Beneath the yellowish evening sky of the city of Chitose, an airplane passed calmly—until a bright flash appeared from inside its cabin. Strange symbols filled the walls, and panic spread within seconds. Something happened. And it was not an accident. At the same time, Riota and Keina two high school students, had just returned from school. In the middle of their journey, the sky rumbled violently. A great tragedy occurred that afternoon in the city of Chitose. However, all of this had been planned. By someone who possessed power beyond reason. He only wanted an answer. On the brink of death, Riota’s soul was thrown into a foreign realm and met a Goddess. A second life awaited him, something called reincarnation. Riota’s reincarnation at first was outside the line, triggering an uncorrected error, causing everything to not go as it should. (The synopsis is a bit too long, so I posted it in the notice chapter below, you can read it.)
