for campione the best would be to read the light novel translated by baka-tsuki the anime is nowhere near as good and lacking alot.
I agree. And if he wants the part about them disliking each other first he could start with volume 3 since it's the "prequel" of the story, obviously he wouldn't understand something, but I think it's still pretty understandable even reading it in chronological order. In the anime in fact it's episode 1, but the anime is really a mess, also being an Italian I can assure they lost many important cool hints especially about Liliana that the author dropped in the novel.
