In this episode it is very exciting because the Touma is determined to find the truth who is the traitor of Sword of LogosKamiyama, a young novelist and bookshop owner as he is drawn into a fantastical battle between warring knights, featuring fairy tale settings, dangerous monsters, and all while and meeting a myriad of characters along the way.
Kamen rider Saber is the second Reiwa Era Kamen Rider series and as such you can feel the show trying to find its identity. If you are familiar with Kamen Rider the first episode feels a bit like W or OOO tonally, but it shifts into a tone that reminds me of Kamen Rider Wizard and Super Sentai (please don't be scared off by that comparison though!)
Right now we are a little early into the show's run (I am writing this just a couple hours after watching the fourth episode), so it is difficult to gauge the overall quality of the show, however currently the show has a lot of potential, but is being held back by odd pacing and an upsetting overuse of stock footage.
The main strength of the show as it stands over the writer's previous contribution to the franchise (Kamen Rider Ghost) is the characters and acting. While the characters are still a bit flat everyone has defined personality traits, and no one feels too similar to anyone else. The actors seem like they are having a lot of fun, and in particular I quite like the actor for Touma.
