Before this post gets used for shitposting or overreactions I want to remind you that Zeztz is still a kodomo show airing a kodomo time slot so as much of an adult show they want to be they'll always need to consider the kids in some form.
Basically Zeztz is the same situation as Build and King-Ohger which tried to appeal to adults, only that this time rather than the reasoning being to try to get older fans back and adults that aren't engaging with this franchise but to get western adults, since the western children fanbase is basically non-existent.
