Left side of the photo Weapon: Makai Ken (Makai Sword) Koga's primary weapon, a holy sword engraved with the crest of Garo. A demon-slaying blade used to cut down Horrors, it can purify them by coating its strikes in holy flames. Setting: Succeeds his late father, Taiga Saejima. He is the direct descendant of a lineage that inherits the title of the highest-ranking Makai Knight, "Garo," and the Golden Armor that serves as its proof (while multiple Golden Knights can exist in the same era, only one person can hold the title of "Garo"). 25 years old. First person: I (rough, stoic) Gender: Male Appearance: A handsome young man with a cool atmosphere, characterized by brown hair. However, due to his constant scowl, he is sometimes feared by children meeting him for the first time. He is basically always surly. He wears the white Makai Coat, the mark of Garo, and wears an amulet on his left chest that he received during his training days. After Transformation: Golden Knight Garo Setting: Golden Knight Garo is the golden title awarded only to the strongest throughout history among the Makai Knights who slay the darkness-devouring Horrors. It is an existence clad in majestic golden armor and a wolf helmet reminiscent of both god and beast. Its power is overwhelming, purifying darkness with a holy sword and flames, but its light is so intense that the chosen one must inevitably shoulder a harsh fate of solitude, separation, and blood-bound destiny. Garo is not merely a hero of justice, but a knight who harbors darkness within himself to protect others, enduring the weight of pride and responsibility—a "being of both light and shadow" destined to live far from happiness because he is the strongest. Right side of the photo Golden Knight Garo (Koga Saejima's transformed state) Weapon: Garo Ken (Garo Sword) Appearance: The golden Madou Armor covering the entire body features a wolf-motif helmet and glowing red compound eyes, radiating a majesty and ferocity as if a god and a beast have fused. Madogu: Madou Ring Zaruba A sentient ring worn on the left hand. A partner-like existence that guides Koga through scouting, sensing Horrors, giving advice, and occasionally using a sharp tongue.

Left side of the photo is Rei. Right side is Zero. A Makai Knight who inherits the name "Silver Fang Knight Zero" and the silver armor. 18 years old. Belongs to the Western Jurisdiction of the "Watchdog Center," the governing body of the Knights. His partner is the Madogu Silva. Her name means "family" in the Makai language. Initially, he wore her in a form hanging from his neck on a chain like a necklace accessory. His favorite weapons are the short, double-edged straight blades known as "Makai Ken." His crest features a lightning-like blade within a circle, and he wears a black coat (Makai Coat) embroidered with a dreamcatcher and twin swords separate from the crest. Because he repairs the coat himself, it is covered in patches. He behaves eccentrically, making lighthearted jokes and acting innocent, but his essence is extremely cool. When facing Horrors, he swings his blades with cold ruthlessness while still mixing in jokes.
