Top 20 Addictive Anime Characters Ranking by Spacomic: Kamishiro Rui Takes the Crown
As 2025 draws to a close, one of the hottest topics among anime fans is undoubtedly—who is that "swamp-type character" that, once you fall in love with them, you can never turn back?
The term "swamp" (沼), in Japanese slang, refers to a state like a quagmire, where once you step in, you sink deeper and deeper, unable to extricate yourself. Spacomic recently released a highly anticipated ranking, surveying the characters fans find most "immersively charming." This list not only covers classic long-running hits but also includes popular new works that have risen in recent years.
Below, we take an in-depth look at this list to see which characters have fans willingly dedicating their souls and wallets.
What is a Swamp-Type Character? Why Are Fans So Enthralled?
Before diving into the rankings, let's define "swamp-type character." These characters aren't necessarily the absolute main protagonists but often possess the following traits:
- Extremely strong gap moe
- A heavy, tragic past
- An elusive sense of mystery
They aren't just handsome; they possess a magic that makes people want to "learn more about them" or "protect them."
Swamp-Type Character Top 3: Soul-Stirring Figures That Make You Sink Deep
The top three on this list perfectly showcase different types of "swamp" attributes.
No. 1: Kamishiro Rui
From: Project SEKAI COLORFUL STAGE! feat. Hatsune Miku
Kamishiro Rui from the popular rhythm game Project SEKAI claims the throne. As the producer for "Wonderlands×Showtime," beneath his image of a mad inventor with a playful smile and wild ideas lies deep care for his companions and a past marked by loneliness. This coexistence of genius-level madness and delicate tenderness is the quintessential "swamp-type" trait.
No. 2: Japan / Honda Kiku
From: Hetalia: Axis Powers
Japan from the classic series Hetalia takes second place. As a personification of a nation, his character—cautious, polite, yet a closeted otaku—has, over the years, seen his charm not diminish but grow. That "steady sense of security" combined with occasional moments of natural airheadedness is an eternal home in the hearts of many fans.
No. 3: Dazai Osamu
From: Bungo Stray Dogs
When it comes to characters that make you sink deep, how can we not mention Dazai Osamu? Whether as the frivolous senior at the Armed Detective Agency or the cold, efficient executive during his Port Mafia days, his nihilistic aura—always talking about suicide yet perceiving everything—draws readers in like a black hole.
