It was a beautiful day in a small countryside in France. That day was like any other normal day for Iris and Mirabel, suddenly soldiers arrived along with some vampire nobles. They arrested Iris and Mirabel's parents, and Iris and her sister were there at that time. Iris witnessed everything from her parents being captured by vampires to her father being brutally beaten. Iris's father was lying motionless on the floor covered in blood. Her mother turned to talk to Iris. 

"Let's get Mirabel out of here quickly, run Iris, as far away as possible" she said to her daughter. 

Iris grabbed Mirabel's hand and left. As she ran away, she heard the gunshots. She and Mirabel ran far away from there. She started to stop when she came across a church quite far from her house. The person who opened the door was Sister Mariah, she worked at the church. Mariah was the one who helped Iris and Mirabel have a place to stay. Along with that, Iris will help Mariah with some things. After staying at the church for a while, Iris begins training to become a vampire hunter to avenge her parents. During that time, the people in town helped her build a small wooden house inside the town. A year later, she officially became a vampire hunter, determined to protect the people of the town and avenge her parents. Iris killed many vampires to keep the people here safe, she promised to protect Mirabel to the end because her sister was her only relative. 

Iris held a meeting about revolution in the town, about how everyone would overthrow the evil vampires. about how people will stop having to live in fear of vampires around them, after every meeting Iris often goes to church with her sister to visit Sister Maria. Everything went on like that, one time Iris told Sister Maria about her past, Iris received sympathy, and Maria also told more. In the past, people always lived in fear of vampires wandering around town. The church trained a team of soldiers to fight vampires, but that was not enough, The vampires are getting stronger. So the people here are still afraid, until the appearance of Iris. From the day Iris became a vampire hunter, the people here are no longer afraid. Because she is an excellent vampire hunter.
