Everyone Assumed It Was a Watercolor Filter. The Anime Ending Was Painted by Hand, Frame by Frame

A making-of video for the ending of Jaadugar: A Witch in Mongolia reveals that every frame was painted in real watercolor.

Everyone Assumed It Was a Watercolor Filter. The Anime Ending Was Painted by Hand, Frame by Frame

What's going on

Jaadugar: A Witch in Mongolia is a TV anime that started airing in Japan in July 2026. It's based on Tomato Soup's acclaimed manga A Witch's Life in Mongol, and follows Sitara, a former slave girl in the 13th-century Mongol Empire who uses her wits to shake the empire from the inside. It's made by Science SARU, the studio behind DAN DA DAN and The Heike Story.

The show's ending sequence has a soft, bleeding watercolor look. Most viewers assumed it was a digital effect. Japanese TV anime switched to computer coloring around the turn of the century, and hand-painting animation frames is now almost unheard of. Then the studio shared a making-of video from Kiiro Aose, the artist behind the ending, showing that every single frame had been painted by hand in transparent watercolor.

Animation needs a lot of drawings for even a few seconds of movement, so viewers were stunned by how much work that meant. With AI-generated images a constant topic of debate, a few people also pointed out what the video says about handmade work.

Here’s the making-of for the Jaadugar: A Witch in Mongolia ED animation🎨

I finished it one sheet at a time in transparent watercolor.

The full-length version is in the quoted post🎥

Key animation was done by Tsubasa Morimoto🙇‍♀️ Thank you so much for the wonderful animation😭✨
原画は森本翼さんが担当してくださいました🙇‍♀️素晴らしいアニメーションをありがとうございました😭✨
Such nostalgic watercolors, like the ED of a Showa-era TV anime! Think Toei’s Tongari Boushi no Memoru or Maple Town. The one below is the ED from Maple Town: Palm Town Arc. (Both are 1980s TV anime from Toei Animation. The Showa era ran until 1989.)
昭和のTVアニメのEDを思わせるノスタルジックな水彩画ね!例えば、東映の「とんがり帽子のメモル」や「メイプルタウン物語」のような。下は、「メイプルタウン物語 パームタウン編」ED
Wait, this looks less like a watercolor effect and more like actual watercolor? Nah, nobody does something that insanely hard these days… and then it turns out they really painted every frame in watercolor, whoaaaaa!!! Please do an original art exhibition!!!
水彩の加工というよりガチの水彩っぽいな?いやそんなクソ大変な事今時するわけ...って思ったら ガチで水彩で1枚1枚描いてたすげーーーッッッ 原画展とかやってほしい!!!
This is just too good… I already pre-ordered the Blu-rays the day they opened, but even if I hadn’t, seeing this would’ve sent me straight to buy them. Grateful. You have my respect.
素晴らしすぎる…円盤予約開始時に購入手続きしたけど、よしんばしていなかったとしても、これを見たら即買いに走ってたと思う。ありがたい。敬意を表します。
This is something else. Ever since Eizouken I’ve figured this studio doesn’t miss, and this just proves me right again. (Keep Your Hands Off Eizouken! is a 2020 Science SARU series about high school girls making anime.)
これは凄え 映像研以来この製作会社の作品はハズレがないとふんだのは間違いではなかったのが改めて確認できた
Σ🙉 H-hand-painted!! I was wondering how they colored it, and it turns out they just did it the old-fashioned way. I bow before you m(_ _)m kneels
Σ🙉て、手塗り!!どうやって着彩してるんだろ、と思ったら正攻法とは。恐れ入りましたm(_ _)m ハハー
Classic Ms. Yamada. I figured there was some effect technique for that see-through watercolor look, but it’s actual watercolor‼️ (Naoko Yamada, known for K-On! and A Silent Voice, is the show’s executive director.)
流石山田女史、水彩画っぽい透明感あるエフェクト技法があるんだろうなと思ったらほんとに水彩‼️
Makes me want to sit down and really take in this watercolor making-of…! So Kiiro Aose’s brushwork is where the warmth of the ending comes from.
水彩のメイキング映像、じっくり見たくなります…!青瀬きいろさんの筆づかいがエンディングの温かさに繋がってるんですね。
The hand of god, right there… (о´∀`о)
神の手や…(о´∀`о)
No sane person would do this (in a good way)
正気の沙汰じゃ無い(いい意味で)
What I love is that Science SARU, a studio that’s been pushing Flash and computer-driven animation for ages, can also direct something in this direction. (Science SARU is known for building its production process around Flash-based digital animation.)
サイエンスSARUという、かなり以前からFlashなどPC自動生成を追究してきたプロダクションがこの方向もディレクションできることが素敵だと思う。
N-no way
ま、マジか
Huh???????????????? You’re kidding me………………………… insane……
は???????????????? まじかよ…………………………ぱねぇ……
Th-that’s just too amazing
す、凄すぎますね
Such lovely colors in this animation. Thanks for the making-of. Footage beautiful enough to rewatch again and again takes real effort. Watching the shading come together by hand gave me chills.
素敵な色合いのアニメーションですね。メイキング映像ありがとうございます。 何度も見られる美しい映像というのは手間が掛かっている。手書きで濃淡が仕上がっていく様子に痺れました。

I mean, I’d been thinking “wow, that looks pretty…” but hand-finished watercolor?! Of all things!

Science SARU, there’s no measuring how unique you are. Your ideas and execution are true craftsmanship. You’re the pride of Japanese animation.

いや、表現が「奇麗だなぁ・・・」って思っていたけど まさかの「手仕上げの水彩画」! 「サイエンスSARU」さん、あなたたちのユニークは計り知れない。 発想と表現はまさに職人。日本アニメの誇りです。
Just watching this got me all fired up
これを拝見しただけで熱い気持ちになりました
Wait, that was ALL hand-painted watercolor?!
あれ全部水彩絵手書きだったの!?
Seriously, all of it is watercolor?! Σ(゚∀゚ノ)ノ
マジで全部水彩なのか!? Σ(゚∀゚ノ)ノ
So animators can recreate characters and worlds that aren’t even in their own art style this well… amazing
アニメーターの方って、元々は自分の絵柄ではないキャラや世界をこんなにも再現できるんですね…すごい
They’ve lost it…
イカれてる…
Amazing, amazing. Showing the process too really brings out the value of handmade work, the kind AI can’t produce.
すごいすごい。このプロセスも含めて見せることでAIには出せない手書きの価値が出てきますねー。
Now this is craftsmanship AI can’t copy
これはAIには真似できない職人技だな
So the warmth in the art comes from all this effort and care… Amazing… way too amazing
絵に暖かみがあるのはこんな苦労や手間があったからなのか… すごい…すごすぎる
Watching this, I honestly wondered if they’d lost their minds (in a good way). The passion is off the charts. Can we call this the top show of the season already?
これを拝見して良い意味で頭イカれてるのかと思った。 熱量半端ない。 今季覇権作と言って良いのでは?

It’s such a gorgeous watercolor animation, so is it hand-painted…?? No, surely it’s digital these days…?? Impressive either way..

That’s what I was thinking, but it really is handwork.. No flicker, a flowing painted texture, delicate colors. Divine skill..

滅茶苦茶美しい水彩アニメーションだから、手書き…??いや、今日日デジタルか…??どちらにせよ凄いが。。 と思ってたけれど 手仕事なのですね。。 パカパカせずに、流れのある塗り味、繊細な色合い。神業です。。
Such delicate work, wonderful…! Beautiful…
繊細なお仕事素晴らしいです…! 美しい…
The bleeds and wobble you only get from transparent watercolor suit the animation so well. Flip through the frames and you can feel the wind and smell the air The passion and love for the show is something else..
透明水彩特有のにじみと揺らぎがアニメーションに凄くマッチしていて、パラパラとめくった時に風と匂いを感じる 作品に対する情熱と愛が凄い。。
Watching the process makes me dizzy, but it’s so lovely… the color gradients and bleeds are just the best✨ I saw the anime ED earlier too and it got me going WAAAAH! so moved
作業見ると気が遠くなるけど、めっちゃ素敵だな…色のグラデーションとにじみが最高すぎる✨ 前お見かけした、アニメのEDもウワーーーッ!て感動しました

Seeing handwork like this makes me love the show even more, and makes me go “I want to see the actual paintings from the making-of!”

And then I’d go to an original art exhibition and grin at the knife marks from cutting the masking and the fuzzed-up paper on top (Masking is tape or film laid over parts of the paper so the paint doesn’t go where it shouldn’t.)

こういう手作業見ると作品がさらに好きになるしメイキングの実物画みたい!てなるです! そして原画展とか見てマスキング切ったカッターの傷とか上の毛羽立ちとか見てニコニコするのです
So good I’m shaking…
凄すぎて震える…
For Banjo here, who’s bad at color, all I can say is “amazing”
カラーが苦手なバンジョーにとってはひたすら凄いの一言
Hand-painted… watercolor… seriously…? Amaz…ing…
手描き...水彩...ですかっ...すご...っ
Every single frame in watercolor…? What does that even mean…
1枚1枚水彩…?どういうこと…
Amazing. I love this cut so much I tried copying it, but they masked and painted each in-between frame one by one? What an insane amount of work.
すごい。このカット好きなので模写したけど、動画1枚ずつマスキングして描いてるんですね。なんという手間。
Tried painting Sitara in transparent watercolor.
透明水彩でシタラちゃん描いてみた。
N-no way I’m shuddering…
う…嘘だろ 戦慄している…
This kind of work takes serious skill, labor, and money, right? Even if a director said they wanted to do it, I think most productions would struggle to sign off on it. These days even harmony shots are tough to pull off, for all sorts of reasons. (A “harmony” is a classic anime technique where a moving shot freezes into a hand-painted still, famously used by director Osamu Dezaki.)
これってすごい技術と労力とお金が掛かる仕事ですよね。 たとえ監督がやりたいって言い出しても、なかなか許可できないラインが殆どだと思います。 現在ではハーモニーも諸々の事情で難しいですからね。

My take

Honestly, where does Japan's passion for anime even come from?
