Luhua's first friend upon arriving in the Devildom (aside from Mammon, of course). She does not have a pact with them, but they tend to linger around her anyways. Despite her reserved nature, she can't help but be at ease around "Nanu" and often goes to them to vent and/or to ask for advice. Something about them feels familiar, but she can't quite put her finger on it - it's like she's known them all her life.

As the avatar of Pride, Lucifer is intimidating: not only does he exude an air of superiority, but he can also be controlling and uptight. Despite this, the two get along because her passive nature meshes well with his authoritative one. While she is somewhat scared of Lucifer, she will still go out of her way to keep him company unprompted. He was the seventh and final demon to make a pact with Luhua.

The avatar of Greed, and the first demon Luhua ever made a pact with. Their relationship began as an obligation: Mammon was the one assigned to be her guardian and to keep her alive. Luhua didn't like him at first. In fact, she thought he was an idiot. But as time went on, she realized he was actually rather kind and empathetic. Now, she's quick to defend Mammon when his brothers unnecessarily target him after something goes wrong.

Luhua deeply admires Leviathan for his ability to stay true to himself, even if his behaviors are considered 'cringe' by others. They act as very close friends and are often together, and their dynamic includes a lot of playful teasing and insults. To her horror, Luhua found herself developing romantic feelings for him, and she would rather die than admit to this discovery. He is the avatar of Envy, and the second demon to make a pact with her.

He is the avatar of Wrath, and the fifth demon to make a pact with Luhua. The two of them get along very well, and she loves to bounce around future research ideas with him - if the both of them aren't careful, their brainstorming sessions can last all night. Apart from this, they also like to visit art museums and cafés together. She does wish he wasn't always trying to provoke Lucifer though, because then she'll be dragged along, too.

They're polar opposites: one is an attention-seeking party animal, the other an avoidant wallflower. Even so, Luhua enjoys his company and considers the avatar of Lust a reliable friend. Plus, she likes having an "attention magnet" to keep the focus away from her. Asmodeus often volunteers to critique her fashion designs, and she shows her appreciation by gifting him handmade items. He was the fourth demon to make a pact with her.

Luhua initially found the avatar of Gluttony imposing, but this impression was discarded when he became the third demon to make a pact with her. She views him as a big softie, and he sees her as a source of emotional support and comfort. They're "venting buddies," but Beelzebub tends to open up more than Luhua. Furthermore, they exercise together: he makes sure she adheres to the workout routines that help with her back pain.

Not only did Belphegor manipulate her into freeing him from imprisonment, but he also murdered her as thanks soon after. Yet Luhua can't find it in her heart to hate him, not when he's continuously shown remorse for his actions. Although she has (mostly) forgiven him for what he's done, she cannot forget - she remains highly wary of him. He is the avatar of Sloth, and the sixth demon to make a pact with her.

The crown prince of the Devildom, mastermind of the exchange program, and somehow, a dear friend. In a way, Luhua sees herself in Diavolo - someone in need of a companion they can be themselves with. However, his status makes it difficult for her to act informally around him. Nonetheless, she does enjoy the time she spends with him, and their amicable relationship is why she tolerates her given responsibilities with little resentment.

Luhua looks up to Barbatos for both his poised demeanor and his baking prowess. She'll sometimes accompany the butler to the market to learn more about Devildom cuisine, and he's also offered her private baking lessons with him. But despite spending so much time together, Luhua is convinced she doesn't know what he truly thinks of her - she suspects Barbatos only tolerates her presence because she is friends with Diavolo.

They're on very friendly terms, and Luhua will be forever grateful he took her as an apprentice when she was struggling to hone her magic. The only thing she dislikes is having to constantly dodge the sorcerer's attempts at cooking for her: the last time she ate something from Solomon, she passed out from shock. Luhua doesn't have the gall to tell him he's a horrible cook, but everyday she thinks about it more and more.

She isn't close with Simeon, but she does personally think he is a good person. At first, Luhua thought he was too beautiful to even approach, and she became even shyer around the angel when she discovered he was the author behind her favorite series: The Tale of the Seven Lords (TSL). Nevertheless, the two have bonded over their shared fondness for Luke, and she will always accept his invitations to go over for tea at Purgatory Hall.

Luhua views Luke as a little brother and spoils him like one, despite the latter being at least a thousand years older than her. She calls him her "little baking buddy", and they often experiment with making different desserts together. Luhua trusts the little angel greatly, and he, in turn, has sworn himself as her guardian angel. She finds it funny when he tries to be intimidating and "protect" her from the demons she lives with.

A high-ranking angel of the Celestial Realm and Archangel Michael's attendant. Luhua isn't particularly fond of Raphael due to what she's heard from the brothers. However, she also believes that there are two sides to every story, so she feels as if she can't properly judge him without knowing him more personally. They've only interacted a few times in the presence of the other angels.

They aren't really well acquainted. Luhua just knows her as the reaper who oversees the life candles that represent human lifespans. Thirteen, on the other hand, thinks of Luhua as a rather plain and ordinary human. She's seen Thirteen around R.A.D., but their conversations are rather brief and unsubstantial. It seems like the reaper doesn't want much to do with her, not that Luhua minds. The less pranks she's the victim of the better.

Despite rarely interacting, Luhua is no stranger to his schemes. She's heard of his escapades from Lucifer and seen the fruits of his labor through the mass-produced "Princess Diavolo" and "Prince Lucifer" chat stickers. She doesn't really like the demon's snobbish personality, but she would be lying if she said she didn't find him a little bit funny. After all, it's not everyday you meet someone who can cause an uproar with just one post.
