Nakanaide Maou-chan

Synopsis

Demon Lord Astarolin, even though her power and attitude can be considered of a demon king, her cute appearance and lack of a strong presence made the heroes view her as a cute and tiny animal. That her subjects are doting on her too much doesn't help in the slightest... Follow the adventures of this tiny and cute Demon Lord in her quest to become a being befitting her title in power and appearance. (Source: MangaDex)
