This is a fanfiction... When Sesa woke up, he found himself in a new world. To be precise, it was the inner realm of what he thought to be a sacred gear. Boy, was he surprised to hear the words 'sacred gear', 'cause you know what that means! When Sesa left his gears world and entered the actual one, that's when his journey began, crossing over 'DxD' and find a way back from where he came... and create a harem along the way, beginning with her!!! Me: I am using this fan fiction to practice my writing. However, the story of the Mc might be just to your liking.
