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.

Sakamoto Days, adapted from Yuto Suzuki's popular 2020 manga, blends action and humor masterfully. Protagonist Taro Sakamoto, once a legendary assassin, traded his deadly profession for domestic bliss—marriage, fatherhood, and running a small shop. His peaceful life is shattered when Shin, his former partner and protégé, arrives with orders to eliminate him. The now-domesticated assassin must protect his family from his past.
The series shines with its absurdly entertaining battles. Sakamoto, using everyday objects like chewing gum and ladles, counters attacks with incredible reflexes and ingenuity. He catches bullets with chopsticks, deflects them with gum, fights with pens, blocks attacks with spatulas and ladles, and dodges lethal blows at superhuman speeds.

The spectacular fight scenes are a highlight, each episode introducing a new antagonist with unique killing techniques. However, the series is also a comedy. Sakamoto's near-invulnerability is played for laughs, contrasting hilariously with his ordinary physique. The show doesn't shy away from poking fun at his omnipotence.
Contrasts form the foundation of the narrative
The series masterfully juxtaposes characters, storylines, and tone. Sakamoto, a principled family man with a dark past, balances household chores with protecting his family. His adversaries, equally complex, possess rich backstories and aren't simply bloodthirsty mercenaries. The series constantly subverts expectations: deadly situations become harmless, and seemingly ordinary individuals reveal psychopathic tendencies.

Top-notch animation in Sakamoto Days
Produced by TMS Entertainment (Dr. Stone, Detective Conan), the animation is top-tier shonen. Fight scenes are dynamic, utilizing impressive shadow contrasts and fluid motion to convey the action. Sakamoto's grace and Shin's Hollywood-esque maneuvers are beautifully animated.
Killing is bad: this message dominates the first four episodes

The series balances intense action with uplifting 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 message resonates, and its constant surprises keep it engaging.
