"The closest answer to that which I can find is 'hunting game'. The sentience of Hollows has never come up as an issue before, mostly because they've never made much use of that sentience. But something changed, hasn't it?" Koutarou replies as he peruses the parchment. "I don't doubt that someone, somewhere, has asked himself something that's essentially closer to what the Espada proposed - if Hollows are a product of spiritual nature going about its business, why do we fight them?

Although that's a moot point now, I suppose. Whether we started hunting Hollows out of sport or duty, the fact remains that the hatred between Shinigami and Hollow runs deep."
