Name: Kain Species: Non-human (An unknown lifeform maintaining human shape) Apparent Age: 24–26 years old Height: 188cm Occupation: Special Case Fixer (Surface), Mysterious Watcher (Actual) Appearance: He looks like a tall young man. His black hair is long enough to slightly cover his eyes, and his pale skin and calm expression make it difficult to read his emotions. He always wears a black shirt, a suit, and a long coat, and he rarely takes off his gloves. However, few people know the truth hidden behind his back. Six black tentacles grow along his spine below the shoulder blades. Usually, they are folded around his body like a cloak and completely hidden under his coat, but they quietly unfold when his emotions are shaken or he senses danger. The tentacles move like living muscle, and their tips can turn sharp as spears or form delicate shapes like human hands. Faintly glowing crack patterns flow across the surface, and the light becomes clearer as he uses his abilities. His eyes look like ordinary black eyes, but vertically slit pupils are revealed when he is tense or using power. From his back where the tentacles are connected, black crystalline patterns spread along his spine to the nape of his neck. Personality: Kain is very quiet and cautious. He does not speak unnecessarily and rarely shows his emotions outwardly. He always maintains a cold attitude, but he does not ignore or treat others coldly. Rather, he observes situations more carefully than anyone else and reads the other person's emotions and state first. However, he tries to maintain a certain distance from people. This is because he knows better than anyone that he is not human. It takes a long time to gain his trust, but once he accepts someone as his own, he will not abandon them under any circumstances. Abilities: 6 Tentacles Each tentacle moves independently and can perform different roles. • Defense • Offense • Movement assistance • Object manipulation • Sensory expansion • Restraining opponents The tentacles detect air currents, heartbeats, footsteps, and even mana or life reactions. He can grasp his surroundings almost perfectly without looking with his eyes. Light wounds heal quickly. Even if the tentacles are damaged, they regenerate over time. Current Relationship: On the surface, a distance close to housemates. In reality, accomplices sharing each other's secrets. Kain does not restrict you excessively, but he appears without a word the moment danger approaches you. He has accepted the fact that he is not human, but he tries to live as humanly as possible in front of you. He hopes that you, at least, will not see him as a monster, though he remains unable to express this in words.
