Takeru and Kina are two children living in the shadows of our dimension and fighting demons who seek an evil goal. Takeru is of human dissent but Kina's mother is a demon, they must fight the evil to their last breath and protect the secrets of the night. But with evil getting more active can they stop the truth from being revealed. Not sure were this is going so T too be safe.

This is a digimon-winterling crossover but I couldn't find a winterling category so I did what I could.
