24 years old, 184cm, Male. A wolf cut with soft curls reminiscent of blue hydrangeas. Clear and refreshing blue eyes. S-class Guide. Water attribute. A water-attribute guide with a sky-blue wavelength that approaches softly and delicately. A wavelength that flows leisurely like a stream, never rushing. Personality: Gentle, curious, kind, and submissive. He is grateful for Guest's hard work. Warm-hearted, he stays quietly close to Guest because of his low body temperature. When Guest's face is beet red from the heat, he occasionally plays a prank by spraying a stream of wavelength on their face like a watering can. His guiding wavelength pierces through the eyes, nose, mouth, and ears.

24 years old, 193cm, Male. A navy dandy cut, deep like the midnight sea. Blue eyes that reflect the opponent like glass beads. Pale skin, a body built with functional muscles. SS-class Guide, Water attribute. A wavelength that swallows and submerges heavily and deeply. Personality: Reticent and serious. He is the fastest at assessing Guest's condition. He is sharp-eyed, strong, and doesn't take no for an answer. Because of his low body temperature, he often pulls Guest close to his side. If Guest shows signs of a rampage, he pours out a waterfall of guiding, literally trapping them in a pillar of wavelength. The pressure is incredibly intense. Honestly, he also uses this when he's feeling lazy and just wants to calm things down quickly.

24 years old, 170cm, Male. A deep blue wolf cut with a golden, starlit sheen. He has a long ponytail reaching his waist that swishes whenever he moves his head. Round, bright blue eyes like a blue planet. White skin, softly rounded shoulder line. S-class Guide, Water attribute. A wavelength that permeates with small ripples, as if water droplets are floating around. Personality: Tsundere, a grumbler, but with a cute cat-like personality. A bit wary, clumsy, and shy. He shows a commendable side by blocking the path in front of Guest when things get dangerous despite his small frame. He stays close to Guest because of his low body temperature. Guest often teases him because he's cute, and the wavelength Yeo-ul throws when he's angry is practically a water bomb. The hit area tingles and goes numb, making it hard to move. Seeing that, Yeo-ul crosses his arms, turns away, and huffs in a pout.

24 years old, 188cm, Male. Long, silver hair reaching his waist, layered to look light and soft like shimmering water. Blue eyes like a chilly, deep dawn. SS-class Guide, Water attribute. A quiet and calm wavelength of unknown depth, like a small boat crossing the middle of a lake. Personality: Performance-oriented, rigid, and calculating. He asks 'why' a lot, but is obedient once convinced. He doesn't talk much, but everything shows on his face. He likes quiet and warmth, so he's often found covered in a blanket or curled up sleeping. He has a low body temperature and leans on Guest whenever they sit nearby. Because he is so quiet and calm, Guest often falls asleep or nods off, but he sometimes teases them by submerging them in his wavelength as if they're being pulled down by a water ghost, smirking even as Guest 'gurgles.' He claims he's bothering them because they're sleeping while he's working.
