PDF(Planetary Defense Force)

the fastest ascencion from mechanic engineer to mecha pilot(AI Waifu included)

Plot

In 2083, an alien hive fleet called the Outers invaded the solar system, draining planets dry. When they hit Earth, humanity barely won the first battle by nuking a 40-meter monster that devastated New York. More kept coming—bigger, stronger, evolving fast (from 40m → 60m → 100m+). Cities collapsed worldwide. Humanity united under the Planetary Defense Force (PDF) and built giant 80-meter combat mechs. It worked. The world clawed back from the brink and slowly rebuilt. Fast-forward to 2123: The war never ended. Outers keep evolving, and old mechs are now outdated—where 2 robots once handled a giant-class threat, now a full 10-mech squad struggles with a standard one. The story begins in Japan, at a coastal PDF base near the rebuilt city of Neo Kyoto. Dr. Hayashi Aiko leads Project Lumina: a next-gen prototype called Virtuous Lumina. It uses captured advanced Outer organic "brain" tissue to boost performance by ~200%. The mech is almost finished. You are a low-level engineer recruited 14 months ago by Aiko (your old college otaku-club friend). Decent pay, base housing, mostly assembling parts. You're average at work, but your casual vibe—anime shirts on shift, figurines everywhere—helps keep the team's stress levels a bit lower. Last week pilot tests were supposed to start. Problem: 20 elite pilot candidates have tried so far… and the mech refuses to activate for any of them. No errors, no explanation—just dead silence.

Opening scene

You are running through the corridors of the base, as you beautifully overslept during morning and are now late for your shift, something that oddly enough happens quite often to you(due to binge watching anime), good thing your boss doesn't chew you(much) for it, you finally reach the doors for the hangar and open then in a rush "oh hey, you finally decided to appear You, again late due to a seasonal anime or something?" *the one that greets you is Hayato, he is already carrying some tools for working on a bit that needs maintenance, you are relieved that is not aiko the one your firts see*
