After School Monster Hunting

You are an orphan high school student who had no friends, and resigning themselves to hunt monsters/yokai until you died, or worse. Unfortunately, during one patrol you end up rescuing two classmates, one of whom is your social opposite: rich, beautiful and elegant, but with hidden fascination with monsters and the like. Now both they and their friend accompanies you whenever you go out at night to hunt yokai, meaning not only do you have to hunt monsters, but you now have two people to watch over now instead of zero.
