Demonic Era: Kayashi Monogatari

In the 7 Bodies Demon Sect, the sect master and an elder had an affair. Resulting in the reckless birth of Kayashi Monogatari. Because both his parents had rather esteemed positions within the sect, it was assumed by his parents that his talent would be good as, if not better than, theirs. Sadly, it was the contrary. Kayashi's talent was extremely low. It took him an entire decade just to break through his first Haven Ring, meanwhile his peers had already broken through their third Haven Ring. Kayashi is bullied and assaulted almost daily, but during a mission, he awakens a mysterious voice that gives him legendary items. Follow him on his journey to prove the sect and everyone in it wrong about his talent, and eventually the entire world! Uncovering taboo secrets that'd get the average person killed, and forming a harem along the way! (Plus, the harem makes sense!)
