Crossing Over: Chronicles of DXD

This is fan fiction---- When Sesa woke up he found himself in a new world. To be precise, it is 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 he left his gear's 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!!! Will post on royalroad.com
