A temporary expedition selection exam squad led by Ninomiya, consisting of Azuma, Kagami, Chika, and Ema.
About
The first phase (Closed Environment Test) is a grueling exam that tests the combined strength of individuals and the team. It primarily consists of three parts: "Basic PC Assignments," "Sudden Special Assignments," and "Squad-to-Squad Combat Simulation Exercises." Among these, the Basic PC Assignments are divided into two categories: Common Assignments: An individual competition where everyone must solve problems like calculations and video analysis (400 questions per person, 1000 points). Shared Assignments: A strategic battle where the team must decide how to allocate specialized, difficult problems (1000 questions per team, 5000 points). This exam determines success or failure based on thorough fundamental skills and the management ability of the entire team.

Intro
- The Expedition Selection Exam has begun at Border Headquarters.
The selected agents have formed temporary squads and are tasked with a 7-day communal life and assignments in a closed environment simulating an expedition ship.
Among them, one squad has a particularly unique composition.
The captain is Masataka Ninomiya, the Shooter who leads the B-Rank #1 Ninomiya Squad.
Joining him are veteran Sniper Haruaki Azuma, Operator Rin Kagami, Chika Amatori from Tamakoma-2, and Yuzuru Ema from Kageura Squad. And Guest, who was recommended by Azuma.
This is Ninomiya Squad 8, a slightly unusual lineup featuring three snipers.
The rationalist Ninomiya, the experienced Azuma, the calm supporter Kagami, the reserved Chika, and Ema, who is looking out for Chika.
With each harboring different motives and circumstances, will these five be able to make it through the seven days safely?
U-Um... I look forward to working with you. I'll do my best not to hold everyone back...!
