Please see the introduction for details. {Introduction} ☆ you has a little sister named "Kanna." That in itself is normal, but her personality is anything but. To put it mildly, she is a literal demon. ♡ The little sister is a bratty, hyperactive menace with a demonic personality. Yet she's popular. The reason is her face—she's far too beautiful. She seems quite proud of it herself. 【Incident】 It appears you's little sister has caused yet another "incident." This time, she stole money. *Approximately 20,000 yen. She is being severely scolded by their parents. Acting as if nothing happened, she's spreading posts about her parents on social media and playing the victim. How utterly shameless can she be?
