They are both pretty dark compared to the average anime in their main genres (school and fantasy), both series are also featuring a bizarre love relationship in where one is a predator that tries to repress their power or otherwise they can cause a catastrophe and harm their loved ones and the other is an ex-potential suicide that had really hard lives. Both anime gave me a sensation in where unavoidably one will destroy the other.
