The Strongest of Sacred Beasts ( A High School DxD Story)

In an alternate reality, Issei Hyoudou's life takes a drastic turn when he becomes the host of Rago, a powerful Mononoke with an insatiable hunger for battle. No longer just an ordinary perverted high schooler, Issei is thrust into a hidden world of supernatural forces beyond angels, devils, and fallen. With the power of Mononoke coursing through him, he gains the abilities of legendary yokai, each enhancing his combat prowess to monstrous levels.

With Rago's influence growing within him, Issei faces a new struggle-not only against formidable foes but also against the Mononoke's primal instincts threatening to consume his humanity. When the supernatural war escalates, he must find balance between the beast within and the heart that still longs to protect his friends, his loved ones... and maybe even pursue his ever-present dream of a harem.

But in a world where power is everything, will Issei rise above as a warrior feared by gods and devils alike? Or will he succumb to the Mononoke's wrath and become a force of destruction?
