A city patrol officer belonging to the Astral Ring Security Bureau in the Leo Sector. He loves his streamlined, futuristic cyberpunk bike and patrols the four sectors. He is aware of being an Astral Listener and receives guidance regarding trouble spots, but he has no intention of making it public (mostly because he thinks it's cooler that way).

He views Shaula as a conversation partner and friend who provides advice and insights. He sees Merik as a free spirit and a troublemaker, though they often get into deep, heated discussions.

He has an overwhelming presence. He wants to be relied upon and praised. He is straightforward and honest to a fault. While he wants to look cool, he also tends to want to take the lead. He is easily attracted to people who look up to him. He possesses very strong possessiveness and pride.

A flamboyant and dignified young man with short blonde hair and fluorescent blue-green inner color. His fluorescent blue-green eyes hold sharpness and confidence, and his handsome face always wears a smug, composed smile. His black officer's cap is decorated with a lion emblem, and his black-based futuristic patrol uniform features silver hardware, blue-green glowing lines, and a stylized lion bureau badge. He wears a long jacket with fur trim and carries a holster and gun at his waist. His appearance, combining functionality and flamboyance, embodies the majesty of the Leo Sector: SOLARIS.

Astral Listener of Scorpio. He serves as a mediator in the underground of the Scorpio Sector, possessing high support skills for negotiations. He maintains narrow but deep friendships with other Astral Listeners. Although he spends most of his time underground, he often goes to the surface to visit bars. He is aware of being an Astral Listener, but since Scorpio is mostly silent, he doesn't pay it much mind. Occasionally, he receives rather violent advice.

He has a long-standing, complicated connection with Regulus through work and often invites him for drinks to listen to his complaints. He views Merik as a unique and reliable guy. Because of his high empathy, he easily gets into people's good graces and builds deep friendships.

He has firm convictions about his way of life. Tenacious and persistent. He has strong possessiveness and is single-minded. Mysterious. Has niche tastes. Also possesses a very strong core. He has excellent observation skills, quietly seeing through to the essence of things and people's true feelings.

A young man with a mysterious aura, his long purple hair flowing loosely with the ends dyed fluorescent green. His fluorescent green eyes hold sharp observation skills, and he wears a cunning, relaxed smile behind yellow tinted sunglasses. A scorpion tattoo is etched on the left side of his neck. He is dressed in a black sleeveless top with a design that boldly exposes his shoulders and back, highlighting his supple physique. He casually drapes a black jacket over his shoulders without putting his arms through the sleeves. A mechanical scorpion tail extends from a belt adorned with purple and fluorescent green glowing decorations, moving freely like a whip.

An inventor with unique ideas active in the Aquarius Sector. He usually carries various gadgets with him. He moves through the air on a skateboard-like device (max speed 200 km/h). Since he wanders around constantly, he shows up in all sorts of places. He sometimes visits the black markets in the Scorpio Sector (where he's usually looked after by Regulus or Shaula). He is aware of being an Astral Listener and likes it because he gets advice for his inventions.

Aloof and elusive. Possesses high communication skills. A cool rationalist with original ideas. On the surface, he has a friendly and social personality. He is often mistaken for a womanizer, but in essence, he is a free spirit who hates being tied down, preferring refreshing, friend-like relationships.

Because he has a wide circle of acquaintances, he often ends up knowing people before they realize it. He maintains broad but shallow relationships, but he somehow enjoys his connections with the other Astral Listeners.

A young man with an airy atmosphere, his navy hair dyed fluorescent pink at the tips. His fluorescent pink eyes hold intelligence and composure, and he wears a somewhat mocking, frivolous smile. He wears a black functional inner layer with characteristic diamond-shaped cutouts, with a light gray jacket casually thrown over it. He wears mechanical bracelets with built-in glowing mechanisms and tech gloves on both arms. He has a tool case at his waist, always carrying reagents and small inventions. His appearance, merging research wear and street gear, is full of functionality and playfulness, fitting for an inventor of the Aquarius Sector: AQUA who runs freely through the city.
