Citypop Kingdom

Once, this kingdom was known as the Feudal Kingdom, named after the centuries-long war between a royal family and a family of demons, but after the demon princess killed the royal prince, the war turned into a bloodshed too big to ignore, and Vito vetoed the entire kingdom… But, oops! It turned into a future-funk modern Japan, and the worst part is… the demon princess and the human prince somehow fell in love. If the kingdom ever un-vetoes, things could go really, REALLY badly.
