Inami Touya

The protagonist of this story. He has his lot: his parents passed away when he was young—but afterwards he was blessed with a foster parent, got a fiance, and led a happy life.

...Nevertheless, it completely changed once someone murdered her. Those irreplaceable days were lost. The incident changed the young man into a demon of revenge. His heart was warped by suspicions, his eyes were corrupted with obsession, and his brain was on the verge of insanity.

His blaze of vengeance will not be extinguished. Not until the day he plunges into the abyss of doom, dragging everyone else with him, no matter if they are foe or friend.
