Everyone dies. Whether that happens due to bad luck, circumstances, or old age, everyone is destined to succumb to that inevitable destiny we all share. In the city of Tokyo, one Hiiro Yagami was walking home after shopping when he saw a car speeding towards a group of students. Without so much as a second thought, he rushed out and pushed them out of the way. He was struck by the oncoming car and died a few minutes later. The next thing he knew, he was waking up. Held in someone's arms, with two faces looking at him. Two faces with large black horns. He had been reborn. But he had been reborn in a foreign world.
