The World's Finest Assassin was a breath of fresh air in the Isekai genre of shows and did a lot to make itself stand out from the rest of the pack. The plot is great, the characters even better, and if the show had better production and pacing, we would have had a classic in our hands.
The World's Finest Assassin Episode 12 was the perfect finale for the series and helped it go out with a bang. The show picked up its tracks quite well in the last two episodes, which was great to see.
The World's Finest Assassin Episode 11 was a necessary and delightful return to the show's action roots, even though it required one to jump through many logical loops and bad animation to do that.
The World's Finest Assassin Episode 10 was boring, useless, and almost unwatchable. Just watch the first and last 90 seconds and skip the rest of the episode. You'll thank me later.
The World's Finest Assassin Episode 9 was an uncomfortable watch for all the wrong reasons. Can we have some more magic and assassinations instead of weird romantic subplots?
The World's Finest Assassin Episode 8 was great. While it wasn't the best or the most entertaining episode of the show, it was certainly still fun to watch and grounded in reality to boot.
