Summary
They are quintuplet brothers, all with identical faces. All of them are cross-dressers. The mysterious beauty "Omiru" living in a Kyoto mansion is the sister of the Ashimoto Kyōdai, and she, being a sister, has a ruthless personality, using her beauty to extort money from men. Unlike her brothers, the sister is beautiful but has a bad character.
As their name "Ashimoto (meaning they are adept at exploiting others' weaknesses)" suggests, they excel at unscrupulous business practices as dishonest merchants. They do not shy away from committing misdeeds for money, engaging in inhumane and malicious acts. These greedy, villainous brothers have no room for defense but, in a way, possess strong personalities as villains and hated characters.
