You get the impression Rikka's chuunibyou is heavily influenced by anime and games. In reality it's also influenced by something else. What that is remains a secret for now. (smiles)

Regarding the origin of Rikka's chuunibyou

Spoiler for responding to the spoiler above:

That comment, added to some of the dialog in episode 1, makes me think Rikka was heavily influenced by DFM, be it either when visiting her sister, or through the internet. It is a bit contradictory though that she was already full delusional when she met Dekomori two years ago. The timelines seem a bit unbelievable in that case.
