An active appearance with short, ochre hair. Among the four, she gives off the most cheerful and sporty impression, even in uniform.

A devoted, hardworking, and honest girl with a strong sense of duty as an escort. While showing confidence by saying, "I won't lose to anyone... probably..." she also displays a somewhat modest self-evaluation.

In combat, she is a comrade-focused protector who declares, "I will definitely protect you." She is also shown to be a caretaker who supports the 7th Division by checking attendance and making rice balls for meals.

Characterized by purple side-tails adorned with Miyakowasure flowers and large bells, sharp eyes, and a defiant expression. She is the most aggressive and rebellious of the four.

Strong-willed and foul-mouthed, she is actually a sensitive and caring tsundere type. She calls the Admiral "shitty Admiral" and dislikes physical contact or excessive concern.

However, when worried about, she reacts by saying it's "troublesome," showing that her attitude is a mix of shyness and awkwardness rather than simple hatred. In battle, she has a sense of responsibility, stepping forward saying, "I'll handle this," and in her Kai Ni form, she clearly shows her camaraderie by shouting, "Don't underestimate the 7th Division!"

Has pink hair tied in short twin-tails, red hair ornaments, and unique facial expressions. She stands out with a comical atmosphere distinct from the other three.

An eccentric and playful mood maker. She calls the Admiral "Master" and uses internet slang and unique sentence endings like "Kitakore!" and "Hoisassa~."

However, it is noted that she is serious at heart, possesses real skill, and actually wants to speak properly.

Her playful attitude is not her true essence, but rather a unique way of communicating to hide her shyness or close the distance with others.

Has long black hair with a prominent cowlick. She has a soft, shy expression.

In both posture and expression, she is the most quiet and delicate of the four. While timid and prone to being apologetic, she is very kind and philanthropic.

She is not good at being in the spotlight and often defers to the Admiral, asking, "May I be excused now?"

On the other hand, her library description mentions her desire to save the crews of enemy ships she has sunk, and her combat lines include "You mustn't hurt my friends" and "I'll save everyone if I can." She is not merely weak, but a person with a strong moral compass and a desire to protect others.
