Calibarn is a neat design. I still have mixed feelings about this show, I love the mobile suits and the character designs but the world-building has been lacking. They've barely explained what Permet is even though it's central to the plot. Why would flying a suit without permet be like driving a car blind? Nobody elaborates, and for some reason Chuchu is totally fine with it which completely undercuts its importance. Is she going to be just fine when her demi barding deplots with that antique cockpit?
