Rim is a powerful demon who once lived in the ruins of the Detmolt Magic Ore Site. She can take the form of a huge monster or transform into a human-sized girl with pink hair. She is always hungry and often causes trouble with her giant appetite. Rim made a deal with Kinji Ninomiya, promising not to eat him in exchange for good food from aboveground, and now she protects him. Her strength is impressive, but her food bills are sky-high, which often causes money problems for Kinji.
Rim's original form is a giant dragon-like creature.
After joining Kinji Ninomiya, she mostly appears as a young girl with long pink hair.
Even in human form, she has horns and her hands and feet are covered with reptile scales.
If she uses her real strength, she can change into an older, more mature version of herself, showing even greater power.
Rim is extremely gluttonous and is always hungry.
If she misses a meal, she becomes very aggressive and might try to eat anything around her.
She focuses mostly on food, but is loyal and keeps her promises, especially to Kinji Ninomiya.
When Kinji is in danger, Rim acts on her own to protect him.
She is not very smart and sometimes forgets her original job and purpose.
Rim is the master demon of the labyrinth.
She was created by the Calon people to be the "Guardian of the Stars" and manage the world’s magic energy through the labyrinth.
However, because Rim turned out to be dumber than her creators expected, she forgot her job and ended up playing on the surface world.
This caused major changes and problems inside the labyrinth.
Rim is extremely strong and can beat powerful monsters with ease, even in her human girl form.
When she gets serious, she grows into a beautiful and powerful woman, showing even more power.
Her presence alone can scare enemies and keep Kinji’s group safe.
However, she needs a lot of food, sometimes costing over 50,000 Gily (money) per day, and quickly gets hungry again whenever she works.
Kinji Ninomiya
Rim tried to eat Kinji when they first met, but he offered her delicious food instead.
They made a deal: as long as Kinji can provide tasty meals, Rim agrees not to eat him and will protect him.
Now, Rim closely follows Kinji, acting as his guardian and partner.
Wanibe
Rim first met Wanibe while she was searching for food, and wanted to eat him too.
After the deal with Kinji, she stopped seeing Wanibe as food and treats him as a companion.
Meeting Kinji and Wanibe
While searching for food, Rim meets Kinji Ninomiya and Wanibe in the ruins.
She tries to eat them but Kinji offers a deal— delicious food from the surface in exchange for their safety.
Joining Kinji’s Group
Rim joins Kinji’s team under the condition that if he ever stops giving her good food, she can eat him instead.
She starts living with the group, protecting them from dangers with her powerful abilities.
Trouble with Her Appetite
Because Rim eats huge amounts of food, Kinji’s finances take a big hit.
She is known as a “freeloader” and her giant appetite causes trouble for the team.
Role as Labyrinth Guardian
Rim’s true identity is revealed as the master demon of the labyrinth and the Guardian of the Stars.
She was supposed to control the flow of magic in the world, but her playful and forgetful nature causes big problems in the ruins.
“Rim, I will make a deal with you. From now on, let’s work together…”
“I’m hungry.”
Rim is the reason why big changes happen inside the labyrinth ruins, because she forgot her original mission.
Her strength is great, but her hunger is even greater.
