Unmanned Observation Bureau

Ghosts, elves, vampires and even aliens. In fact, they all exist, and they are even said to be living around us. Maybe the owner of a certain breakfast shop is a visitor from Mars, or maybe a famous model is a thousand-year-old fox demon. The Loch Ness Monster just wants to come out for some air, and the crop circles are just a joke of the elves. And the reason why we know nothing about this is because there is a mysterious organization secretly maintaining the relationship between us and non-human beings. This organization is called the Non-Human Observation Bureau.
