- Fan Nickname: Kaoruko is called "Houbunsha'snote biggest crybaby" among Chinese viewers, because of the frequency she cries in the series; some statistics showed she cried a total of 40 times in 2016 and 2017 combined. That's more than 1.5 times per chapter.
- Side-Story Bonus Art: when the US state of Missouri was the only state where Comic Girls was the most watched show on Crunchyroll, Hanzawa created a Thank you picture, with Kaos-chan bobbling a plate of barbequed ribs in front of the St. Louis arch.
- Talking to Himself: Hikaru Akao voices for Kaoruko and her cat Nyaos.
