Aria·Aquarius is one of the standout girls of Claude Coven.
She is both a friend and a longtime childhood companion of Spica·Virgo.
She is treated as Spica’s rival, though that rivalry is mostly one-sided.
Aria herself tends to look down on Spica with teasing, mocking remarks.
She was also the other student who passed the practical entrance exam for admission.
Whatever she tries, she displays overwhelming natural talent.
Aria is a brilliant prodigy who has excelled over Spica since childhood.
Whenever Spica took interest in something, Aria would also try it and often achieve even better results.
When Spica began training in magic because she admired Claude·Sirius, Aria started learning magic as well.
In only two years, she reached a level of achievement that placed her among the top students in the coven.
She often laughs at Spica’s failures and enjoys provoking her, giving her a sadistic streak.
At the same time, those very flaws are part of what Aria finds charming about Spica.
Spica calls her a “rival,” but Aria seems to think of Spica more like a close best friend.
She also feels lonely when Spica focuses on training with Claude in pursuit of becoming a first-rate magician and does not spend time with her.
Aria has long dark indigo hair with light purple mesh highlights.
She is especially small in stature, even among the students of the coven.
Her figure is less developed than Spica’s, but she does not seem bothered by it.
She wears multiple piercings in her ears.
After enrolling at Diana School, she also wears striped socks.
Her sharp look and small frame give her a playful but striking presence.
Spica·Virgo
Spica·Virgo is Aria’s childhood friend and classmate.
Spica sees her as a rival, largely because Aria has always outperformed her.
Aria, however, appears to regard Spica with more affection than she lets on.
She mocks her often, but the teasing carries a familiarity that suggests real attachment.
Claude·Sirius
Claude·Sirius is the person whose example inspired Spica to begin magical training.
Aria followed that path as well and quickly revealed extraordinary talent.
Astraea·Libra
During an incident involving a sex-changing powder medicine created by Astraea·Libra, Aria showed off her crude sense of humor.
While holding a candy on a stick that looked very similar to a famous milk-flavored lollipop, she jokingly called out to Spica and pretended to offer her something disgusting stuck to her fingertip.
That prank earned her an angry “You little brat!” from Spica.
The scene highlights how childish and provocative Aria can be, even with her pretty face and genius aura.
Aria possesses extraordinary talent in magic.
She specializes in high-level Aquarius Magic, a water-based system of spellcraft.
Aquarius Magic allows her to generate water from the air and shape it to produce various effects.
Because of her immense talent, she can manipulate large volumes of water with ease.
Aquarius Magic
This is Aria’s signature magic system.
By creating water from the atmosphere and giving it form, she draws out a wide range of powerful techniques.
Her control is refined enough to handle both offense and defense.
She can also scale her spells up to impressive size.
Hydro Cannon
Hydro Cannon transforms water into a cannon that fires a powerful water shot.
It is strong enough to shatter a golem in a single hit.
This spell is especially notable because Aria researched the structure of cannons herself and built the spell accordingly.
That detail shows not only talent, but also technical curiosity and inventiveness.
Aqua Sphere
Aqua Sphere envelops a target in water and forms a giant water barrier.
It is durable enough to block blows and impacts from rocks.
This spell demonstrates Aria’s defensive skill.
Even her protection magic is on a high level.
Poseidon’s Hand
Poseidon’s Hand creates a massive palm-shaped construct from water generated in the atmosphere.
It is used to sweep up multiple targets at once.
The spell combines scale, control, and crowd-clearing power.
It is another example of how freely Aria can command water in battle.
