Ragur, a Royal Knight from another world has passed away after defending his country against the demons. After waking up he found himself in a place where everything is white.

There was a woman floating in the air who called herself a goddess. She promised Ragur that she'll reincarnate him to a place called Earth if he swears his loyalty to her.

After the goddess reincarnated him to Earth, he woke up as a baby laying under a bridge. He stayed in the cold and starved there for hours till a girl came and took him to the orphanage she was raised in.

When Ragur waked up again he found himself on a bed, with a girl laying next to the bed.
