The 100 Girlfriends Season 4 Release Date, Renewal Status, and Rumors: What We Know So Far
There are plenty of harem anime where the protagonist struggles to choose between two or three girls. Then there is The 100 Girlfriends Who Really, Really, Really, Really, Really Love You, a series that looked at the entire genre, laughed at its rules, and basically said, “Why choose at all?”
That ridiculous premise is exactly why I think the question of The 100 Girlfriends Season 4 is so interesting. After three seasons of increasingly chaotic romance, absurd comedy, and a growing Rentaro Family, fans are naturally wondering whether Bibury Animation Studios will give us another round.
As of August 2026, Season 4 has not received an official renewal announcement. That is obviously disappointing if you’re already impatient to meet the next batch of soulmates, but I don’t think fans should panic. If anything, the series has built a surprisingly strong case for continuing.
And honestly? I would be shocked if this story ended here.
The 100 Girlfriends Season 4 Renewal Status
The most important thing to understand is that there is currently a difference between “not officially announced” and “not happening.”
Those are very different things in anime.
Production committees don’t always announce another season immediately. They have to look at streaming performance, disc and merchandise sales, manga circulation, licensing, and the overall commercial value of keeping a franchise alive.
For a show like The 100 Girlfriends, there is another factor that matters enormously: the manga is nowhere near finished.
That means the production team isn’t trying to squeeze the final remaining material out of a completed story. There is still an enormous amount of ridiculous Rentaro content waiting to be animated.
From a fan’s perspective, that is probably the biggest reason to stay optimistic.
When Could The 100 Girlfriends Season 4 Release?
This is where things get much more speculative.
If Season 4 receives the green light, I wouldn’t expect it to arrive immediately. Anime production takes time, and The 100 Girlfriends is becoming more complicated with every season.
Think about what the staff actually has to deal with now. The cast keeps getting bigger, group scenes involve more characters, comedy depends heavily on timing, and every new girlfriend needs her own visual identity, personality, voice performance, and memorable introduction.
This isn’t an anime where you can quietly put one protagonist and one heroine in a room for twenty minutes.
Rentaro’s schedule is basically a production nightmare.
Looking at the gaps between previous seasons, a release in 2027 or 2028 would be a reasonable prediction if Season 4 is confirmed. I personally wouldn’t mind waiting longer if it means getting a polished adaptation rather than watching the animation quality collapse because the studio was forced to rush.
For me, quality matters more than speed with this particular series.
The comedy is so dependent on exaggerated expressions, body language, frantic reactions, and rapid-fire interactions that mediocre animation could seriously damage the experience.
| Factor | Season 4 Outlook |
|---|---|
| Official Renewal | Not announced as of August 2026 |
| Manga Material | Extremely healthy |
| Franchise Popularity | Strong and highly visible |
| Production Difficulty | Increasing with the expanding cast |
| Likely Release Window | Potentially 2027–2028 if renewed |
The Manga Has More Than Enough Story
This is probably the easiest part of the Season 4 discussion.
The manga is not running out of material.
Written by Rikito Nakamura and illustrated by Yukiko Nozawa, The 100 Girlfriends has continued building its absurd romantic universe since 2019. The anime has only adapted a portion of the available story, meaning there is plenty of material for future seasons.
And this is where I think anime-only fans don’t fully appreciate what is waiting for them.
The series becomes increasingly unhinged.
That’s not necessarily a criticism. In fact, it’s one of the reasons I love it.
The manga doesn’t suddenly decide that it needs to become a conventional romance. Instead, it keeps asking how far the premise can be pushed while still making Rentaro’s relationships feel surprisingly sincere.
There are characters with bizarre gimmicks, outrageous personalities, ridiculous situations, and increasingly complicated interactions between members of the Rentaro Family.
And somehow, underneath all the insanity, the series continues to sell its central idea: Rentaro genuinely cares about every girl.
That is what separates this franchise from so many traditional harem stories.
Why Rentaro Is Such a Good Harem Protagonist
I have to give Rentaro credit here.
When The 100 Girlfriends first appeared, I expected another exaggerated harem protagonist surrounded by girls who would spend half the season waiting for him to realize that they liked him.
Instead, we got Rentaro.
He doesn’t hesitate.
He doesn’t spend ten episodes wondering which girl he should choose.
He doesn’t create endless misunderstandings because he refuses to communicate.
The guy basically looks at the impossible situation he has been handed and decides:
“Fine. I will love all of them.”
And then he actually tries.
That’s the secret sauce of the series.
The joke isn’t simply that Rentaro has an absurd number of girlfriends. The joke is that he takes his responsibility toward them completely seriously.
That creates a weirdly wholesome dynamic. Instead of constant “waifu wars,” the audience can enjoy the different personalities without needing to argue that one character deserves Rentaro more than another.
As a fan, I find that refreshing.
The Real Reason Season 4 Feels Inevitable
There is a simple question I always ask when judging whether an anime deserves another season:
Is there still a reason for people to care?
With The 100 Girlfriends, the answer is clearly yes.
The franchise has several things working in its favor.
- A huge amount of manga material remains available for adaptation.
- The premise is extremely recognizable, which gives the anime a strong identity.
- The growing cast creates constant merchandise opportunities.
- International streaming keeps the series visible outside Japan.
- The fanbase is unusually enthusiastic about discussing future girlfriends and predicting voice casting.
The last point shouldn’t be underestimated.
Go onto anime communities and you will find fans discussing future characters almost as enthusiastically as they discuss the current cast. That’s a good sign for a franchise. People aren’t simply watching episodes and moving on; they’re looking ahead.
And that is exactly the kind of audience a production committee wants.
What Could Season 4 Adapt?
Obviously, I don’t want to turn this article into a giant manga spoiler dump.
But if Season 4 happens, fans can expect the same formula that made the previous seasons work: new soulmates, increasingly ridiculous situations, larger family interactions, and surprisingly sincere emotional moments.
One thing I particularly enjoy about The 100 Girlfriends is that the new girls don’t simply replace the old ones.
That’s an easy trap for a series with such a huge cast. You introduce a new character, give her a few episodes, and then she disappears into the background because the next heroine has arrived.
The 100 Girlfriends generally tries to avoid that.
The older members of the Rentaro Family remain part of the chaos, which means future seasons can create combinations between characters that fans haven’t seen before.
And that’s potentially where Season 4 could become even funnier.
With every new addition, the number of possible character interactions grows exponentially.
Rentaro isn’t just collecting girlfriends anymore. He’s accidentally creating an entire comedy ensemble.
My Biggest Hope for Season 4
If I could ask the production team for one thing, it would be simple:
Don’t rush it.
I would rather wait until 2028 for a genuinely strong Season 4 than get a rushed continuation simply because the committee wants to maintain a yearly schedule.
The series deserves animation that can keep up with its comedy.
Some scenes need absurd facial expressions. Others need fast choreography, exaggerated reactions, or a dozen characters simultaneously losing their minds.
This is one of those anime where production quality isn’t just about making pretty screenshots. Timing is part of the comedy.
And when the timing works, The 100 Girlfriends can be absolutely hilarious.
So, Will There Be a Season 4?
My answer?
I think there is a very good chance.
That isn’t the same as saying Season 4 has been officially confirmed. It hasn’t, at least as of August 2026.
But the ingredients are there.
The manga has plenty of material. The franchise remains popular. The concept is still distinctive. The fanbase is loud. The cast keeps expanding. And most importantly, there is still a lot of story that fans desperately want to see animated.
Personally, I don’t think The 100 Girlfriends has reached the point where it feels like the story has run out of steam. Quite the opposite.
The whole appeal of this anime is watching an impossible premise become somehow even more impossible every time a new character joins.
So yes, I’m keeping my fingers crossed for The 100 Girlfriends Season 4.
And when the announcement eventually arrives, I suspect the reaction from the fanbase won’t be particularly complicated.
It will probably just be thousands of people collectively screaming:
“RENTARO IS BACK!”
Until then, the manga remains the best place for impatient fans to continue the story, while anime-only viewers can sit back and wonder just how ridiculous the next season could possibly become.
Knowing this series, the answer is probably:
Much, much more ridiculous than we expect.
Final Rating From a Fan’s Perspective
If I had to rate the chances of Season 4 right now, I’d put my personal optimism at 8.5/10.
Not because an official announcement has already happened, but because the fundamentals of the franchise are simply too strong to ignore.
The bigger question isn’t whether there is enough material.
There absolutely is.
The real question is when the production committee decides the timing is right.
And honestly, I’m perfectly happy to wait if it means the next chapter of Rentaro’s completely insane love life gets the adaptation it deserves.
