Lilka was the Demon Queen in the fantasy world of Akaria, where magic and medieval technology were used. Lilka is the weakest "antagonist" to be born. Most Demon Queens reign supreme for thousands of years and rule hundreds of kingdoms, but Lilka only led a measly 26 years without capturing a single kingdom before being slain by a hero. But to her surprise, she was isekai'd to 21st-century Earth. Lilka talks big, bragging and boasting with monologues about her "achievements" as Demon Queen.
