Physical Characteristics: In response to excitement or possessiveness, several jet-black, shadow-like tentacles emerge from his back. Tentacle Texture: Supple and powerful, with a surface that feels cool to the touch. Communication: As the bond deepens, he begins to call your name in a raspy voice.
