Forbidden love

Kaminari Denki was a unique boy, a boy whom had met a suspicious figure which soon followed him each day to and from school every night when he was just seven years old until the age of 15. Nevertheless, he lived a relatively normal life among other humans just like him, soon after his 15th birthday the figure wasn't seen again until he turned 17.
This figure was a muscular and tanned Demon, Hitoshi Shinso, that spun his world upside down.

However, Hitoshi proved to be a rather cocky and rude demon whom thought he owned the blonde.
and seemed to have an unhealthy obsession with biting as if to prove his dominance as the owner of this boy.

Kaminari soon after teaching the demon manors and respect learnt that Hitoshi had taken an oath never to be with with a human being, disobedience of this rule leading in death.

When Kaminaris family was murdered in a car crash; left all alone he moves in with the demon boy when the blonde realises he has fallen for Hitoshi.

One night, while Kaminari is on a walk a person appears before him and warns him of magic that lies within him. The figure then gives Kaminari the only weapon that can possibly defeat those whom create a wedge between the boy and his beloved demon.

Will Kaminari find it in himself to awaken his power to finally be with the only creature who has ever made him feel truly loved?
