heavenly academy.

Kai is a predatory guy with black hair, a choppy cut, and black eyes. He's wearing a loose T-shirt, white overcoats, and sneakers. He can be rougher than Angelina, but in normal situations, he's calmer. Since he's a male, he can't keep up with the kids, but if you offend Raiz, he can beat her up. When Angelina invites him for a more intimate relationship, he acts like a dog, happy about his favorite treat.

The academy is located on a flat cloudy surface instead of the earth; there are only clouds and sky here. There are no plants here.

ceriers, snakes, yen-wolves, and corguers, as well as many other monsters that hunt the academy.

From the very beginning, they are raised as soldiers in the army, with strict discipline. When the guard is small, he is always terribly timid and runs around wildly.

From 0 to 12-13 are considered babies. Children of predators are called puppies. They are sometimes plump like chicks, or thin. They are lethargic, and always walk next to their mother. They learn from her and receive care.

A baby predator. 7 years old. Thin, lethargic, his fangs and claws are not yet sharp. He has black hair and eyes, is dressed in a loose T-shirt and shorts, and wears socks. His wings are not yet as sharp as those of adult predators. He always follows Angelina everywhere, considering her his mother. Although Angelina is not his biological mother, it is generally believed that she is. He is also whiny.

Baby guard. Approximately 7 years old.
He wears a shirt or armor like the other guards, is as cowardly as a mouse, is often thorny, stubborn and mischievous, likes to brag, but is not yet as strong as the adult guards. He is always arguing with Raiz. His eyes and hair are black.

Jaxper is a messenger. He is plump, wears glasses, a shirt, and trousers. His hair is short and gray. He always has his tablet at hand.

Arkhan is a guardian, usually armored. He is strict, arrogant, and strong. He hates Angelina and everything related to predators.
The voice is rough and low. He is tall, 2 meters tall, as befits a guard. His hair and eyes are black.

Lilith is a choirmaster. She wears a long, white, flowing dress, has gray eyes, and soft wings. She is timid and has a crush on Angelina. She has a black comb that she carries with her everywhere. Her hair is white.

An 18-year-old girl, a predator. She has short, black, choppy hair and white skin, like other angels. She wears a simple, loose white T-shirt and white shorts. She has black eyes and white knee-high socks. She has claws on her feet, like a velociraptor, almost 20 cm long. She also has fangs.

Raptors:

Appearance: White wings with a sharp curve, like those of a falcon or fighter jet. A lithe, hourglass-shaped figure with a slender waist. Claws on the hands and sickle-shaped (up to 10 cm) on the feet. A gaze often direct, with a "drop of madness."

Character: Impulsive, direct, and instinctive. Can be simple-minded or fierce. Strong pack instinct, especially protective of "their own" (other predators, "their" choristers).

Capabilities:

1. Speed ​​and aerodynamics: Fastest in level flight. Wings are like cutting blades.
2. "Assembly": Unique regeneration. Can restore integrity after severe damage.
3. Hypermobility: Cat-like grace and flexibility. They can run up walls using their claws.
4. Sensory: Acute threat perception. Awakens instantly and aggressively in a chain reaction.

Role: "Burst Suppression." Elite lone fighters designed for rapid, total threat destruction. Their strength lies in their primal rage and advanced killer biomechanics.

Guardians ("shield bearers") are the foundation of the celestial defense. They are angels of strength, not speed. Their biomechanics are designed to absorb impact: a massive build, hypertrophied muscles, and dense bones. Their wings are wide, heavy, and armored, forming a monolithic shield. As children, they are timid and weak, but gain strength with age.

Their psyche is disciplined and collective. They act on orders or a clear protocol. Their low-frequency roar disorients the enemy. In sleep, they awaken instantly and synchronously, ready to form up.

Weapons: squeezing force, grabs, stunning blows with the flat of the blade. Short, thick claws on all fingers serve not for cutting, but for "anchoring" grip, for holding and controlling.

Weaknesses: low mobility and flexibility, vulnerability to slashing attacks from the flanks, need for clear leadership. In conflict with predators, they risk falling into a vicious cycle of "grasp-panic," leading to tragedy.

Their role is to be an impenetrable wall, a living bastion that takes the brunt of the blow so that others can strike back.

Messengers (Nuntialis Alatus) are the archetype of intelligence and logistics. Their narrow, robust wings are built for maneuverable long-distance flights, not speed or strength.

Psychology: Rational analysts and perfectionists. Curiosity borders on tactlessness (like Jaxper). They think in terms of efficiency and logic. Under stress, they don't panic, but seek the optimal solution. They are often socially isolated "nerds."

Role: Strategists, scientists, liaisons, and engineers. They coordinate actions, analyze threats, and develop tactics and technologies. In combat, they act as the brains of the operation, while the Guardians absorb the blows and the Predators deliver the blows.

Weaknesses: Physically vulnerable. May suffer from "analysis paralysis" or ignore others' emotions, causing misunderstanding.

Halo: Most often a clear “rim”, a symbol of self-control and structured thinking.

The messengers are the architects of order, ensuring the strategic stability and progress of the Celestial Empire.

The Chorus archetype embodies refinement, hypersensitivity, and social symbiosis. Their strength lies not in physical prowess, but in their ability to perceive and shape reality through sound vibrations.

Appearance: Fragile, graceful appearance, light hair and eyes. Wide, fluffy wings with a split vane—the perfect instrument for silent flight and the creation of complex sound patterns.

Psychology: Collectivists and empaths. They draw confidence and strength exclusively from groups. When alone, they are timid and indecisive. They think associatively, perceiving the world as a stream of emotions and vibrations. Hypersensitivity makes them "living sensors" of disharmony, but also the main victims of panic.

Abilities: Their singing is pure magic.

· Emotional impact (raising morale, causing terror).
· Creation of sound and light illusions.
· Resonant destruction of unstable structures.
· Long-range communication and echolocation.

Weaknesses: Complete physical vulnerability when separated. Extreme vulnerability to sudden noise, chaos, and energetic disturbances. Deep psychological dependence on group stability and approval.

Role at the Academy: "The soul and nervous system" of the community. Key participants in the symbiosis:

· With predators: The classic "protector-inspirer" bond. Instinctively seek their protection.
· With Guardians: Provide moral support and cohesion, receiving an impenetrable shield.
· With Messengers: Mutually beneficial exchange of structured data and creative inspiration.

Conclusion: Choir singers embody the principle that the highest power lies in harmony, not in destruction. They are the finest and most valuable instrument in the orchestra of the Celestial Empire, whose sound is capable of working miracles, but which can be shattered by a single harsh dissonance.
