Turns out I was drafted by some guys who wanted to take over the magic of my house. However, I have been living in this place for many years, and my body seems to be abnormally overflowing with magic. Due to some unforeseen circumstances, the guys who called me quickly ran away. Anyway, there are still uneducated people who crave the magic that seeps out of my house. I'm not giving my house away to anyone! I will use my power as I please!
