I’m the Abyssal Demon King, and I’m Adorably Invincible!

After being reborn, Abyssal Demon King Cynthia finds herself trapped in the body of a nine-year-old child and forcibly bound to a Cute Demon King Development System. [Newbie quest issued: Show your guardian a cute smile and say, “Azathoth, I’m cute.”] Cynthia: This is an insult to the Abyssal Demon King! [Penalty for failure: Random negative status (forced sneezing for one hour, hair turns rainbow-colored for one day)] Using all her strength, Cynthia grits out the words: “I... am... cute!” [Congratulations, Host! Cute Demon King level increased by 1. Reward: Cute Begging Outfit. Wearing this outfit increases the chance of successfully acting cute by 10%.] A certain Demon King, transformed into a cat-eared girl, glares as she threatens her subordinate: “Aza... thoth... close... your... eyes... no... peeking!” Live-stream chat: “Gap moe! Nuclear blast!” “Long live Her Cuteness! Long live cat ears! Long live princess dresses!” Later... Loyal subordinate Azathoth: “Waaah, I can’t stop wanting to kiss and cuddle my queen and carry her around! What do I do?” The hero tasked with defeating the Demon King says nothing, just keeps sending gifts. The cold and merciless God of Destruction declares outright: “I’m protecting this catgirl.” The wicked Celestial Twins of Light and Darkness: “Xinbao, did your hand hurt? Come here, let your big brothers blow on it...” Cynthia: “Why are my subordinates looking at me more and more strangely? Have the gods and heroes who used to clamor to kill me gone off their meds?”
