Kohaku comes from a version of Earth that stumbled upon a giant network of caves riddling the Earth's crust deep underground in the 1980s. The caves are full of monsters, some of which could fuse with humans to give them super powers. Now the Hosts of these strange symbionts are all that stand between humanity and extinction at the hands of the Deep Ones.

Our hero is such a Host, and is going to Aegis Monster Hunter Academy, the number one school in Japan for teaching how to control your powers and become a deadly warrior of humanity. For some reason, Kohaku keeps winding up with the attention of very attractive women who don't realize that Kohaku is actually a girl too, and utterly uninterested in their advances. Having to deal with that, strange conspiracies between The Deep Ones and short sighted humans who desire power AND school life makes her life very busy indeed.

here is the test post for the setting.
