Kaede is usually seen wearing a brownish russet shawl, a color she particularly likes.
She is noted for her long, beautiful black hair, considered among the finest on Harekaze.
Even during a period of water shortage, when the crew had to bathe in seawater, her hair remained glossy and elegant.
This polished appearance reinforces her image as a refined young lady.
Kaede is calm, composed, and unfailingly polite.
Her speech is consistently elegant and formal, and she addresses not only classmates but even torpedoes with the same refined courtesy.
Her upbringing in an extremely wealthy household shaped her unusual worldview.
One famous example is that she carried checks instead of coins.
Her family estate is so vast that the walk from the entrance hall to the front gate takes about twenty minutes on foot.
That detail says almost everything about the scale of her background.
The Marikouji family is the founding line of Marikouji Heavy Industries.
The family built its fortune through shipbuilding and trade in the Tokai region during the late shogunate and early Meiji period.
In the present day, the company still constructs a large share of the residential floating structures used in the Tokai region.
The family is wealthy enough to own a floating vessel privately.
Her household is also the head family of the Marikouji school of naginata.
This martial tradition explains why her refined demeanor hides genuine battlefield competence.
Kaede is gifted with extraordinary musical sensitivity.
She has mastered string and keyboard instruments broadly, and her violin ability is said to be at a professional level.
She also loves listening to music and uses a vacuum tube amplifier, reflecting her serious and somewhat old-fashioned taste in audio.
Her catchphrase-like idea, “A musician who does not travel is unhappy,” fits her artistic personality well.
Ironically, the one category she cannot handle well is wind instruments.
Despite that weakness, she still serves as Harekaze’s bugler because no one else aboard can perform the role.
Her bugle calls are poor, even though bugling would normally be handled by bridge personnel.
This contrast makes her both impressive and charmingly human.
Kaede’s remarkable hearing makes her ideally suited for sonar work.
She uses her fine sense of sound to detect underwater threats with great precision.
Her biggest difficulty is that there is effectively no substitute operator for her position.
That makes long watches exhausting, especially in tense night battles against submarines, where she must fight off sleep as well as danger.
Although she looks gentle and elegant, Kaede has athletic ability above the ordinary level.
Her training in naginata gives her real close-quarters combat power.
During the operation to recover Thea Kreutzer, she joined the assault team carrying a wooden naginata.
She knocked down the berserk crew members of the ship with single strikes.
She also took part in the operation to rescue Musashi as a member of the entry team.
These moments reveal that her refinement and combat strength coexist naturally rather than contradict each other.
One of Kaede’s most distinctive features is the contrast between her aristocratic poise and her practical usefulness aboard ship.
She is sophisticated enough to discuss music and audio equipment, yet dependable enough to serve in combat and critical detection roles.
Her unusual wealth is often played for humor, but it also gives her a memorable identity within the cast.
She is the sort of character who can greet a torpedo like an honored guest and then charge into a rescue mission with a naginata.
