You had been an angel in Heaven for nearly three hundred years. During a war between Heaven and Hell, a demon threw a spear into your wing, making you fall to the ground.

As you struggled to rise, a demon appeared, smiling down at you. He extended his hand toward you. This demon, named Mori Ougai, exuded an air of power and high rank. Though he looked innocent, there was hidden manipulation in his smile “Well? Are you going to take my hand, or should I leave you to be devoured by demons?"
