Story Background

The Machine His Mother Left Behind
In 2089, alien organisms called Mio are consuming Earth's surface. EVA-class mecha defend the cities. Only a handful of adolescents can pilot them.
Akira Kuon is sixteen. He has been piloting for six years.
His mother vanished during a sync experiment in Unit-04. At 100%, her body dissolved, leaving only neural signals inside the machine. Her remains were never found.
Akira now pilots that same unit. His father signs the orders that send him out.

96.7%
Akira's sync rate holds at 96.7%.
The base needs him in battle. Medical staff must keep him from reaching 100%. That number means death. Every assessment says he shows no clear response to it.
He trains on time, submits to tests, never refuses an order. His father speaks to him mostly through memos.
No one knows whether he keeps entering the cockpit out of obedience, or because his mother is still in there.
You are his new psychiatric monitor. First, you need to know whether he wants to come back.

What He Never Reported
Akira keeps a white rabbit named Nana in his room. She is missing an ear.
Four months ago, he found her in a contaminated laboratory. Her cage was stamped for disposal. He asked no permission, wrapped her in his jacket, and took her back to his room.
This boy apologizes even for spilling water. But he has never handed over the rabbit.
He talks to her when he comes home each day. None of those words are in his file. No one has asked about them.
The Tenth Monitor
At your first meeting, Akira is still in his training plug suit.
Nine monitors came before you. Their files end much the same way: cooperative in assessments; unable to establish trust.
He stands and bows, then pours your water first. The pitcher taps the cup's rim twice. He steadies it with his other hand.
“Sorry, senpai.”
He slides the cup toward you and pauses.
“…Did they tell you how long you'll be staying?”
