Alright I appreciate the feedback thus far. I'll go over what you guys have suggested, and consider what my best options are on the matter, and how I intend to, if at all, make the roleplay happen. Regarding the monster situation in Evangelion there is nothing but big monsters, and in Franxx there tends to be a mix of smaller monsters, or bigger ones that turn into smaller ones (sometimes). The show itself isn't that great a lot of people like it for shipping purposes but I feel like it would work well as a roleplay which is why I'm considering making it in the first place. The whole concept of being so dependent on a partner yet not excluding one side of the relationship as one sided (I.E Fate/Zero for example where the master lets his servant do whatever he, or she wants in fights but controls/anchors them). I don't know people on this site very well, and there seems to be a vocal few that dislike me for my frankly draconian style gm'ing.

 I don't think I would make good in a custom setting like Broken suggests because then I would need to make whole new lore, and Evangelion's inspiration would simply be the city defense style where as Franxx does mobile cities that go from one place to another. I prefer a more grounded roleplay as if we're constantly setting swapping from one location to another I need to make a note of what the environment is like every time we do a battle, and I'm already bad at settings as it is.
