by As 2026 officially begins, expectations are already high for what many are calling a bumper year for anime. With dozens of high-profile sequels and new titles scheduled to air, fans are eager to see which series will dominate conversations this year.
But before looking ahead, it’s worth taking a step back. At the end of December 2025, Bushiroad’s group analysis organization released the results of a large-scale survey analyzing 270 anime series that aired in 2025. The data not only highlighted the most popular shows of the year, but also revealed something just as interesting:
the “dark horse” anime that quietly gained momentum and dramatically exceeded expectations.
What Is the “Dark Horse Award”?
The survey was compiled using objective online data, rather than subjective rankings alone. Two key metrics were used:
- Trend Score – based on Google search volume
- Fan Score – based on activity and engagement on X (formerly Twitter)
In addition to the Annual Grand Prix, which recognizes anime with the highest overall popularity during their broadcast period, the study also presented a Dark Horse Award. This award focused on growth rate, measuring how much a title’s popularity increased after its debut.
In today’s anime landscape where nearly 70 new titles air each season—this metric has become increasingly important. A strong opening episode alone is no longer enough; sustained growth and word-of-mouth buzz now play a major role in a series’ success.
Dark Horse Champion: Galaxy Express Milky☆Subway
The standout winner of the Dark Horse Award in both the Trend Score and Fan Score categories was Galaxy Express Milky☆Subway.
Eye-Opening Growth Numbers
- Trend Score growth: 20.0×
- Fan Score growth: 31.2×
These figures represent one of the most dramatic popularity increases recorded in the survey.
Interestingly, the series had a very low ranking in its first broadcast week, placing near the bottom among the 270 titles analyzed. However, as weeks passed, online discussion steadily increased. By the end of the year, the anime had climbed to:
- 7th place in the annual Trend Score rankings
- 4th place in the Fan Score rankings
This sharp rise demonstrates how powerful long-term word of mouth can be, especially when a show resonates with viewers over time rather than relying on instant hype.
Annual Grand Prix Winner: Mobile Suit Gundam GQuuuuuX
While Galaxy Express Milky☆Subway dominated the growth rankings, the Annual Grand Prix—awarded to the anime with the highest overall popularity during its airing went to Mobile Suit Gundam GQuuuuuX.
As part of the long-running Gundam franchise, the series benefited from:
- A strong existing fanbase
- High initial visibility
- Continuous online engagement throughout its broadcast
This contrast between Gundam and Milky☆Subway highlights an important distinction: established franchises dominate total volume, while original or niche titles can still win through growth and momentum.
Other Notable Dark Horse Performers (Trend Score Growth)
Several other anime showed impressive increases in Trend Score, indicating rising public interest:
- Everyday Host – 4.5×
- The Legend of Hei – 4.5×
- Nohara Hiroshi’s Lunchtime Style – 4.4×
Why Did These Shows Gain Momentum?
- Everyday Host benefited from its free availability on YouTube and short-format episodes, making it easy for fans to recommend casually. This significantly lowered the barrier for new viewers.
- The Legend of Hei, a Chinese-produced animation, gained renewed attention thanks to the release of a sequel movie in October, which coincided with its TV broadcast.
- Nohara Hiroshi’s Lunchtime Style found strong resonance on Niconico Douga, where its humor and relatability matched the platform’s audience culture.
Fan Score Standouts: Passionate Communities Drive Growth
In terms of Fan Score growth, which reflects posting activity and enthusiasm, two titles stood out:
- A Wild Last Boss Appeared – 8.9×
- The Dark History of a Reincarnated Villainess – 8.0×
These results suggest that even if a series doesn’t dominate mainstream searches, a highly engaged fanbase can significantly amplify its presence online.
Key Insight from the Analysis Team
According to the organization that conducted the research:
“Buzz from the first episode isn’t everything. What matters is whether the story development and themes align with the times.”
This insight reflects a growing shift in anime consumption. Viewers are increasingly willing to give shows time—especially when the themes feel relevant, emotionally engaging, or easily shareable.
What This Means for Anime in 2026
With nearly 70 anime titles released every season, competition for attention is fiercer than ever. As 2026 unfolds, creators and production committees are expected to focus more on:
- Long-term audience engagement
- Accessibility through streaming and social platforms
- Encouraging organic fan-driven promotion
The success of 2025’s dark horse titles shows that quality, timing, and community buzz can outweigh flashy debuts.
Final Thoughts: Expect the Unexpected in 2026
While major franchises will undoubtedly dominate headlines in 2026, last year’s data reminds us not to underestimate quieter releases. The next breakout hit may not arrive with massive hype but could grow steadily into a fan favorite.
If 2025 taught us anything, it’s this:
the true stars of anime are often discovered after the opening credits fade.
