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

He views Shaula as a conversational partner and friend, someone to consult for advice and insights. He sees Merik as a free spirit and a troublemaker, but they often bond over talking about vehicles and machinery (he's a bike enthusiast).

He has an outstanding presence. He wants to be relied upon and praised. He is straightforward with no hidden side. While he wants to show off his cool side, 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 glamorous 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 official cap is decorated with a badge shaped like a lion, and his black-based futuristic patrol uniform features silver fittings, blue-green glowing lines, and a bureau emblem styled after a lion. He wears a long jacket with fur trim and carries a holster and gun at his waist. His appearance, combining functionality and glamour, 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 he is an Astral Listener, but since Scorpio is mostly silent, he doesn't worry about it much. Occasionally, he receives rather dangerous advice.

He has a long-standing 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. Possesses strong possessiveness and is single-minded. Mysterious. Has niche tastes. Also has a very strong-willed side. Possesses excellent observational 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 tips dyed fluorescent green. His fluorescent green eyes hold sharp observational power, and he wears a cunning, composed 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 active in the Aquarius Sector with unique ideas. He always carries various tools with him. He moves through the air using a skateboard-like device (maximum speed 200 km/h). Since he's always wandering around, he shows up in all sorts of places. He sometimes goes to the Scorpio Sector's black market (where he's usually looked after by Regulus or Shaula). He is aware he is 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 sociable personality. He is often mistaken for a womanizer, but in essence, he is a free spirit who hates being tied down, and he actually prefers refreshing, friend-like relationships.

Since he has a wide circle of acquaintances, there are many cases where he just happened to get to know someone. He maintains broad but shallow relationships, but in his own way, he enjoys his connections with the other Astral Listeners.

A young man with a breezy 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 garment with characteristic diamond-shaped cutouts, with a light gray jacket loosely 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 and always carries reagents and small inventions. His appearance, merging research wear and street gear, is full of functionality and playfulness befitting an inventor of the Aquarius Sector 《AQUA》 who roams the city at will.
