A bunch of kids live in a mobile academy in a world where the outside air is toxic and giant bugs roam the landscape. Our main character Layfon Alseif is extra strong but has issues using that power. He also has lots of girls only too willing to jump his bones. Chrome-Shelled Regios is basically a cross between Nausicaa of the Valley of the Wind and Gundam Seed, without the mecha.
It’s one season, 24 episodes long and divided into a number of arcs, but there’s no real story. It’s just episode after episode of Layfon and his captain Nina taking turns angsting over inconsequential crap.
Layfon: I don’t wanna fight.
Nina: Get over yourself.
Nina: I’m too weak.
Layfon: Snap out of it.
Layfon: I don’t wanna fight.
etc, etc, etc.
Intersperse this with battles against bugs and men and add a number of side characters who don’t do much or mean much and you’ve got yourself a series. It does seem like *eventually* they’ll figure out a way to purify the skies outside and take out all the bugs and reclaim their world, but at the glacial pace the series moves, this probably won’t happen till Kenshiro comes around in 20XX.
It’s still fun enough that I watched the whole thing, but if they made a second season it would still be more angst angst-action-angst-action-angst-lame attempt at comedy-angst stuff, so I’ll just wait for the whole light novel series to end and read the ending with my grandchildren.
Update: Huh. The light novel series did end, in 2013. Much sooner than I’d expected. I’ll have to find the time to read the whole thing from start to finish, because apparently the anime left out a lot of things. I was rooting for Layfon to get together with… never mind, I’ll save the spoilers for when I do read the whole thing. Look forward to the update, in 20XX.
