First Look: Winter 2025 Anime Overview: ZENSHU

Premise: Natsuko Hirose is an animator and director lauded as a genius, but she’s struggling with her newest movie, insisting on doing everything herself. Then she dies from food poisoning and is transported to the world of her favorite anime movie, the one that inspired her career. Natsuko finds she has the power to literally draw and animate beings that will then fight the monsters attacking them—can she use her power to save the day and avoid the movie’s tragic ending?

Zenshu is a love letter to animation, artistic inspiration, and stories in general. I’ve been waiting for an isekai anime that actually uses the “transported into the world of my favorite piece of media” in a creative and meaningful way that explores storytelling and the ramifications of interacting with a narrative, and Zenshu is finally it.

Natsuko is struggling with creating a movie about "first love" because she’s never had one, and then bam, she’s transported into the world of A Tale of Perishing, a movie that flopped hard (likely due in part to how depressing the ending is) but it’s been Natsuko’s favorite since childhood and was what inspired her to become an animator.

Natsuko specifically using her animation prowess to save the day is just also an amazing idea, and it looks great. She basically pulls out her pegboard, and then undergoes a magical girl transformation that just ends with her being at her desk. The animation she creates then rises up and beats the monsters, and they’re usually references to something—the first one being the God warrior from Nausicaa.

There’s a lot of fun little gags, like her needing to sleep for three days after because that’s how long that sequence would normally take to animate and a lot of little nerdy in-jokes, like Natsuko being in rapture at finally getting to eat anime food, or coming up with a sentai pose for her team.

(And speaking of references, Natsuko's first hit show was a clear combination of Sukeban Deka and Sailor Moon, which I now dearly want to exist in real life).

Suiting a show about an animator, the animation for the series is consistently gorgeous and full of individuality. The humor of the series is also on point, and you can see the strengths of the director and screenwriter duo of Mitsue Yamazaki and Kimiko Ueno. The two women previously worked together on adapting Gekkan Shoujo Nozaki-Kun, one of my favorite anime, and you can see that comedic timing reflected here.

Natsuko is a fun and relatable character, avoiding some of the typical tropes for anime girl leads- she’s an adult, she spends the entire anime in an oversized hoodie and jeans and a lot of it with her hair covering her face Cousin It style, and when her “style” is pointed out as sloppy, her response is “I’ll dress how I want”. She’s cynical and sarcastic and a huge nerd. It’s fun to see her automatically clash with the characters she’s loved since she was a child, showing that characters we love can be annoying as real life people, which I’ve always wanted isekai to explore.

The other characters are fun too—Luke is our stereotypical Hero character, but spending all his time fighting evil has actually made him extremely socially clueless, and he reveals himself pretty adorable after a while. Natsuko and the cute little mascot unicorn hate each other on sight, and it’s incredibly fun.

The often puts a clever twist on some tired tropes—Natsuko runs into Luke’s damsel in distress love interest (who's supposed to end up fridged, to boot, and rather than fight with her over Luke, Natsuko leads her to realize she actually has agency and can be whoever she wants—the result is amazing, and includes some lighthearted criticism of misogynist narratives. I go into it in detail on this post, minor spoilers.

The show is also very queer positive. We’re introduced to a dragon-person who, in the dub, uses they-them pronouns. In the sub, some viewers interpret them as a lesbian, but yeah, queer regardless, and Natsuko indicates some mild physical attraction to them. They’re also a great character.

One episode goes into the people who have crushed on Natsuko over the years (while she remains oblivious) and the first one is a young girl and classmate of hers, who identifies Natsuko as her first love. I go into more detail about how sweet it is in this post. It’s just a very casually queer show, and I appreciate that.

The themes of the story are interesting, the show explores the pressures of being a creator, the way you can shut others out and insist you know best, and what inspiration is. Natsuko begins to struggle with the fact A Tale of Perishing is her favorite movie in part because of how it puts a more dour spin on a fantasy story, and it's inspired her so much...but now the characters are real people she cares about. So she has to stop their fates even if it messes with the creator’s vision. But the question is, CAN SHE, or are they literally doomed by the narrative?

The ending is where things get a little muddled. It isn’t bad, but it’s rushed compared to the rest of the show, and feels a little too easy. I wish Natsuko had interacted way more with the original creator and we’d really gotten a clash of opposing viewpoints. I feel we barely scratched the surface.

Going slightly into spoilers territory with this paragraph, skip if you don't want any. The ending I think, can either be interpreted as either 1. Fanworks and interpretations are valid as hell and creators who look down on them are wrong (this is a bit of a stretch since the series doesn’t mention fanfic or doujinshi at any other point) or 2. It’s fine to take inspiration from your creative heroes, but you have to be willing to do something different, and accept the support of others. Conversely, a creator that is too precious about their work, who shuts out others and who looks down on those who take inspiration from them because they’re doing something different, is wrong and misguided.

That’s my best guess, but the themes get weirdly muddled in the last episode, in a way it takes some serious thinking to decipher a message that’s super applicable to real life. Like “these characters are real people now” is a nice motivation and drama, but not one that seems to a ton about art, though it does play into the theme that Natsuko needs to learn to let others in and connect to them.

Like I said, it’s not a bad ending, I was happy with it, it just felt a little undercooked. I would have liked to see some more themes and characters explored. The show’s message about art could have been stronger, and it left some potentially really interesting and meaningful stuff on the table...but it was still amazing. I loved its creativity and characters all the way through.

The story is good, the characters are loveable, and the animation is incredible. This has already earned it’s place on the top anime of the year list and I really implore you to check it out if you love anime and art at all! It's a thoroughly good time.
