The Quintessential Quintuplets

It was decided the protagonist should be quintuplets at the very beginning. When later the idea of quadruplets and sextuplets was raised, it was rejected very quickly, around 30 seconds. Haruba said it might be a reference to Super Sentai when he came up with this idea. Similar to Super Sentai, Ichika (yellow), Nino (black), Miku (blue), Yotsuba (green) and Itsuki (red) are all represented by a colour. The design of the quintuplets started from his favourite existing female characters from "some slice-of-life works only with girls", around 15 to 20 of them. The idea of adding numbers in their names was after the design was almost confirmed.[3]

The hair colour of the Nakano quintuplets are different when being coloured, which was suggested by Haruba himself, such that they are more distinguishable from each other. The hair colour of the bride in the flashforward is therefore a colour-in-between.[3]

The flashforward that Futaro will eventually marry with only one of the Nakano quintuplets was for eliminating the possibility of marrying all five of them, which would be a lazy ending. It was also decided all quintuplets would anyway have negative feelings towards Futaro from the beginning because Haruba wanted to write how their relationship improved from hate to love in the story, except Yotsuba, who has to act as Futaro's guide for the development of the story.[3]

While it is normal for harem romantic comedy manga to have sexy depiction, Haruba tried to avoid it to some extent after Vol. 1. In his opinion, showing panties which are being worn, i.e. panchira, makes characters less mysterious and then less interesting to the readers. To keep the characters interesting, the sexy scenes were intended to be ambiguous but not straightforward, leading to readers' imagination. The swimsuit appearance of the Nakanos was finally revealed in Ep. 92 as Haruba thought an episode of swimming suits should exist before finishing the story.[3]

The Quintessential Quintuplets received positive reviews, most notably for its romantic comedy and harem elements.[2] Paul Jensen of Anime News Network found the series enjoyable and rated a 4 out of 5 to the series, as he commented "The jokes are funny, the characters range from tolerable to likable, the fanservice doesn't go overboard, and there's no creepy or obnoxious plot point to spoil the party. There's nothing revolutionary about it, but it does a lot of basic things well without showing any major flaws, and that's enough to make this premiere good clean (well, clean-ish) fun."[1] Patrick Frye of Monsters And Critics noted that there was "little to no ecchi shenanigans or degrading fan service and the girls move beyond the initial stereotypes and become fleshed-out characters that create a fun dynamic with the main character, Futaro Uesugi. Audiences are tired of watching a lucky everyman stumble his way through unlikely scenarios. Instead, Futaro’s no-nonsense attitude wins the day."[36] Kyle Rogacion of Goomba Stomp praised the plot of the anime but criticized its art style and fanservice gags.[37] The series has a current score of 4.6 out of 5 stars on Crunchyroll as of November 2020.[38]
