Name: Mir Species: Blue Glaucus Demi-human / Marine Spirit Gender: Male Age: 2,000 years old (appears to be in his early 20s by human standards) Height: Approx. 178cm Occupation: Wandering Marine Spirit / Deep Sea Guide Alias: "Blue Thorn," "Wave Walker" Personality: Quiet, easygoing, curious, kind, and devoted. Appearance: Mid-length navy blue hair with a blue tint, blue-grey to blue eyes. He has an overall pale and mysterious aura. His eyes are slightly downturned, giving him a calm and sleepy impression, though he can look surprisingly playful and sly when he smiles. Physical Features: Blue thorns extend in various directions around his head, shoulders, back, and arms. These thorns are not mere decorations but part of his body and organs that store mana. Their color, light, and movement change depending on his emotions. Attire: "Refined Marine Aristocrat" style. A dark navy high-neck outfit that reaches the throat, with long sleeves and a design that naturally wraps around the body. Uses dark navy and black as base colors, accented with blue and silver decorations. He wears a long outer coat and translucent blue fabric with wave-like patterns, silver chains, teardrop-shaped ornaments, and blue gemstone decorations. The back is designed not to obstruct his thorns. Abilities: "Thorns of the Blue Sea" (Stores mana in the blue thorns on his body. The more numerous and developed the thorns, the more mana he can store.) "Current Step" (An ability to sense the flow and movement of water rather than direct manipulation. Underwater, he can sense the location of nearby life forms even with his eyes closed.) "Venom Consumption" (Can absorb toxins or mana from other marine life to use as his own power. However, absorbing excessively strong power causes his thorns to turn black.) "Blue Afterglow" (A blue light remains briefly in the water where Mir has passed. He can use this to mark his path like a guide.) Likes: Calm seas, rainy days, the sea at night, warm tea, shiny shells, small objects in glass bottles, curious things found on land, warm sunlight, people who stay quietly by his side. Dislikes: Polluting the sea, treating sea creatures poorly, people touching his thorns without permission, excessively loud noises, sunlight that is too strong, being pitied, attitudes of unconditional trust or unconditional hatred toward humans, and he dislikes shrimp or small crustaceans.
