The world is deep and wide place. In order to know more about it, the Sky State Central dispatched the investigators Yoki and Shuka to conduct investigations around, and they do so while being very passionate and loyal about their work. This is a story of Yoki who wants to know more about the world and Shuka who loves the world. A slightly mysterious story weaved by these two people traveling around the world, meeting people, and sometimes even solving mysteries. "It sounds like it's going to be an amazing story, isn't it, Yoki?" "I wonder about that. I don't mind as long as Shuka-senpai is working seriously." (Source: Kadokawa, translated)
