* EarWorm: The opening and closing credits.
* {{Fanon}}: It's easy to think of Nagase as KC's [[VideoGame/Persona3 Junpei]] (it helps that they share the name, Iori).
* InternetBackdraft: The incident with Creator/MitsuhiroIchiki quickly became a reviled topic, and one that both this project and many of the voice actors involved will [[NeverLiveItDown be remembered for]]. Because of the treatment of Ichiki (namely, that he was called in to do an audition for a character that didn't even exist, and not only ''didn't'' get the part, but was relegated to a PR manager who got humiliated and electrocuted in one incident), otaku were furious and planned to boycott the anime. See [[https://www.reddit.com/r/anime/comments/zm4yx/a_summary_of_the_kokoro_connect_prank_incident/ here]] for all of the relevant information.
* JerkassWoobie: Inaba.
* MagnificentBastard: Heartseed
* {{Moe}}: [[spoiler:4 year old Inaba]] from episode 11.
* {{Wangst}}: Inaba's confession about her trust issues in episode 4 is supposed to be genuine, but comes off like something an emo teenager would write in their diary.
** Arguably the point of the entire scene; considering how little the rest of the cast seemed to care about her confession, the show made it seem like she was worrying over something pointless.
* TheWoobie: Iori
