Jubei-chan the Ninja Girl: Secret of the Lovely Eyepatch
Oshimeter
Synopsis
Just a regular 14-year-old living her best life, Jiyu Nanohana has no idea what's coming until a scatterbrained 300-year-old samurai shows up and hands her a heart-shaped eyepatch that turns her into the reincarnation of legendary swordsman Yagyu Jubei. That's the kind of show this is. It's a 13-episode TV series from Madhouse that smashes together magical girl transformation sequences with legit samurai duels, and somehow the whole thing just works. Jiyu's got school drama, a sweet relationship with her ghostwriter dad, and a rival clan called the Ryujoji who've been nursing a grudge for centuries and keep sending warriors after her in increasingly ridiculous situations. The comedy hits genuinely well: Koinosuke, her ancient samurai guide, is a complete disaster of a mentor, but the show also knows when to slow down and let the emotional beats land. Think of it as what you'd get if Sailor Moon's transformation concept collided with Rurouni Kenshin's swordplay and Ranma ½'s chaotic energy, all filtered through a late-90s Madhouse aesthetic that still looks sharp. The 'Lovely Eyepatch' as a transformation device is such a weird choice that it circles back around to being genuinely cool. At only 13 episodes it never overstays its welcome, and the blend of historical grudge matches with modern school life gives it a personality that's hard to find anywhere else. If you're into genre mashups that commit fully to the bit, this one's worth your time.

The action scenes in this finale were really good and made it a lot of fun to watch. My favorite part was Jiyu Nanohana and Sai Nanohana’s bond, which added a lot of heart to the anime and made the finale even more satisfying.
The story, plot, and overall direction are really good in this episode, and it was genuinely interesting to watch. Things are getting exciting now, and I can’t wait to see how the finale turns out!
This was a great episode, and I really enjoyed its darker tone. The shift in atmosphere made the episode feel more intense and impactful, making it one of the better episodes so far.
The playful vibe is slowly fading as the story gets more serious, and Jiyu’s struggles feel much more real now. The sense of urgency makes everything feel more personal, and honestly, the story is getting really good.
This was a pretty decent episode with a few fun and lighthearted moments. It was an nice watch overall, even if it wasn’t anything too special.
Sai Nanohana’s past was really emotional and heartbreaking to watch. It added more depth to his character, and overall, this was a really nice and impactful episode.
As the anime reaches its midpoint, this episode feels like a solid turning point. The story is getting more interesting, and things are finally starting to come together.
The uneven pacing makes the plot feel less engaging and affects the overall flow of the episode. Hopefully, the story picks up the pace and becomes more interesting in the upcoming episodes.
This episode was really good and fun to watch. The father-daughter scenes were especially wholesome and added a lot of warmth to the episode, making it even more enjoyable.
This episode feels like things are finally starting to pick up. The pacing and nighttime visuals were my favorite, especially the beautiful night sky and moon it looked absolutely stunning.
This episode was okay overall, but it felt a bit random and lacked a clear flow. The story and character development are progressing quite slowly, so I hope the pacing picks up in the upcoming episodes.
I genuinely didn't expect the show to stick the landing this well. The finale delivers some of the best action of the series but the real win is how well it resolves Jiyu's will vs duty conflict. It acknowledges the tragedy without becoming hopeless.
Sai and Jiyu's relationship is absolutely the heart of this episode. The fear, blame, and love between them feels really genuine. The supernatural plot is a bit confusing but the action and pacing make the lead up to the finale hit hard.
Wow this episode gets dark. The eyepatch's burden finally gets the serious treatment it deserves and I think Jiyu's internal conflict is easily some of the best writing in the series. The shadow heavy direction also looks fantastic.
The stakes finally feel real here. I like how the Ryujoji clan's curse creates an immediate sense of danger and the Jiyu, Sai and villain scenes are genuinely compelling. The problem is the constant bypass into school comedy which completely kills the tension whenever they appear.
After how hard episode 8 hit this feels like a bit of a step backward. I liked the continued family drama but the return of the villains makes the tone feel messy. Some of the jokes land but Bantaro's presence continues to just be loud filler that artificially extends the runtime. Still, the father-daughter moments save it.
We get to see some good character development for Jubei, which adds depth to the story. However, the pacing feels a little slow at times, making the episode drag in certain parts.
It was a nice start to the series, and I really enjoyed Jiyu Nanohana and Sai Nanohana’s dynamic. Their combo was one of the highlights for me, and I can’t wait to see more of them in the upcoming episodes.
This was an uneven series for me overall. Some episodes dragged, the humor could be difficult to digest, and there were definitely moments where its age showed. Yet the characters gradually became more endearing than I expected, particularly Jiyu and Sai. It may not completely match my taste, but it has such a specific identity that I can understand why it has its audience.
It’s interesting how different the series feels compared with those first few episodes. The storytelling is more serious now, although some moments still linger longer than I think they need to. That older pacing is probably something I’ll never completely adjust to, but the stronger atmosphere makes it less noticeable here.
