Gonna call bullshit on Greengoat's part of the collab:

 In order to make Hayami a magnet, she'd have to be a good electrical conductor (assuming she is since she uses electricity as a power) and sent a current in a spiral around her body, which is far out of her range of control. Even then, she wouldn't just repel the metal: the other "pole" of her magnetized self would be attracted to it and flip her over, throwing her harder against it. Have you ever held a strong magnet against a fridge on the repelling side, then let go? It flips to the other side and sticks to the fridge.
