Love, Chunibyo & Other Delusions! Rikka Version
What they share
Both films are directed by Tatsuya Ishihara, and they both carry the bittersweet, tender mood tags, and they sit in Animation / Comedy territory.

What Love, Chunibyo & Other Delusions! Rikka Version is
Apparently romance can be found in delusions. Rikka's perspective retells the first season with new elements. It somehow ties everything together.
