Oh lordie...Takagi-san, Takagi-san, Takagi-san. Once is just about enough, but two's a company and three's a crowd...or in this case: 3rd time's the charm.
The correct way to sum the entire series which started out the greatness of mangaka Souichirou Yamamoto's manga can be described like this:
- Season 1 was the base foundation, an introduction / prologue if you will, into the couple that is the teasing master Takagi-san and her "boyfriend" Nishikata, along with the Ashita wa Doyoubi girls Mina, Sanae and Yukari as a side story;
- Season 2 is more of the same, but with hints of romantic progression between the two leads, and last but not least;
- Season 3 is the pinnacle and epilogue of the parent series with character development being the central focus thus far, adding their other classmates that we've already known but being couples now (Mano X Nagai, Hojo X Hamaguchi). And for diehard Takagi fans (like myself), the VERY FIRST introduction of Chi, and I'm not gonna spoil this to anime-onlies since it plays a huge part in this mangaka's world of Takagi-san as a whole.
Not to mention that literally 2022 is Souichirou Yamamoto's year of getting 3 simultaneous adaptations in a row, 3! Consisting of this wrapped-up Season 3, Spring's Kunoichi Tsubaki no Mune no Uchi a.k.a In the Heart of Kunoichi Tsubaki by CloverWorks, and Summer's Soredemo Ayumu wa Yosete Kuru a.k.a When Will Ayumu Make His Move? by Silver Link. Add in the movie/film that was just announced hastily for June, and I can tell you that this is a lot to take in, and Souichirou Yamamoto is really raking it rich with his works that are adored by many. All we're left is WHEN will we eventually get the (Moto) spin-off adapted, now that will be the greatest thing ever.
As for Season 3, TL;DR, if you've watched both Seasons 1 and 2, expect the very same thing here, but with the romance stakes pushed up higher as both Takagi and Nishikata get baby steps closer to each other...well, that's if the awfully dense Nishikata ever will get a hint. More original stories that aren't from the manga are added in for more romantic spice, and add in the oh-so-remembered Yuiko Oohara and Rie Takahashi differential songs line-up of an OST, and all in all, this is the Takagi-san that we all know and love since its inception.
Takagi-san has always been great since Day 1, who can really fault it? No one it seems.
