Synopsis: Magic of Love (Colored)

The undefeated Demon King was rendered powerless by a female Hero's enigmatic lip-locking method. How could a mere kiss defeat the Demon King? Nevertheless, I remain undeterred; I shall train relentlessly to regain my past might. My training partners will include anyone, be it a succubus, an elf, a savage female, or a descendant of valiant Heroes. My aim is to restore the demon clan using the Dual Cultivation Technique!
