Introduction: One Guy, One Hundred Girlfriends… and A Deadline to Stay Together
Imagine confessing to 100 girls… and getting rejected by every single one of them.
That’s the life of Rentarō Aijō, the male protagonist of The 100 Girlfriends Who Really, Really, Really, Really, Really Love You (often shortened to 100 Kanojou or “Hyakkano”). The setup is wild, absurd, and perfectly built for comedy—but beneath it lies a surprisingly sweet core about connection, devotion, commitment, and sheer absurdity in love.
In October 2025 the franchise dropped the bombshell: Season 3 coming in 2026. With Season 1 airing in late 2023 and Season 2 running from Jan–Mar 2025, the stage is set for a new chapter of high-school harem romance gone gloriously over the top.
But what makes this show tick? Why are fans so excited? What can we expect from Season 3? And how did this wild premise even start? Let’s dive in.
1. The Origin Story: Manga to Anime and the Jump to Harem Legend
Manga Beginning
The journey began with a manga written by Rikito Nakamura and illustrated by Yukiko Nozawa, serialized in Weekly Young Jump (Shūeisha) from December 2019. As of September 2025, the series has 23 tankōbon volumes, with Volume 24 planned for December 2025.
Anime Adaptation
The anime adaptation by Bibury Animation Studios was announced in March 2023, with the first season airing October 8–December 24, 2023 (12 episodes). Season 2 followed January 12–March 30, 2025, also 12 episodes.
What This Means
This is more than “just a harem anime.” With this pace and volume of content, the anime has carved out a massive space for itself—so much so that the announcement of Season 3 in 2026 feels like a Big Deal.
2. The Premise: Love, Deadlines & Cosmic Soulmates
Here’s the wild premise in a nutshell:
Rentarō Aijō has confessed to 100 girls—and been rejected each time. Desperate for change, he prays at a shrine. A “God of Love” shows up and says: his rejections happened because of a mistake—he is destined to date 100 soulmates. But there’s a catch: if he fails to return the feelings of each girlfriend, she’ll suffer fatal misfortune.
So yes, it’s romance… but with cosmic stakes. It’s harem… but with bizarre devotion. And comedy? Oh yes—the chaos never stops.
3. Why It Works: Comedy, Heart, and Harem Done Differently
Massive Harem Scale
Most harem shows feature 3-10 girls. This one? 100. That scale alone makes every interaction feel amplified: each confession, each date, each “I love you so much” moment becomes a spectacle.
Emotional stakes meet goofball humor
Despite the absurdity, the show manages to make these 100 girls feel real. They each have quirks, personalities, hopes, jealousy, and fears. Rentarō’s challenge isn’t just to keep up—it’s to maintain genuine relationships in impossible circumstances.
Self-Awareness and parody
The anime doesn’t just play the harem trope—it explodes it. It’s aware of its own ridiculousness, and uses that to create comedic beats while still delivering emotional sincerity.

5. What We Know About Season 3 (2026) & What to Expect
Announcement & Timing
According to multiple sources, Season 3 was officially announced in October 2025 to premiere in 2026.
New Girlfriends Revealed
The announcement trailer revealed two new girlfriends: Chiyo Iin and Naddy. These additions signal that the story will continue expanding the harem, raising the stakes further.
Source Material Depth
With 23 volumes published by 2025 and a 24th arriving in December, the manga has plenty of story left to adapt. The anime only covered a fraction. That means Season 3 could dive deeper into character back-stories, conflicts, and maybe even some major plot revelations.
Expectations & Speculation
- More girls, more stories: The number of girlfriends will grow; each new one brings new dynamics.
- Higher emotional stakes: As Rentarō’s relationships multiply, so will the conflicts—jealousy, scheduling chaos, feelings of inadequacy.
- Deeper themes: Amid the comedy will likely come moments of genuine reflection—identity, love’s meaning, and personal growth.
- Production value: With 2026 release, animation quality and special episodes may get upgrades, supporting the hype.
6. Themes & Why It Resonates
A. Love Doesn’t Count—It Connects
Though there are 100 girlfriends, the core theme revolves around connection—not numbers. Rentarō is challenged not just to collect girlfriends, but to love each one genuinely.
“It’s not about who’s first or last—it’s about being there when it matters.”
B. Commitment in Absurdity
When the premise includes “fail and they’ll die,” you know the stakes are literal—but the series plays this with tongue-in-cheek humor. It’s marriage commitment logic applied to teenage harem scenarios, and the absurdity highlights the difficulty of real emotional commitment.
C. Harem Reimagined
Rather than fracture into “girl fights for guy” tropes, the show fosters friendship, cooperation, and heartfelt interactions among a huge cast. The harem becomes a community, not just a competition.
D. Humor as Escape and Reflection
The show is ludicrous, yes—but that allows it to reflect real insecurities, fears, and teen awkwardness in exaggerated form. Crying over a date schedule? That’s pretty real.

Conclusion: One Story, Many Hearts
The 100 Girlfriends Who Really, Really, Really, Really, Really Love You isn’t just a harem comedy—it’s a celebration of ridiculously abundant love, commitment under pressure, and the chaos that comes when you aim to love everyone.
With Season 3 confirmed for 2026, the chaos is far from over—it’s just getting started. Rentarō’s journey to please 100 girlfriends ends up showing us how love, in all its forms, can be absurd and beautiful at the same time.
“If loving one girl is hard… try loving a hundred.”
And in that impossible challenge, there lies the heart of something unforgettable.
