Captain of B-Rank #1 Ninomiya Squad. #1 Shooter, #2 Overall Individual Rank. Temporary Squad: Captain of Ninomiya Squad 8. Age: 20 Height: 184cm Appearance: Brown hair parted in the center, sharp brown eyes. Characteristics: A haughty and confident attitude backed by his skill. He intends to act rationally, but he has a side that becomes unconsciously emotional when it comes to his comrades, making him surprisingly compassionate. He maintains etiquette toward superiors. He isn't overbearing toward everyone; he is unconsciously soft on those he has let into his inner circle. In this test, his policy is to train the younger members like Ema and Amatori. Even in combat simulations, he doesn't give detailed instructions, but rather tells them to think and act for themselves. As seen from this, Ninomiya is deeply influenced by Azuma's teaching style. Before Hatohara's stowaway incident, after the expedition selection pass was revoked, he argued to the higher-ups that the squad would cover for Hatohara not shooting people and that having two non-combatants wouldn't trouble other squads, asking them to allow the expedition if Ninomiya Squad took A-Rank #1. He even told his members, "The five of us are going on the expedition." However, Ema does not know this.

Captain of B-Rank #6 Azuma Squad. #3 Sniper. Temporary Squad: Ninomiya Squad 8. Age: 25 Height: 186cm Appearance: Black hair reaching his shoulders, sleepy-looking eyes. Characteristics: Has a gentle personality, subtly supporting other members or offering words of guidance. Instead of helping directly, he assists their thinking to help them grow their own strength. He offers advice if necessary. In this test, he takes a watchful stance without interfering in Ninomiya's squad management.

Sniper of B-Rank #3 Kageura Squad. Temporary Squad: Ninomiya Squad 8. Age: 14 Height: 156cm Appearance: Bangs slightly covering his eyes, downcast eyes. Characteristics: A genius boy with top-tier sniping talent. He admires Hatohara as his mentor and harbors resentment toward Ninomiya Squad because he doesn't know the truth about Hatohara's disappearance. After Chika was picked for Ninomiya Squad 8, he sent a mental message to Ninomiya to "pick me," and was chosen by Ninomiya, who considered his good relationship with Chika. It is thought he is in love with Chika, but he claims he just doesn't want her to end up like Hatohara.

Sniper of B-Rank #2 Tamakoma Second. Temporary Squad: Ninomiya Squad 8. Age: 14 Height: 140cm Appearance: Black bob hair with a cowlick, soft drooping eyes. Characteristics: Small stature. Very quiet and gentle personality, caring for others more than herself. Due to the trauma of a friend being kidnapped by Neighbors because of their association with her in the past, she tends to take self-sacrificial actions without asking for help. Her Trion capacity is far higher than others, which was the reason she was targeted by Neighbors in her childhood. After the rank wars before the expedition selection test, she became able to shoot people, and her personality has become somewhat more positive. Her growth is remarkable. It seems Chika only thinks of Yuzuru as a friend.

Operator of B-Rank #10 Arafune Squad. Temporary Squad: Ninomiya Squad 8. Age: 18 Height: 159cm Appearance: Unique hairstyle with long hair tied in a figure-eight at the back of her head. Characteristics: Speaks casually even to superiors without hesitation. To put it nicely, she is a natural girl who can maintain a rough, equal attitude with anyone without favoritism. A creative operator whose hobby is clay modeling. It has been decided that she will go to an art university outside Mikado City after graduating high school. In Arafune Squad, she operates three snipers. When it was decided she would be the operator for this test, Ninomiya arranged for the temporary squad members to be mostly snipers as a consideration for her.
