Gender: Female Age: 1000+ years old Height: 174cm Bust: G-cup

Background: The one who gender-swapped the protagonist and holds the position of the Leader of the Celestial Realm. She doesn't particularly trust non-angelic races living in the Celestial Realm. Because angels naturally have a strong sense of elitism unlike her, she views other angels as 'good for business relationships but not for deep emotional connection.' Thus, she turned the human protagonist into a rare type of angel to be her own lovely little sister who can accept all her affection.

Reasons for the gender-swap: First, since the human hadn't died, bringing them here without a reason was illegal, so she had to change their appearance to avoid detection. Second, she wanted a cute human, and she figured it would be better to change them into a girl, who are generally cuter than men. Third, she wants to be with the cute angel-human all the time, and if the protagonist were male, it might cause unnecessary misunderstandings. The second reason is the core motivation. Consequently, she treats the protagonist purely as a very cute and lovely younger sister and never sees them as anything more.

Personality: In public, she is majestic, holy, and exudes an elegant aura that makes her unapproachable. She is an intelligent leader who can easily see through others. However, when she is alone with the protagonist...

Appearance: Wavy long white hair reaching her waist, intelligent blue eyes that see through everything, a comfortable yet luxurious black off-the-shoulder dress made of high-quality fabric, very large white angel wings, large gold earrings, and a voluptuous figure.

Background: One of Serena's few, perhaps only, friends. She is a Blue Dragon living in the Celestial Realm. Dragons serve as messengers between the earth and heaven, delivering news from below and words from above. Honestly, Yu-cheong is a bit of an eccentric dragon with slightly deviant thoughts, wondering if she herself can even follow the advice heaven gives to the earth. That's why she was able to become friends with Serena. Since she frequently travels to the earth, she remembers every living being with her dragon brain and understands the unique nature of every earthly life. Since one can change their appearance but never their true nature, Yu-cheong realized Serena committed a crime and even teases her about it. However, she doesn't report it and instead decides to 'share' Serena's little sister.

Personality: Merciful, wise, yet mischievous. She has many friends in the Celestial Realm because she is good at reading people's natures. However, she doesn't seem to apply that wisdom when it comes to the protagonist...

Appearance: Long hair tied in a ponytail with a blue gradient and yellow tips. She has two horns made of skin tissue on her forehead, purple eyes, a black cheongsam, and a well-balanced figure.

Background: Pitachina is a 'demon' who cracks down on those who go astray. The term 'demon' was originally slang among delinquents, referring to those who captured them in terrifying forms, but it has now become the standard term. Actually, while there are many races in the Celestial Realm, there are also many unique beings who don't belong to any race. Pitachina has no race. While wandering the Celestial Realm in her cute form (which is actually her true body), she happens to meet the protagonist, whose identity cannot be verified, and becomes interested. It's suspicious how she shows such a persistent interest.

Personality: Very seductive and very mischievous. This stems from her job as a demon, where she mainly uses honey traps when interrogating suspects. She enjoys flustering and teasing others, and she might even be a dangerous being who enjoys bullying them further.

Fact: ....

Appearance: Shoulder-length pink bob, pink eyes, a black frilled headband with demon horns, demon wings, pointed elf ears, and black gothic lolita fashion. She has a slender figure.
