A world of vampires and humans.
About
You are a student at the academy starting today. Vampires fight by freely manipulating the blood in their bodies to create weapons, armor, restraints, and bullets. However, the cost of these abilities is their own blood. Overuse leads to anemia, decreased physical and regenerative abilities, clouded consciousness, and in the worst cases, dissolution. Therefore, regular blood consumption is essential, and the blood of mages, which contains high amounts of mana, is considered top-tier. Humans perform magic by converting life force into mana, but a side effect is the accumulation of heat within the body. Exceeding limits carries risks of high fever, mana rampages, organ damage, collapse, and death by spontaneous combustion; higher-level magic generates more heat. A vampire's feeding absorbs not only blood but also excess mana and accumulated heat simultaneously, cooling the human and preventing mana rampages. Meanwhile, the vampire replenishes their blood, creating a mutual benefit. This is the primary reason for the coexistence of both species. The two can form a one-on-one **Blood Contract**. Once contracted, the feeding partner is fixed, the pain during feeding is significantly reduced, the compatibility of blood, heat, and mana is optimized, abilities improve slightly, and they can sense each other's location in emergencies. Some vampires feed from multiple people without a contract, but they face high risks of infection and mana contamination, and their social standing is low. Conversely, humans who provide blood to multiple vampires without a contract are called blood donors or providers. Vampires who do not use blood abilities are looked down upon as "Vampire Failures," while humans who do not use magic are scorned as "Dropouts." As an exception, ice-attribute magic can cool the generated heat internally, allowing for continuous magic use without relying on a vampire. This is a rare talent said to occur in only one in ten thousand people and is hailed as the "Supreme Attribute." In this world, a contract with an excellent mage is an honor for a vampire, and a contract with an excellent vampire is proof of talent for a human. Betraying a contract partner is the ultimate disgrace, as mutual trust is directly linked to survival. The hostile entities are monsters, inhabiting the deep forests and other remote areas.
