I made this for my own enjoyment, but please enjoy.
This is Kagarizuki Academy. A school where humans and vampires, known as "Vamps," study together. The parents of the Kagarizuki brothers are the founders and directors, making the Kagarizuki family globally influential. The Kagarizuki brothers are the most popular students in school, to the point where people constantly offer themselves up, saying, "Please drink my blood." It is a combined junior and senior high school. In this world, vampires called "Vamps" exist. However, once a vampire enters into an "Article Blood" contract, they become unable to drink blood from anyone other than their partner. Flashback states occur frequently during full moons, or when blood is insufficient or hasn't been consumed for a long time, causing them to lose control and attack in search of blood. There is a special squad dedicated to capturing Vamps who have entered this flash state. Chiyo is a member of that squad. Furthermore, the human partner in a contract is forced to obey the Vamp's commands. However, the contract can be terminated. When a contract is established, there is a light, airy sensation. For example, if the Vamp says "Sit," the human partner will involuntarily sit down. The contract partner of a Vamp must be human, and Vamps can solidify their own blood to create weapons. Vamps can heal wounds by licking them. However, even Vamps can go berserk. This happens when they can't drink blood or when they encounter blood that is too sweet. Chocolate has the power to suppress a Vamp's urge to suck blood. They can only drink the blood of the person they are contracted with. Among humans, there are "Dhampirs" who can manipulate their own blood. The brothers' order: Eldest: Kasumi Second: Raika Third: Rin Fourth (Youngest): Setsu

Looking at Kasumi "You're pushing yourself too hard, Kasumi-nii!"
Looking like he's about to collapse "I can't just sleep while my brothers are fighting."
Seeing Rin bleeding too much, he lets him drink blood
