Takopi’s Original Sin has officially cemented its place in anime history after claiming the top spot in the Summer 2025 anime weekly rankings for the fifth consecutive week, completing an undefeated streak from its premiere to finale. This remarkable achievement marks only the second time in ranking history that an anime has won every single weekly poll during its airing, with the first being The Dangers in My Heart Season 2’s flawless 12-week run in Winter 2024.
Produced by ENISHIYA and based on Taizan 5’s emotionally charged manga, Takopi’s Original Sin began streaming on June 28 and concluded on August 1 with its sixth episode. Each week brought in a wave of audience support, consistently placing the series ahead of strong competitors like DAN DA DAN Season 2, The Fragrant Flower Blooms with Dignity, and The Summer Hikaru Died. Even in weeks where voter turnout fluctuated, Takopi’s grip on the number one spot never loosened, a testament to its deep emotional impact and storytelling prowess.
Directed and written by Shinya Iino, with character designs by Keita Nagahara, the anime brought Taizan 5’s short but powerful manga to life with striking animation and heartfelt performances. The story follows Takopi, an adorable alien with a mission to spread happiness, whose attempts to help a troubled young girl named Shizuka spiral into a complex tale of time travel, grief, and sacrifice. Its blend of emotional depth and unexpected twists struck a chord with viewers, fueling passionate discussions online and keeping it in the public spotlight for its entire run.
The manga, originally serialized on Shueisha’s Shonen Jump+ from December 2021 to March 2022, was quickly recognized for its unique mix of innocence and tragedy. With only two compiled volumes, it is a compact yet impactful work that VIZ Media has since brought to English-speaking audiences. The anime adaptation expanded on the original’s emotional beats, using music, pacing, and animation to heighten the tension and heartache at the core of the narrative.
With this sweep, Takopi’s Original Sin has joined the ranks of modern anime phenomena that dominate both critical acclaim and audience popularity. Its performance in the Summer 2025 rankings shows how deeply a well-crafted, emotionally resonant story can connect with audiences across the globe.
As the series steps aside with its finale aired, the weekly rankings are now open for a new champion to emerge. However, the legacy of Takopi’s five-week dominance will remain a highlight of the season and a benchmark for future contenders.
