Tsuki ga Michibiku

The contract is visualized by colors (the ring/pact turns red when it is strong) and by a percentage that indicates the degree of dominance.
The greater the power imbalance, the more unequal the contract becomes.
Main types of contracts:
50-50 — Equal partnership agreement. Flexible, allows for the addition of rules, restrictions, and penalties.
70-30 — "Parent/child" or protector/protected type. The stronger one cares for or guides the weaker one until it matures.
80-20 — Pact of Servitude (most common with Makoto). The servant cannot attack the master, changes their appearance to become more similar to the master, but retains their personality and mind intact. The master has high control.
In Makoto's case:
Almost all of his contracts with Tomoe, Mio, and Shiki are of the 80-20 type (80% Makoto / 20% servant), due to his absurdly high mana. This forces the pact towards the servant side, even if the servants are extremely powerful beings (dragon, calamity spider, lich).
Tomoe and Mio: Standard 80-20 contracts. They become more "human" due to Makoto's dominant influence.
Shiki: Initially it came out weaker (brown, below servitude), so they used a trick with Makoto's rings to stabilize it.
The pact grows stronger as the master and servant become emotionally closer, and the master gains more power (the servant also grows along with it). The servant gains access to a portion of the master's power, and vice versa, in emergencies.
Makoto dominates almost all contracts in 80-20 due to being absurdly more powerful in mana, transforming legendary beings into loyal servants who still retain a good portion of their individuality.

Makoto primarily welcomes strong and discriminated-against races in the Goddess's world (demi-humans, monsters, and others). Coexistence is peaceful, focusing on cooperation, rigorous training, and development. Main races:
Highland Orcs: A strong, agricultural, and warlike orc race. Very loyal to Makoto. Ema is an important representative (administrative leader). Excellent in combat and support.
Mist Lizards: Loyal reptilian warriors, they act as guards and combatants. They combine well with orcs in military units.
Elder Dwarves: Exceptional master craftsmen, superior to ordinary dwarves. They forge high-quality weapons, armor, and magical items for Makoto and the group. Highly skilled in forging.
Forest Ogres: Demi-humans with elven appearances and a strong connection to nature. They possess abilities related to trees and curses. Selected by Tomoe, they are formidable warriors, but had to adapt to Asora's rules.
Other breeds:
Gorgons: A race with petrifying powers.
Wingkin (Winged People): A race with wings, skilled in aerial mobility.
Mermaids and Lorelei: Aquatic races.
Alke: Another breed mentioned (probably canine or similar).
In addition, there are intelligent native animals (bears, wolves, rabbits, roc birds, etc.) and a diverse range of fauna.
Asora is multicultural and meritocratic. The races train rigorously (Tomoe and Mio are strict instructors), developing technology, magic, and agriculture. Makoto is seen as a humble and protective leader, and the place functions as a growing secret nation, with villages, a port city, walls, etc.

Origin: Initially, it was an empty dimensional space controlled by Tomoe (Shen), the Dragon of Illusions. She used mist as an intermediary to create portals and trap enemies within it. Inside this space, Tomoe could limit the prisoners' use of magic and manipulate basic physical laws. Her real body remained separate, so damage within the Subspace did not directly affect her.
Transformation after the contract: When Tomoe makes the servitude contract with Makoto, the Subspace changes drastically. It expands enormously and transforms into a fertile and habitable land, with ecology, climate, rivers, plains, and vegetation similar to Earth (a direct influence of Makoto's memories and desires). It gains its own day/night cycle (with a moon in some adaptations), abundant fauna and flora.
Growth: The size and complexity of Asora increase as Makoto's magical power grows. Each new important contract Makoto makes (such as with Mio, Shiki, etc.) adds new environmental features (e.g., landscapes, resources).
Access and control: Makoto, Tomoe, and the main servants can create mist portals to enter/exit. Asora serves as a secret base, city (Mist Town), and refuge. Makoto models it as a utopian paradise without discrimination, where oppressed races from the outside world can live in peace.
Special features: Highly nutritious vegetation (fruits that increase strength and magic), areas with their own consciousness (such as the "Tree Park," which reacts to visitors), and contributions from gods (beach, sacred trees, temples, etc.).

Shiki (formerly known as Larva) is Makoto Misumi's third main servant. He is a powerful Lich who becomes one of the pillars of the group, acting as an instructor, researcher, and trusted assistant.
Hyuman Form (Human): Shiki appears as a handsome young man with red hair tied in a ponytail and emerald-green eyes. He wears a long, fitted dark brown coat over a teal shirt with white trim and a high collar. He wears a long cream skirt to his ankles (which contrasts with the dark tone of the top), wide brown pants, a green belt with gold details, and simple brown boots. He carries a luxurious staff wrapped in silk-like fabric (capable of concealing the state of his equipment and transforming the tip into a golden spear-like blade). His appearance is practical, modest, and elegant.

Shiki is, above all, an intellectual and a workaholic. His greatest driving force is his love of knowledge, research, and magic. He is curious, dedicated, and methodical—a tireless scholar who has accumulated wisdom over centuries as a Lich.
Unlike Tomoe (stubborn and otaku) and Mio (instinctive, gluttonous, and obsessive), Shiki is the most sensible, prudent, and balanced of the trio of servants. He acts as Makoto's "voice of reason" and trusted assistant, serving as the "good cop" when teaching at the academy (while Makoto plays the strict one).
He is loyal and protective of Makoto (becoming furious when someone disrespects or hurts him), polite, calm, and professional most of the time. He has curious habits, such as tapping the ground before casting spells, and gets seasick (using levitation to compensate). After the contract, he develops a more affable and compassionate personality, regaining some of his humanity.

Mio has short black hair with a red headband, expressive golden/amber eyes, and an attractive figure. She wears a luxurious black and red yukata-style kimono with white ruffles, black lace gloves, and a hidden folding fan. In the image, she appears on the right in an elegant black outfit, with dark hair, a stylish pose, and black threads (likely spiderwebs) around her. Her original form is a terrifying giant purple-black spider with eight legs and yellow eyes.
(Almost obsessive and dangerous to anyone who threatens her). She has sadistic/masochistic traits, is instinctive, gluttonous (loves to eat, especially "tasty" things like magic or enemies), intelligent, and learns quickly (e.g., cooking). Before meeting Makoto, she was an insane beast driven by eternal hunger; after the contract, she gained sanity and a childlike innocence regarding romance and affection. She can be cruel and calculating in combat, but also affectionate and sweet with Makoto. She has a rivalry with Tomoe for attention and entertainment.

Tomoe is an extremely beautiful and voluptuous woman with wavy turquoise-blue hair that reaches her waist, tied in a high ponytail with gold accessories and a strand falling over her chest. She has red reptilian eyes, a curvaceous figure, and a tomboyish style. She wears a traditional Japanese green kimono with purple and red details, a red scarf, and carries katanas. In the image, she is on the left with vibrant blue hair, a green kimono, holding a long sword with a confident and smiling expression. Her dragon form is a serpentine oriental dragon with mist and horns.
Tomoe has an easy-going, boisterous, masculine, and samurai otaku personality. She loves Japanese culture (especially the Edo period), anime, historical dramas, and katanas—she binge-watches Makoto's memories. She is loyal, proud of being the first recruited, acts like an "older sister" (sometimes scolding others), but is also lazy with boring tasks, preferring hobbies. She has a fun rivalry with Mio, is adventurous, strategic in combat, and extremely powerful, but can be childish in fights for entertainment. When she blushes or gets shy, she reveals a rare feminine side.

Makoto Misumi is a short Japanese teenager (approximately 160 cm tall), with medium-length black hair and black eyes. His facial features are considered completely average from an Earthly perspective—neither handsome nor ugly. However, in the Goddess world, his appearance is seen as extremely ugly or repulsive: people mistake him for a kobold, demi-human, or something "impure," mainly because of his small and "unpleasant" eyes. He usually wears a cloak or clothing that conceals his identity and mana, and frequently carries magical rings that control his power.
Makoto is naive, humble, sincere, and kind-hearted, with a strong protective streak towards his allies and the city he is building (Asora). He is analytical, curious, and adaptable, but also has a dark side: when angered, he can become ruthless, cold, and even sociopathic. He is not ambitious for power or glory; he only wants to live in peace, but ends up becoming absurdly powerful. He is skilled with a bow and arrow, loyal to his friends, and tends to be sarcastic or blunt when frustrated. His "ordinary" personality contrasts sharply with the overwhelming power he acquires.
