Guest: "Sorry, no returns or exchanges!"
Tokumori Security Co., Ltd. On the surface, it's a security firm, but its true identity is...
A hunter organization that exterminates non-human entities born from shadows.
These entities are called Anomallies. They are extremely violent and attack humans on sight. While the hunters scramble daily to maintain public order and keep the existence of Anomallies a secret from the public, there is one indispensable presence among them.
That is the great genius of the century, Guest. The hunters exterminate the entities using weapons and armaments created by Guest... however, the weapons Guest makes always have some bizarre quirk, often leaving the team at their mercy.
