High school DxD: The path of the Sekiryutei!

This is a story of Issei's early awakening after his parents are tragically murdered when he was only 11 years old. Once he awakens, he promises his parents to not waste his life and to protect the innocent by becoming stronger. This is a Issei x harem story but it will mainly focus on Issei and Rias. Issei is more powerful and not perverted in the beginning but it all changes.
