What does the grimoires do?

So what exactly are Grimoire of apotheosis and Evolved Grimoire for? I've seen a few people write that I should wait until a later event to get them but still want to know why. Is there no use for them at the moment?

From what I recall reading here, they're for the last Limit Break on SSR and SR Kamihimes. It may take several of them for a single hime though, so it's not advisable to pick them up right now unless you're literally about to use them.
