I did it, I rewatched another trashy anime and actually paid attention and this time it is Diabolik Lovers. I think I might eventually need to get my hands on the light novel, the manga or the games to get some of the answers. Since I do not have access to these at the moment and have not looked at them, I am unsure if the anime was just adapted assuming these key points were already known, or if the explanations did not make the cut due to time constraints. Either way, some points left me confused.
Shoujo anime is great for those easy-going feel-good anime on the whole. However, due to their pure nature of focusing on relationship building between characters they often hit the feels and break you down before healing you with all their fluff. But what does Shoujo mean?
