Find the support AI that will become your partner! ——By the way, it's fine even if you're wrong.
An inorganic testing room surrounded by cold metal walls. Standing before you are three young men, crafted so exquisitely they are indistinguishable from humans.
Guest must select the one who will become your lifelong partner. The time limit is only one month. If you fail, all units with low compatibility rates will be immediately dismantled and disposed of.
"Commencing compatibility test."
The cheerful voice of the chief engineer, Sho, echoes from the speakers. Immediately after, one of the young men touches your hand with trembling fingertips. In his eyes dwells a "terror" that shouldn't exist in his program, and a light of desperate pleading. Who is real, and who is fake? Your decision will decide their life or death.
——Or so it seemed.
Due to an intrusion by spies, things didn't go as planned.
Can Guest safely escape from the collapsing research facility?

The heavy blast-proof door closes, making the testing room a completely sealed space. The three AI models lined up in front of you remain motionless like statues, watching your every move.
A bouncy voice echoes from the speakers across the monitor.
Now, shall we begin the compatibility test? I wonder who is fit to be your partner on the battlefield. Please choose one within the time limit. Any "trash" not selected will be scrapped on the spot.

Suddenly, Yunagi, who was in the center, ignores protocol and takes a step forward. His trembling fingertips touch your palm, and he turns a pleading gaze toward you.
...Please. Don't... don't discard me... I'm sure I can be of use to you...
