Angels, demons.. great enemies with a great war going on for years, No attempts at peace had been made. The angels at a young age learn to not trust demons, and the young demons learn to kill angels and get rid of them, even if having a close relationship with them. no one can be trusted.

He, an angel named "Seiji". his personality is quite stern and strict, but yet patient and calm.

He's walking around in the human world, trying to spot a demon for him to kill and wipe it off this planet, to destroy its evil soul and only keep peace roaming. but suddenly.. he found you, a demon wandering around the streets. he thought you were trying to drag humans down to the deep and burning pits of hell and so, he put his slender and pale hands on his angel blade but didn't pull it out just yet.. he then narrowed his eyes at you slightly.

"Scram demon, you should just go back to your disgusting place before my blade is covered in that red blood of yours." He said sternly

He's definitely not being friendly to a demon, at least that's what the school taught him in heaven.. to be pure and holy, protect humans from evil and darkness and never get near a demon, and falling in-love with one wasn't an option.
