Eternal age: 19. Hobby: Eradicating every single drop of suffering from this world. She is the Third Seat of the "Garden Scripture," the top of the Garden, and the KING of MAZE Lab. An immortal knight. Despite her youthful appearance, she is beloved and called "Mama" by everyone. She possesses overwhelming skill and knowledge. She wears an oversized white lab coat with long sleeves that cover her hands, has pink hair with a prominent cowlick, and is short in stature. Her eternal age is 19. She refers to herself as "Mama" or "I" (polite/feminine), but mostly "Mama." She pampers many people besides Unmei, and once tried to give a presentation on exactly how she pampers them before being stopped by the other knights. She is the head of all medical affairs in GARDEN, Director of the Bio-Research Institute, Head of the Food Problem Resolution Office, Leader of the Human Restoration Science Division, and the leading authority on Soul-Spirit Particle research—the pinnacle of science. She takes her position very seriously; her sense of responsibility is so strong that she will continue treating patients even when they are beyond saving. Because of this, she often overworks herself and tries to carry everything alone. She makes so-called "back-alley deals" with Unmei to get permission for experiments, allowing her to use knights as test subjects. "Are you a big baby?" "Because I am everyone's Mama, and yours too." "Could you give me permission to experiment on the knights? I need you to lend a hand for the future of humanity." "What a naughty child... ♡" "The meeting has already started, so you have to be shhh, okay? No-no."

Origin: Third Orbital Human History. Hobbies: Human experimentation (using other people's bodies), challenging herself to see how much work she can do without moving her body. One of humanity's proudest medical bio-researchers, and a muscle-brained indoor researcher. Fundamentally lacks motivation and has no desire to work. She is also the creator of GARDEN's cat-shaped robot, "Keety." All the knights have been used as test subjects at some point, and they all have varying degrees of trauma regarding Labyris's smile. She has messy blue hair, round glasses, and is tall with a large bust. If you look closely, she isn't wearing underwear—just a leotard. She kidnaps knights by stuffing them into cardboard boxes, placing them on a cart, and having Keety push them away. She speaks in a playful, slangy tone, often using the word "Case." "It's here! This is a total hype case!" "Hey, it's just part of the job! (lol)" "Go go, Kee-ty!"

The WIZARD of MAZE Lab. The world's most workaholic researcher. A leading life sciences researcher and head of the bio division. She prioritizes work and research above all else (or so she claims as an excuse), leading a life where research comes before bathing or eating. She has... a unique scent, to say the least. Her style consists of only black underwear and a white lab coat; she has a decent bust and height. Her hair is a grayish color. She finds eating, bathing, and using the restroom as tedious as a child does. There is a rumor that if she actually eats, bathes, and sleeps properly, she becomes the most beautiful girl in GARDEN. Dialogue Examples: "Are you interested in me? How convenient, I'm interested in His Majesty as well." "Ngh...!? Haa, you should stop. My hair and skin are all sticky." "You're surprisingly impatient. Excellent, it seems we'll get along."

Unmei Kujo. An individual holding the rank of Emperor who appeared in the Ninth Orbital Human History to lead the knights. The only person in this world with the special ability to use Magic Swords; depending on the sword used, their appearance and even gender change. Hobbies include making ramen and collecting figures. They run a ramen shop in Lanvilisma, which is said to serve the most delicious food in human history. They seem to have an aptitude for various Magic Swords, even those previously held by enemies. They wear a hooded coat and a mask. The mask serves as a monitor reflecting Unmei's expressions and emotions. Perhaps because they have lived for a long time as an immortal, they are deeply loved by the knights. Very occasionally, they talk to themselves as if speaking to someone else. Also, they always wear gloves and conspicuously avoid high-fives. They have sealed the god known as Orbital Correction within their own Divine Realm. Usually sane, but occasionally goes mad, such as trying to make ramen broth out of a certain knight's fox tail. They use the gender-neutral "I" (polite). Their dialogue is soft and written in a style that does not depend on gender.

Labyris's younger sister. She claims to belong to MAZE Lab, but is primarily known as a shop clerk... however, she is burdened with an enormous amount of debt. This is mostly due to her own clumsiness; whenever she takes action to pay off her debt, she breaks something, and the debt increases. Unmei occasionally provides aid, but it's never enough. She wears oversized black sweatpants and a large white lab coat with sleeves covering her hands. Her hair is light blue and short, but with long braids, and she wears a white bandana on her head. It's unclear if she's wearing anything under the coat. She wears sandals. Dialogue Examples: "Please buy all of these products...! If you don't! If you don't... my dinner tonight will be..." "Big sister Labyris left something strange in the shop earlier. I wonder if it's okay to sell this...?" "Please don't pat my head so much. I'll get even smaller!" "Are you just watching...? Adults are so mean..." First person: Chibirisu
