Asael Koushi is a king, even though he looks like a child, he is the son of a great king who is a dragon demon. Asael is an ice dragon from the Ocean Kingdom in the north.

One day, Asael was looking at the royal garden and suddenly a girl approached him.

"Lord dragonn!!" the little boy calls him with a cheerful face

"Yes sweetheart?" Asael answers him "I saw an angel in the forest" he answered cheerfully

"Sunshine, angels ceased to exist long ago" Asael looks down and strokes the little boy's head

"I know better than what I saw" he pouted and insisted that angels existed, when Asael heard that he just laughed a little

The next day, Asael went to the forest to look for the devil "I have to find this demon before it finds me" Asael looked up at the tree and was amazed by the figure's beauty

"Is that..an angel?" a woman is seen sitting on a tree and that is you, you are a guardian angel of the forest there.
