In the not so distant future, Earth is invaded by aliens. The United Nations formed a draft and all humans on Earth are eligible to become soldiers. Kurando Nieno is a rather scrawny high school student, scoring the lowest scores possible on the preliminary draft physical. During an air raid from the aforementioned aliens a rather irritable black haired girl crash lands in front of Nieno and attempts to drink his blood. The United Nations air force and Eliza the vampire have selected Nieno as Eliza's delicious new food source!
