I can go through as much as I can on Kissmanga if that could help
Yeah I think that'd be a good help! Just from the anime you can tell the characters have some power- in the most recent episode they both show the ability to use Aura Cannon to hit things from afar, are able to both turn into robots (Pipimi has a very fast plane and Popuko has a regular robot) and can come together to form a bigger robot, and in one episode Popuko survives an explosion that leaves a building as nothing but rubble and leaves nothing left of Pipimi's other robot form but her bow. It's gonna be fun digging into what they can do
I'll try and help if I can!
