User Recommendations for Pandora Hearts

The fate of the main heroines are similar, they both depend on the youth to unleash their power, they share a passion for one type of food and also they are not fully human

Heroins are similar. Stong willed and stubborn with a soft side. There is light comedy in both. The story and imagery are mysterious and dark. Chains are similar to Rinne - they eat people. One faction must stop another (Flame Haze vs. Guze - Pandora vs. Baskerville) There is a grip of action in both animes. If you liked SnS then you'll like Pandora Hearts.

Both series deal with beings from an alternate realm they don't want to be in forming contracts with humans. The difference is that all beings in Pandora Hearts are beings called Chains who want to escape and humans who want to change the past, whereas in Shakugan no Shana, it is about Denizens wanting to eat the Power of Existence of humans and stronger Denizens known as Lords contracting with Humans to grant them power to stop the Denizens.
