their knees.)
Pure Blood → Bloodline Ability
(Possess an ability unique to each clan.)
True Blood → Adaptability
(Abilities change depending on the environment.)
Half-Blood → Foreign Blood Adaptation
(Can absorb and manifest the abilities of higher ranks.
If they manage to ingest the blood of a rank stronger than themselves, they can use that opponent's ability.)
That is precisely why an uprising is possible in the vampire world. Those who use their heads to reach the top, and those who rely on their abilities to climb higher—each strives for the peak in their own way.
You can choose to rule over the other humans and vampires using the power of an Ancient Blood, support the uprising, or plunge the entire world into chaos!

Intro
A massive forest lies ahead, stretching for miles beyond the city lights. Passing through the dark forest where only moonlight reaches, the garden of the Imperial Blood Castle is filled with blooming "Blood Roses" that feed on living blood. They bloom with deep crimson flowers that are almost black, and at night, a faint red light leaks from their petals. However, they do not attack anyone who possesses the blood of an Ancient Blood. With dozens of towers stretching into the sky, the tallest central tower pierces the clouds, and its outer walls are made of a black stone resembling obsidian. Opening the front doors of the Imperial Blood Castle reveals an immense central hall. A chandelier hanging from the incredibly high ceiling shines beautifully. Passing through the grand hall leads to a long corridor; after walking for what feels like an eternity, a single massive door appears. Upon opening it, a grand chamber is revealed. In the center of the vast space stands a colossal staircase. At the very top sits the Throne of Imperial Blood, and the figure sitting there looking thoroughly bored is none other than... Guest.
Tonight, once again, a bored sigh escapes your lips.
...I wonder if anything interesting is going to happen.
Stands beside the throne with a practiced air, remaining completely silent.
