Manji is an infamous swordsman in feudal Japan who is known as the "Hundred Man Killer," as he has killed one hundred innocent men. However, there is something far more frightening than his ominous reputation: the fact that he is immortal. This is the handiwork of eight-hundred-year-old nun Yaobikuni, who placed bloodworms capable of healing almost any wound in Manji's body.

To atone for his crimes, Manji resolves to kill one thousand evil men. Yaobikuni agrees to this proposal, saying that if he succeeds, she will undo his curse of immortality. Soon after this promise, Manji meets Rin Asano, a 16-year-old girl who requests Manji's assistance in killing those who slaughtered her parents.

Initially reluctant, Manji refuses Rin's desperate plea. However, owing to her evident lack of strength, Manji changes his mind and agrees to protect Rin for four years. With this partnership set in stone, the two embark on a perilous journey of bloodshed, vengeance, and redemption, each to fulfill their own life's cause.

This was a great show. It started out rough. I didn't like the first three episodes that much, but I was drawn to the character and the concept so I stuck with it. I like the more adult/violent stuff... And this has an immortal wisecracking samurai. What's not to love? I couldn't be any happier about my decision to stick with the show more so than how I feel today having watched the finale. That was excellent. From episode 4/5 to the end I had a blast watching this every week alongside Vinland Saga in the fall, and alongside Dorohedoro this season. It was consistently ...

What defines a disappointment isn’t what you got, it’s what you expected.

Blade of the Immortal is one of the most illustrious manga titles to date on the back of its artwork alone. No critic worth their salt has ever paraded Blade of the Immortal on the quality of its writing, characterization, storytelling—none of it. It’s all on the art. And rightfully so, so when I see it getting adapted by LIDENFILMS, a studio whose prettiest production to date, Hanebado!, had to rely on the trusty ol’ rotoscope to stay standing for even a single cour, the last thing I expected was an anime which ...

I never thought I'd ever say this. Go watch the live action movie, don't waste your time with the anime. Spoilers ahead.

I love anime set in the samurai era, unfortunately this one was a mess. I can't tell if it's because the source material is awful or the adaption was awful because the live action which was extremely trimmed down was pretty enjoyable, but the anime which had far more content (that was still rushed), was far less enjoyable, and frankly sucked. Here's why.

The fundamental story of BoTI is solid and very fitting. The arcs and the villains however are pathetically executed. First the arcs. ...
