This Charlotte special takes place between episodes 3-5 of the original series. The student council responds to another ability user, this time a young girl named Iori who can passively project other people's thoughts.
The plot is wholesome albeit simple. Nao wants to cheer this girl up so her and Yuu hang out with the little girl. Nao earns Iori's trust and gets her friend Honoka to spend time with her again. We get the typical bickering between Yuu and Nao plus Nao's relationship with Iori is wholesome.
The animation follows the expectations set by the original series. There are none of the crazy camera movements, it's pretty smooth, and it's inoffensive. The soundtrack returns along with the opening and ending.
If you liked the first half of Charlotte then you'll enjoy this special. For me it's pretty forgettable but falls in line with the rest of the series. It's a nice bonus episode if you want just a little more content.
