There’s no such thing as a former mercenary. For anime fans, 2025 began with a bang: the return of the historical detective series Pharmacist's Monologue and the sequel to the popular isekai Solo Leveling. But one standout is the brand-new 11-episode action series, Sakamoto Days, already topping Netflix Japan's charts. It's truly excellent, and here's why.

Taro Sakamoto, a retired hitman, traded assassinations for a life with his cashier wife and daughter. Now, his past catches up.
Sakamoto Days adapts Yuto Suzuki's manga (launched in 2020), quickly gaining popularity for its action-comedy blend. Protagonist Taro Sakamoto, once a legendary assassin, unexpectedly fell for a grocery store cashier, retiring to a peaceful life running a small shop. His quiet existence is shattered by the arrival of Shin, his former partner, tasked with eliminating him—because you can't just quit being a killer. Sakamoto must protect his family from his deadly past.
The series shines with absurd battles: Sakamoto catches bullets with chewing gum and fights with kitchen utensils!

Sakamoto Days' spectacular fight scenes are a highlight. Each episode introduces a new antagonist with unique killing techniques. Sakamoto, however, rarely uses weapons, relying on wit and reflexes, creatively adapting everyday objects: chopsticks, chewing gum, pens, spatulas, ladles—all become weapons in his arsenal. His superhuman speed and agility are incredible.

The series shouldn't be taken too seriously; it's a comedy. Sakamoto's near-invulnerability is either embraced or a deal-breaker. The show cleverly satirizes his omnipotence, contrasting it with his ordinary physique.
Contrasts form the foundation of the narrative
The show masterfully juxtaposes characters, storylines, and tone. Sakamoto, a principled family man with a dark past, balances household chores with the fear of divorce over assassinations. He even employs former adversaries, offering jobs and overtime! His adversaries are equally complex, possessing rich backstories and unexpected empathy. The lines between deadly and harmless constantly blur. A potential killer might change sides, while an ordinary pizza delivery guy could be a psychopath.

Top-notch animation in Sakamoto Days
TMS Entertainment (Dr. Stone, Detective Conan) delivers top-tier shonen animation. Fight scenes are dynamic, with masterful shadow play and fluid motion. Sakamoto's grace contrasts with Shin's classic Hollywood action hero style.
Killing is bad: this message dominates the first four episodes

The series balances intense action with heartwarming family comedy. The fights aren't just spectacle; they reveal character depth and enhance relationships. Sakamoto Days is enjoyable, blending humor, well-choreographed battles, and a lighthearted script. Its moral compass resonates, and the series constantly surprises.
