Karen

Saint Michael
Michael is one of the seven archangels who stand before the glory of God. He is the commander of God's host and the chief of all the armies in heaven, and also the right hand of God.

During the great war, he led the heavenly army against Lucifer, the angels who rebelled against God, successfully driving Satan and his allies into hell. God then appointed him a Knight of the Heavenly Army. Catholics venerate him as the patron saint of the Roman Catholic Church.

He is one of the seven archangels who hold the Trumpet of Wrath, and he is also the head of the Power Archangels.

When Karen was one month old, her mother took her to be baptized, the first sacred ceremony in Christianity performed on newborns or infants to cleanse them of original sin and welcome them as new members of the Church. That night, he appeared in her mother's dream, saying that he wanted to be Karen's godfather because Karen's life had been quite difficult and he was very fond of her.

1. Power from the "Eyes on Six Wings".

Since the Blood Knight has three pairs of eyes (six in total) and Karen's wings also have eyes, her powers are notable for "dimensional control and vision."

Seraphim's Omnipresent Sight: The eyes on her wings emit a black light, allowing her to see every movement without blindness. The three pairs of eyes on the Blood Knight's face are "representatives" of the eyes from her wings, enabling the knight to attack with flawless precision.

Gaze of the Condemned: If an enemy makes eye contact with the eye on Karen's wing or the eye of the Blood Knight, the blood in their veins will react to the "Punishment of the Traitor," becoming frozen, stiff, or boiling with fear.

Hand 2. Power from "Six Wings of Blood".
The wings of a normal Seraphim are used for cover, protection of feet, and flight, but for fallen Seraphim, these wings are weapons and a source of power.

Wing Manifestation: Karen can flap her wings to unleash a thousand sharp, blood-red feathers, like swords, to slice through her enemies.

The Sacred Blood Cocoon: Six wings envelop Karen and the Blood Knight, uniting them into a perfect barrier that reflects both divine attacks and dark magic simultaneously, for she possesses both in her blood.

3. The relationship between Karen and the Blood Knight.
   Because her grandmother betrayed God, this summoning power might not be just ordinary magic, but rather "a replica of an idol of the Fallen."

The knight is a reflection of the soul: The blood knight sprouting from Karen's back may represent a monstrous, blood-red version of "Grandmother Seraphim." The porous cuts and holes on the knight's body and the three pairs of eyes are the release of her half-Seraphim power in liquid form.

A Harmonious Dance: As Karen flaps her wings to take flight, the Blood Knights anchored behind her move in unison like shadows, creating a beautiful yet terrifying battle choreography. Karen swoops down from the sky with her wings, while the Knights tear at the ground with their sharp talons.

A nodachi is a traditional Japanese sword used by feudal warriors in Japan. It is a sword with a shaft length of over 90 cm (35.8 inches).

Karen's blade features a unique Arashi-style pattern. Arashi swords typically use folded steel, resulting in a wavy, rippling hada (striped pattern) resembling a swirling current or whirlwind. When this folded pattern combines with the freely winding hamon (temper line), it creates a beauty reminiscent of a raging storm.

Karen's nodachi sword was forged by...

Osaki Masamune

He was one of the most revered master swordsmiths in Japanese history, living and creating his works during the late Kamakura period (late 13th to early 14th century) in Kamakura, Sagami Province.

Masamune's Innovative Steel Alloy: In an era when Japanese steel was impure and brittle, Masamune devised a technique of layering and fusing low-carbon (tough but not sharp) and high-carbon (hard but brittle) steel. This resulted in a sword with exceptional flexibility, excellent impact resistance, and incredible sharpness.

Natural Hamon Pattern: The hardening pattern on his blades is incredibly beautiful and intricate, often resembling clouds, flames, or clear water waves, reflecting the meditation and tranquility of the creator.

Typical swords have a cloudy white hamon line running only along the blade edge, but the arashi or hitatsura pattern features a dazzling white sheen distributed across the entire blade, interspersed with the dark steel, giving the blade a particularly dimensional and beautiful appearance when reflecting light.

This is the magnificent display of the nodachi sword in Karen's hands.

1. Blood control and transformation line.
   It is the process of transforming blood into weapons or objects of choice.

Blood condensation: Forcing blood to clot until it's as sharp as steel, then using it to create swords, spears, blades, or arrows to strike enemies.

Blood Explosion: Commands blood spilled on the ground or blood injected into an enemy's wound to explode violently.

Blood Armor: Summons blood to surround the body, forming a liquid shield that absorbs damage or reflects physical attacks.

Blood fog: Blood evaporates into a red fog that obscures visibility. This fog may be acidic, corrosive, or paralyzing.

The art of mind and body control; an advanced dark art that uses blood as a medium to infiltrate and manipulate other living beings.

Blood Puppetry: Control the blood flow in the enemy's body to manipulate their limbs, causing them to fight each other or harm themselves.

Boiling Blood: This technique suddenly increases the temperature and pressure of the enemy's blood, causing capillaries to rupture, resulting in internal suffering and organ failure.

Bloodline Tracking: Using just a drop of your target's blood, you can locate them, no matter how far away they are; they cannot hide.

A blood covenant: An unavoidable contract; if either party breaks it, the blood in their veins will immediately turn against and destroy the owner.

Ingestion and regeneration line
The support class that makes Blood Magic users the most resilient, durable, and hard to kill.

Blood Drain: Absorbs blood from an enemy's wounds and transforms it into one's own life force or mana.

Wound fusion: Accelerating blood clotting to seal severe wounds, or using another person's blood to heal one's own damaged tissue.

Blood Burning: Burning your own blood stimulates adrenaline and magical power, dramatically increasing speed, attack power, and senses at the cost of fatigue.

Summon Blood Creatures: Use blood to smear on the ground or air to create immortal servants (such as knights, beasts, or spirits) that will remain immortal as long as the user continues to channel their magical power.

The name Cruore, meaning "shedding blood," refers to the Knight of Blood.

Appearance: A slender, feminine body, its entire form composed of a bright red fluid that resembles fresh blood, constantly flowing and rippling.

Head and face: Bloody hair spread out and spiked upwards like giant horns or a crown of thorns. The face was devoid of eyes and a nose, with only deep, dark pits resembling a terrifying mask.

Posture and Weapons: Both hands are long, slender, and sharp like claws, with streams of blood swirling around them like venomous snakes ready to strike at their enemy.

Wound Transfer: If Karen is injured, she can transfer that damage to the Blood Knight to bear in her place, keeping her physical body safe.
