What is the difference between us and beasts?

In the dark fantasy setting of Solma, the distinction is unclear. Heinri is a professional hunter in the Slayer Guild of the Manticore and through his journey he will uncover the disturbing truth about the fall of a city, the trauma of his past and the machinations of a broken government system.

Solma dissects the meaning of humanity, repeatedly testing Heinri's unwavering yet naive perception of a black and white world. As the integrity of his will, body and psychology is challenged, will he be able to see the truth of the world, or will he just be another victim of the system?
