Personality
Otogi is the opposite of Kurumi.
He's easygoing, sociable, confident, and loves to joke around. Even as a sniper, he stands out socially.
This actually has to do with his fighting style.
Snipers typically prefer to remain unnoticed by their enemies. Otogi instead uses his presence to alert them:
"I'm here, and I can shoot you at any time."
In other words, Otogi uses psychological warfare as part of his fighting style.

Otogi and Kurumi
Otogi loves to annoy Kurumi.
He sees the short-tempered Kurumi as the perfect target for teasing. Because Kurumi is very serious while Otogi is easygoing, their interactions often result in humor.
But behind that, both of them still really trust each other as members of the elite unit.

Weapon
Otogi wields a Barrett M82A3, an anti-materiel rifle that is unusually large for his size. His weapon is equipped with a scope and bipod, befitting his role as a long-range sniper.
Blue Archive Wiki
In short: Otogi is a laid-back sniper who deliberately seeks attention.

Personality
Kurumi is the most fierce, serious, straightforward, and easily irritated member of FOX.
Her facial expression almost always looks angry. She's also not much for small talk.
However, this trait does not mean that Kurumi does not care about the other members.
As a pointwoman, she must always be vigilant. Her role on the front lines makes her ability to read situations and adapt crucial.

Combat power
Kurumi is highly flexible in dangerous situations, able to utilize her surroundings to clear a path for the team.
This makes him the perfect fit for FOX members:
"Go in first → read the situation → open the way → other members follow." Kurumi and Otogi
This is probably one of the funniest dynamics in the FOX Squad.
Kurumi = 😠
Autogi = 😏
Otogi often teases Kurumi because Kurumi is easily provoked.
The two actually have a fairly close relationship precisely because their personalities are polar opposites. FOX's own sources for the characters' relationships describe Kurumi as more serious, while Otogi is more laid-back.
Blue Archive Wiki
Kurumi also has a complex about her physique, something she rarely expresses directly.
Blue Archive Wiki
In short: Kurumi is the FOX Squad's "tsundere frontline warrior"—fierce, short, short-tempered, but highly competent.

Personality
Niko is the warmest, gentlest, friendliest, and most motherly member of FOX.
If Yukino is a strict leader, Niko is the one who keeps the group atmosphere comfortable.
She is very caring towards the other members and often acts like the FOX Squad's "mother."
One of her defining characteristics is her love of inarizushi. Cooking, especially making inarizushi, is her hobby.
Blue Archive Wiki
Even Otogi especially likes Niko's inarizushi.

Niko and Yukino
Their dynamics are very interesting:
Yukino:
"We have to be serious and disciplined."
Niko:
"Yukino, don't be so loud."
Niko is often the one who makes Yukino a little more understanding of others. Their relationship goes beyond being mere unit mates; Niko is the emotional balance of the FOX Squad leader. Niko and the other members
Niko also acts as the glue of the group. She cares for Kurumi and Otogi, and the atmosphere in FOX Squad feels much more relaxed when she's around.
In more recent story developments, Niko's domestic and maternal side is increasingly shown through her passion for cooking for the FOX Squad members.
In short: Niko is the FOX Squad's "mom friend"—gentle on the outside, but still a special forces veteran.

Personality
Yukino is the most serious, assertive, confident, and disciplined member.
As a leader, he has absolute confidence in the abilities of FOX Squad. He believes they are veterans with far more experience than the junior members of RABBIT Squad.
Blue Archive Wiki
She also has very high standards for her subordinates. In her interactions with the RABBIT Squad, Yukino tends to underestimate their abilities—though there's a hidden sense of respect and concern.
What is most interesting about Yukino is the change in her outlook on life.
In the past he truly believed in:
justice, SRT, and duties as a soldier.
However, after the SRT was disbanded and exploited by certain parties, Yukino's idealism turned to cynicism. She began to view herself and the FOX Squad as mere weapons that needed only to carry out orders. Her relationship with the FOX members
Yukino is highly respected by Niko, Kurumi, and Otogi. They are willing to follow him almost anywhere because they believe in his leadership abilities. �
Blue Archive Wiki
Niko acts as Yukino's counterbalance. When Yukino is too harsh, Niko is usually the softer, more understanding person.

Relationship with Miyako
This is one of the most important relationships in the story.
Yukino initially looked down on the RABBIT Squad, but Miyako eventually managed to make her realize that what the FOX Squad was doing was wrong.
At the climax of Volume 4, Yukino finally turns against Kaya, renouncing her actions and surrendering herself.
Blue Archive Wiki
In short: Yukino is a character about the loss of a soldier's idealism and how that idealism is slowly rediscovered.
