Fridge: The Familiar of Zero
- Technically Louise comes very close to being a Yandere in the novels. In one scene, seeing Saito with another girl upsets her so much she hits him with a explosion spell which apparently comes very close to killing him. Apparently, he couldn't even move afterwards.
- Actually, just Louise and Saito's relationship in general if you think too hard about it. I mean, in the anime at least, it's implied that Saito being whipped is a daily event, and if you take into account that he still does her laundry and sets out her clothes, and gets whipped if he does complain about it, Saito looks kinda like a slave.
