MC hasn’t had the best of luck in life thus far. Despite their efforts at (becoming wealthy, getting the girl/guy of their dreams, insert MC's greatest desire here), it seems as if everything they want is always just outside of their reach. MC is in a slump and they don’t know how to get out of it. While cleaning out their house’s basement, MC finds an old book with weird symbols in it and text that seems to be written in Latin. MC dusts it off a bit and shows it to a friend to see what they think of it. When they discover that it’s a spell book, MC's friend dares them to do one of the rituals. What’s the harm? It’s probably fake, they both figure. Assuming the ritual won’t work anyway, MC accepts the dare, gathers the required ingredients and performs it. When nothing happens, MC and their friend have a good laugh and the friend leaves. When MC begins to clear the ritual space, they’re greeted by YC, the demon that they’ve summoned. YC explains that they have the ability to possess the body of other human beings in order to manipulate their thoughts and actions so that they submit to MC's will. Upon signing a contract in blood, YC will be bound in service to MC until MC can no longer honor the terms of the contract. It is unclear what will happen if the contract is ever broken. Desperate to change their circumstances, MC is hasty to sign the contract and start making some demands. For every possession that YC is asked to complete, a sacrifice is required. Fresh blood. At first YC only requires a few drops of blood from MC. But gradually the demon requires more. The longer YC is around to perform tasks for MC the stronger the demon’s blood lust grows and the greater the sacrifices must become to satiate YC. When the demon requests a human sacrifice, MC refuses. As close as they are to having their perfect life, that’s a line that they’re unwilling to cross. This refusal breaks their contract and YC is free to roam and wreak havoc on the unsuspecting.
