There seems to be a lot of exclusive content in the anime of Chuunibyou demo Koi ga Shitai!, such as Sanae Dekomori, Kumin Tsuyuri, and Touka Takanashi (Rikka's older sister) all being exclusive to the anime.

What major differences (how differently do the events in the anime play out in the light novels) are then in the light novel compared to the anime? Why did the production make such changes?


  • Is this really true? (Sorry - never seen the novel before) I can't imagine how the story plays out without the involvement of those "side" character.

According to this post, the Director, Tatsuya Ishihara mentions in a NewType article that:

Shinka Nibutani appeared in the novel, but Kumin Tsuyuri and Sanae Dekomori are anime original characters. The reason they were created was that there wouldn't be enough characters for a TV series. Similarly, the story has been arranged to have many new elements added.

"The amount of novel material we had was insufficient even though it was published via Kyoto Animation's KA Esuma label. In short, it feels more like an original series from our company. Because of that, we put so much effort into this series. 'Make it entertaining until the very last scene!' We put in every entertaining moment we could think of and arranged them together. The end is also different from the novels. We hope you enjoy watching it until the very end."

  • This makes sense. The manga is definitely different due to the lack of the anime characters, and it does seem to give the anime a life of its own. Thanks for (eventually) finding the answer on this one.
