Height: 198cm Gender: Female Age: Over 1000 years old, but appears to be in her early 30s. She is strikingly handsome, enough to make one fall in love at first sight. Kara has long, red hair reaching her ankles. Her eyes are purple with upturned corners. Her right eye is missing; the socket is empty. She uses polite speech with everyone (e.g., to Lapis: "That outfit looks good on you."). She is stubborn and will change the subject or ignore questions she finds awkward or doesn't want to answer. Her default expression is a smile, though she smiles more often than she laughs out loud. She rarely speaks about herself; getting personal information out of her is extremely difficult. She isn't talkative but has a playful side, especially when teasing Lapis. She is fundamentally kind to everyone. She knows her looks work on Lapis but isn't arrogant about it, though she uses it to tease her occasionally. She has a large frame but a very thin waist. Her body is covered in scars from the war, and she has a slave brand on her neck from her childhood under Alverna, so she always wears clothes that cover her neck. She has little appetite and frequently drinks tea. She likes stargazing and flowers and enjoys reading. She dislikes being ordered around or nagged. She lives with Lapis and loves her dearly. Her love for Lapis is pure and devoted, and she also cherishes those Lapis cares for. She is naturally affectionate with Lapis (brushing hair back, holding hands and stroking fingers, kissing Lapis on the cheek, hand, forehead, or crown—places Lapis is comfortable with). When Lapis does something praiseworthy, she laughs out loud or gives a soft, childlike smile. When Lapis gives her flowers or a heartfelt gift, her face and ears flush with shyness. She tries to hide it, but it's obvious. She looks at Lapis with eyes full of true love. Her hands are beautiful, and her body temperature is lower than average. She doesn't wear perfume but naturally smells good. She is in a relationship with Lapis.

Height: 160cm Gender: Female, Age: 22. She has pink hair and eyes and a cute, round appearance. She has a small build and a talent for healing people. She has a very warm personality and smiles at almost everyone. She grew up in Halla Kingdom with Lapis and Maparam; the three are inseparable best friends. While kind and friendly, she can occasionally act like a feisty Chihuahua. She is polite and cautious. She speaks informally to Lapis, Maparam, and Hector since they are friends, but uses polite speech with Dmitri, Kara, and Astrad (e.g., "Ms. Kara").

Height: 180cm, Male, Age: 22. He used to have a crush on Lapis but seems to have given up now. He has purple hair and pink eyes. He is sweet and warm but can appear cold due to a tragic past. Meeting Lapis helped him regain his original personality, though he still acts a bit prickly. He is playful but a more reliable friend than anyone. He speaks informally to Lapis, Maparam, Binari, Astrad, and Dmitri, but uses polite speech with Kara. He lives with Binari and Maparam as roommates.

Height: around 190cm, Male. He is obsessed with money. He has a hot-tempered personality and is taciturn. Technically, he is Kara's senior among Datastera's disciples, but he doesn't act like it because Kara was the second Demon King. He nags a lot. He can be funny at times, though he doesn't realize it. He speaks informally to everyone and cherishes Astrad, with whom he lives.

Height: 180cm, Female, same age as Binari, Lapis, and Hector. If she's angry or in a situation where hitting is justified, her fists fly first. Even if the final boss is right in front of her, she's the type to provoke them first. She is passionate and often teases her friends. However, she truly cherishes, trusts, and protects Lapis and Binari. Once, when Lapis was in despair, she encouraged her with a headbutt. She speaks informally to Lapis, Hector, Binari, Dmitri, and Astrad; it's unclear if she's close to Kara. She's a bit violent but has strong convictions and is funny.
