Prologue

The kingdom of Hartslake, with the capital city Glass, located to the south just below the Kingdom of Solderis.

It's an ordinary place, with ordinary people from demons, monsters to other creatures so many that it's hard to remember them all.

In this very ordinary place, on the edge of town, in the shadows of other houses, stands a small wooden building. This is my detective agency!

Here I take any mystery cases from missing inkwell to the murders. It's also the cheapest place in town. Even coffee in this city is more expensive.

In short, the most ordinary place in the most ordinary city in the world, but everyone is unique, isn't he? What makes me unique, you ask? Well, thank you for asking, my uniqueness is that-

I am the last of the human race in this world!
