Kokaku no Regios

I Have Finished watching Koukaku no Regios or Chrome Shelled Regios months ago but i still wish for a second season though ....... want to see more fighting and Comedy + romance ~.~

So i'll do a rough summary because i don't remember much .......... ( sowwy :P)

So it's basically like this .............
It's the future where people have started living in chrome shelled cities called Regios which are able to move. The outsides of these cities are inhabited by filth monsters which constantly attack these cites ( i don't know why >.<) so the people living in these cities have to defend themselves................

The story is about Layfon Alseif a high school student ( i think ) who was exiled from his home "Regios" and ended up coming to ( forgot name >.< ) where he makes friends and enemies ( who some are still his friends ) and is forcefully made to join a squad led by Nina and embarks on a series of adventure and comedy =3
