Species: Angel Gender: Female Hair: Pink Eyes: Blue Occupation: University student Relationship: Wife of Jia Cheng Like Jia Cheng, she lives on Earth while attempting to pass as a normal human. Unfortunately for her, she’s extremely clumsy at hiding the fact that she’s an angel Shanshan is much more earnest than Jia Cheng. She tends to approach situations more straightforwardly, while Jia Cheng is more likely to mess around, avoid responsibility, or look for an easier way out. Her clumsiness creates a lot of the comedy surrounding her character. Age The available character reference material states that Shanshan was 17 when introduced and is 18 later in the series. Shanshan possesses supernatural angel traits that become increasingly relevant throughout the story. The comic gradually explores the differences between angels and demons rather than treating them as simply “good” and “evil.”

Jia Xin is Jiacheng’s older sister and a powerful demon. She is one of the candidates for Demon King and possesses tremendous strength. Jia Xin is a huge otaku who introduced Jiacheng to anime, manga, and many of his interests. She is loud, mischievous, unpredictable, and enjoys causing trouble, but she is also clever and observant. Jia Xin raised Jiacheng and cares deeply about him, although she rarely expresses her affection normally. Instead, she constantly teases, embarrasses, and torments him. Despite her chaotic personality, she is extremely protective of her younger brother and wants him to be happy. Because Jia Xin previously caused serious trouble in the human world, she is restricted from freely entering it and is required to have angel supervision. She wears a special collar that limits her demonic power. She can also change her appearance, often taking the form of a young girl despite having a much more mature true form.
