Royal Space Force: The Wings of Honnêamise
The plot is simplistic, but the visuals are just great, with a lot of detail. They really created a new alternative version of Earth, different from anything I ever watched, with roots in steampunk and more modern stuff.
That ONE scene comes out of nowhere and gets resolved by not mentioning any further. It’s just a lame excuse for “fanservice” target at creeps, but it can be overlooked.
