I Am a Part-Time Exterminator and Work as a Detective at Hogwarts [HP]

Brenda Reeve: "My mission is to find the murderer of the Reeve family. It is to protect the dark side of the world even at the expense of myself. I should sacrifice my life for this..." In 1986, the Reeve family faced a sudden disaster. The entire family was almost slaughtered overnight, except for six-year-old Brenda and her cousin Margaret of the same age who escaped. They had no choice but to take on the responsibilities of the family and stumbled around until they were eleven years old, when they received two admission letters from Hogwarts. She yearned for the life in a magic academy, but she couldn't let go of the responsibilities on her shoulders, so she had to live a life of attending classes during the day, running around at night, and occasionally having to miss classes.
