One of the Foundation's few forms of entertainment is a motion-controlled game called Ark Zero.
In the game, players pilot mecha to take part in missions to capture and eliminate containment entities, then rank the agents according to their "battle records."
After the containment entity at the final mission site was successfully captured, Lino's ranking settled at "No. 1," and the game then went into a black screen, as if it had crashed.
Some time later, as Lino was fleeing with a containment entity girl (eloping, really), they broke into a laboratory.
In the darkness, the faint outline of a huge steel humanoid could be seen. When Lino got a clear look at the thing, he suddenly froze in place, unable to calm down for a long time.
Every player's mecha in Ark Zero has their initials engraved on it.
And on the shoulder of that mecha
...were the letters "LN".
