Summoning Is One Thing, but What the Heck Is a Succubus Army?

Also known as: Full-Time Awakening: I Turned into a Succubus from the Start? Chu Sheng awakened the hidden class [Summoner]. He thought he'd be able to summon dragons and divine beasts and dominate the supernatural world, but his talent took a bizarre turn... His contract medium had to be pantyhose, and any living being who signed a contract would irreversibly transform into his personal succubus! Nylon stockings summoned an F-rank, dimwitted laborer succubus, while icy silkworm silk gave birth to an SSS-rank Succubus Queen. The head instructor came to purify me, only to transform on the spot into a bespectacled girl who loved to lecture. The enemy nation's Valkyrie, who had sworn to destroy me, became my clingiest personal guard. The hero party that came to defeat me, the undead calamity that invaded, and the lofty gods all ended up as members of my harem army. My chubby roommate willingly made a contract to save me, transforming from a two-hundred-jin hulk into a super-strong, muscular Barbie. Even the emperor of an empire who wanted to rule the world was tamed by me and turned into a tsundere big-sister-style housekeeper. The world calls me the most evil Demon King in existence, but only Chu Sheng knows the truth: I really just want to laze around and wait to die. It's these succubi who keep forcing me to unite the continent and save the world!
