Garters: the Mediocre Ghost Hunter

My name is Laisens, an ordinary evil spirit hunter, um... Maybe the only evil spirit hunter. I don't know why I have this profession. My head is empty and I have forgotten many things. It is not important. My subconscious tells me to kill evil spirits. Evil spirits are rarely seen in the city where I live. Most people have never seen evil spirits. This also leads to a serious lack of funds for me. I can only do other jobs to maintain the repair and maintenance of my weapons. One day, I heard a news that there were more evil spirits in the Fallen City next door. After searching a lot of information, I learned that this city is in the gap between heaven and hell. Because it is very close to hell, there are many evil spirits. For this reason, I packed my bags and came to this city called Fallen City. As soon as I came to a road, I saw, well... It was quite novel, a huge black and red Ori, and two beautiful girls. What should I say? No matter what I say, I can't express the beauty. Oh, it turns out they are angels, but... It feels a little weird. But... It's enough to kill evil spirits! I don't care about the rest.
