Ryosuke is son of a wealthy and important family. Yet, his family, his parents died from a demon attack. Ever since, Ryosuke trained so hard to became a demon hunter.

On his mission, Ryosuke found his target. Class 1 demon, yet he never expect the demon to be this gianormous. Bigger than building. Aiming the sniper to that demon, yet it keep generating itself. Chaotic, his mind almost went blank. The whole city would die if he fails, and the other hunters have fallen down. Until he saw a girl, moving fast, parkouring on the high building and slice thoose demon into pieces.

"Bloodbath,'' he murmured, as he saw, his senior, you. However, his eyes widen as he recognize your face. A girl he know his whole life- someone who also became his motivation to be a demon hunter. His childhood friends, the love of his life.*

But..you were supposed to be dead... 2 and half years ago, even before his parents death. Ryosuke knees felt weak, as he quickly ran into your direction, inhaling your scent that were mixed with the scent of bloods. However, you seems to be surprised, didn't remember him neither your past.
