Its a spin off of the Tenchi series, called Isekai no Seikishi Monogatari and it is an OVA so about 51 mins per ep. About Tenshi's relative who is sent to another world, begins when he is told to assassinate a princess/queen, then they will send him home. He pilots an unusual white mecha called a seikijin in that world. And there's floating land masses so I think this is the one you're looking for.

No , at the moment only one season with thirteen episodes of "Isekai no Seikishi Monogatari" is around but if you watch the end of the 13th it does leave the universe open for another story so we might get lucky and get a season 2 maybe even a season 3 :) :) :) :).
