Having cringe in a weeaboo setting is like having grimdark in a 40k game, you're not just allowed to have it: it's required.
You might want to have a very carefree attitude towards worldbuilding and let the characters and action shine and carry the show. For instance in a super robot mecha game you wouldn't try to explain too hard why only Japan is under attack by alien kaijuu and is able to produce the correct amount of teenager pilots that can give humanity a fighting chance - your brain power goes to describing the fighting and subsequent devastation.
