The 100 Girlfriends Season 4 Release Date and Predictions

100 Girlfriends Who Really, Really, Really, Really, REALLY Love You Season 3 (Kimi no Koto ga Daidaidaidaidaisuki na 100-nin no Kanojo) is one episode away from being done, and honestly, most of the conversation has already jumped ahead to Season 4. No official announcement yet, but that hasn't stopped anyone from guessing.

When Season 4 Might Actually Show Up

Here's the thing working in everyone's favor. This show has been coming back fast. Season 2 took over a year to come out, and Season 3 arrived over a year after that. Bibury Animation Studios clearly has a rhythm going, and shows that keep this kind of turnaround usually aren't sitting on the shelf for long.

If that pattern holds, a renewal announcement could come within six months or so of the finale, with the season itself landing sometime the following year. Some people think it might already be quietly in production given how quickly Seasons 2 and 3 came out. That's guesswork, but it's not unreasonable guesswork.

Where Season 3 Has Taken Things

Season 3 has been doing what this show does best, which is throwing absurd comedy at you for twenty minutes and then hitting you with something unexpectedly sincere. It opened by breaking the fourth wall, added several new girlfriends to the lineup, and kept finding room for the older cast members in between.

The second half has been absolutely chaotic. Recent episodes slowed down to focus on existing relationships instead of racing toward the next introduction, and a lot of fans have said those unhinged episodes ended up being their favorites.

Episode 12 Closes Out the Season

1. Episode 12 airs September 20, 2026 on Crunchyroll
2. Same weekly slot as always at 7 a.m. PT / 10 a.m. ET, with subs and dub

The series has ended every season with a more serious, character driven arc, and Season 3 is clearly breaking molds. The finale should wrap up the emotional storyline the last episode set up. Expect the usual mix though. Even the heavier episodes of this show find room for jokes, so a completely straight-faced finale would be off brand.

What Season 4 Could Pull from the Manga

There's no shortage of material left. Based on where the manga is now, Season 4 would likely cover:

1. Several new girlfriends the anime hasn't gotten to yet
2. Longer gaps between introductions, since the manga slows down considerably after girlfriend 21
3. More chapters focused on the existing cast and their dynamics with each other
4. Bigger group storylines, including a sports tournament arc that would make a solid finale

That pacing shift is the interesting part. The manga stops introducing characters back-to-back after a certain point, which means Season 4 might naturally feel less rushed than Season 3 did, whether the studio plans it that way or not. And if you missed it, the Season 3 trailer is a good reminder of what this show is like when it's firing on all cylinders.

The Pacing Debate Everyone Is Having

Not everyone's thrilled with how Season 3 handled the source material. Around 14 chapters got skipped this season, including several character focused ones that longtime readers were hoping to see animated. The worry is that if Season 4 keeps the same speed, even more gets cut.

The counterargument is pretty reasonable too. Adaptations trim things. Plenty of well-loved adaptations across film and TV have dropped material and still worked because they kept the spirit of the original intact. Some fans have suggested the studio could bring on a second studio or outsource parts of production if it wants longer seasons, which is what other big series do when the workload grows.

Why Three Seasons Is Already a Big Deal

Worth stepping back for a second. This anime is on its third season with strong streaming numbers, a growing cast, and merchandise to go with it. That's a genuinely good position to be in, and it's the strongest argument for Season 4 happening. The show even holds a Guinness World Record now, for the longest monologue in a Japanese animation, earned by Rentaro's 7,453-character love speech at the end of Season 2. Voice actor Wataru Kato, who voiced that entire speech, described the experience on the Guinness World Records official website, saying:

"When you actually voice that volume of text, you feel moved by how much someone can think about others." - Wataru Kato, Japanese VA of Rentaro

Voice acting costs get brought up as a concern given how many characters there are, but the show already brought in big names this season, so the budget clearly isn't scraping bottom.

Keep an Eye on September 20

The finale is the immediate thing to watch. Season enders are often when studios drop announcements, so there's a decent chance a Season 4 teaser or production notice shows up alongside it. Even Travis Mullenix, who voices Rentaro in the English dub, was buzzing about the show's momentum after the Guinness news broke, publicly saying:

"Seriously that is absolutely wild! Ecstatic that I did something truly historic." - Travis Mullenix, English VA of Rentaro

Until then, the manga is the move for anyone who can't wait.
