- **Perfect Fit for the Episode** [05:12] — The episode's focus on realistic, weighty character acting and human interactions made it the perfect fit for Fujimoto's solo key animation effort.
- **Subtle Acting Animation** [06:02] — Fujimoto's subtle acting animation is 'perfect', with meticulous frame placements and a fantastic understanding of human movement, as seen in shots like Higuruma tapping his pen.
- **In-Your-Face Acting** [06:14] — The episode also features more exaggerated, in-your-face acting animation, which is still realistic and natural, with noticeable bounce in the motion.
- **Beyond Humans** [07:31] — Fujimoto's natural acting extends to animals and even inanimate objects, with cats and the ground being hand-animated by the animator.
- **Loose Drawing Style** [07:44] — The episode utilizes a blobby, abstract style of drawings with varying degrees of form, but Fujimoto never sacrifices the movement component, creating a unique visual dichotomy.
- **Constant Movement** [09:05] — The episode is packed with movement, from meticulously animated hand slaps to complex shots with multiple characters and perspective shifts, making it difficult to highlight every impressive scene.
- **Direction and Storyboards** [10:08] — Yusuke Takada stuck to Goshozono's philosophies, with long lingering shots, sporadic bursts of movement, layered compositions, and repetitive visual motifs.
- **Polished Animation** [10:36] — The episode is one of the most polished from the season, with few visible errors thanks to Fujimoto's incredible draftsmanship and the corrections by the animation director.
- **Background Issues** [10:50] — The only real issue is some background work, which looks like low-res hazy photographs, a minor fault but worth mentioning.
- **Complex Shots** [11:03] — The episode features complex shots with multiple characters, vehicles, and hand-animated backgrounds, which are time-consuming to draw but executed flawlessly.
- **Fight Scene** [11:42] — The fight scene feels real with tremendous weight in every motion, run-up, and strike, even the more cartoonish exchanges are presented naturally.
- **Higuruma-Yuji Confrontation** [12:58] — The confrontation features some of the best drawings of the season, with impressive rotation shots, colors, and liquid effects, culminating in a complex domain scene.
- **Final Thoughts** [14:03] — The creator praises Fujimoto as a 'madman' and looks forward to the remaining episodes, expecting them to be good, especially the last one.

### Conclusion

The episode is a masterpiece of solo key animation, showcasing Kouki Fujimoto's incredible talent for character acting and weighty movement. It's a must-watch for animation enthusiasts and a testament to the artistry behind Jujutsu Kaisen.

## Transcript

incredible in every sense of the word. From the overall direction and storyboards to the outstanding top-of-the-line 2D animation, it was a jaw-dropping display of artistry animated entirely by one guy, one key
animator. That's right. As some of you may know, the newest episode of JJK was solo key animated by one Kouki Fujimoto. He animated every single shot. I'll talk especially for a production like JJK, and what it means from a
behind-the-scenes point of view in a bit. Back to the energetic intro, the episode, like I said, was amazing. We had eye-catching framing, mind-blowing animation, phenomenal drawings, and an incredibly satisfying visual aesthetic.
one of the best-looking episodes from this show, in my opinion. And as such, let's break down the visuals. Make sure to subscribe. That subscribe button looks the best when pressed, and it helps out a lot. Come on, it takes a

As always, let's start with the staff list, and there's a lot worth talking directed and storyboarded by assistant director Shota Goshozono's seven-episode-long storyboarding streak,
While Goshozono not handling the storyboards for once doesn't surprise me, if anything, him storyboarding so many episodes was the real surprise, it still feels like a momentous occasion. I know Takada stuck closely to Goshozono's
like the show morphed into something completely different, but it's still definitely worth highlighting. Over on the animation side of things, we had one Yajima, one animation director for the first time since season 1. Well,
technically, that Tengen Yapp episode didn't have an AD credit, but I believe their own shots, so it doesn't count. One AD for the first time since season 1, Yazi Lu, who I actually remember making his Sakuga Booru tag myself, a
couple of assistant animation directors, and of course, one key animator, the aforementioned Koki Fujimoto. Let's start with the elephant in the room, solo key animation, a concept that always blows my mind, especially on this
scale. The idea of one guy picking up a pen and animating an entire episode over 20 straight minutes all by himself is, quite frankly, ridiculous. Now, yes, you can be pedantic about it. Yes, Koki Fujimoto didn't animate every
single frame himself. There were in-between animators, but look, I'm not in-betweening, but when we talk about animation, we usually say this scene was animated by Yutaka Nakamura, not this scene was animated by Yutaka Nakamura
and in-between animators, and that's for a reason. The key animator defines a shot. He or she draws all the key poses and decides how many in-betweens are needed and where, occasionally drawing actual in-between guides. They are the
key animators, the creative force behind a shot. Also, for what it's worth, Koki Fujimoto was credited as an in-between animator as well. animating this entire episode all by himself is, like I said, ridiculous, and
amount of movement. Again, I have trouble wrapping my head around the concept of an animator drawing so much and so well. Insane stuff. Now, what does all of that mean, you may ask. Why was this episode animated by
one guy? Did they run out of animators? Were they saving resources? Well, no. What it means is that this episode was in the oven for a long, long time. Think about it. One guy animating 20 minutes of content will obviously take a lot
longer than 10 or 20 guys doing the same. That's how things work. Plus, the episode had one CAD and one AD, usually the outcome of healthy conditions and a justifiable number of second key animators. Justifiable because one guy
of people cleaning them up is a production model that actually makes sense. It's a lot better than a bunch of guys drawing the layouts and a bunch of guys cleaning them up. Sure, some artists go even further. They animate an
and handle the cleanup. Takayuki Yanamihai by episode 6, what is wrong with you? Are you clinically insane? But there's nothing wrong with requiring cleanup help when you've animated an entire episode. That's perfectly fine.
Anyway, with all that being said, let's finally go through this episode. Fujimoto. I think that will help us unpack this episode better because, you know, he animated all of it. Fujimoto, as you could probably tell, is
outstanding at animating human motion, at animating character movement. His ability to make seemingly mundane actions feel natural and fluid is so to say he's one of the best character acting animators of our generation. He's
phenomenal. The sheer amount of weight he packs into his animation is simply otherworldly. That's the reason why his animation often gets mistaken for CGI and or rotoscopy. Also, just for the record, nothing in this episode was
rotoscoped. Heavily referenced, yes. This episode had a separate live-action references being Fujimoto himself, but not rotoscoped. Naturally, entrusting an artist like Fujimoto with an episode centered around
character acting, and not just acting, but the realistic, weighty kind of much on human interactions and society, it just made sense. Out of every single Jujutsu Kaisen episode, this was
probably the best fit for a Koki Fujimoto solo key animation effort. Right from the get-go, you could feel the natural vibe of the animation. This ultra-wide angle shot of Higuruma, for example, even though he is far away from
the camera, meaning there are lesser lines to manipulate, making it harder to visualize the movement, Fujimoto conveyed so much weight and personality all via a back profile where Higuruma takes up like 2% of the screen. You're
watching a master at work, boys and girls. This is it. Similarly, this simple shot of Higuruma tapping his pen had perfect weight control, the way the fingers recoil under the weight, the way the palm shifts back and forth. It's
ridiculous. I won't go over every shot in as much detail. We'd be here for point. Fujimoto's acting animation is very perfect, if that makes sense. Throughout the course of this episode,
subtle scenes like the ones I just in-your-face acting animation, and both styles were executed perfectly. These two shots, for example, he dialed up the bounce in the motion. They were still
realistic and natural, but the movement was more noticeable in a good way, of Just look at this shot. Look at the phenomenal volume control. Look how consistent the character drawings are. Look how alive the movement feels.
Meticulous and methodical frame placements, coupled with a fantastic understanding of human movement, absolutely incredible. I actually have a particularly strong sense of appreciation for this shot, because it's
a bit of a tangent, but it's my channel, off. As some of you may know, I'm and I'm animating a few shots for it myself, and one of the shots I'm currently working on is very similar to this one. Character walks and then turns
around, so I know firsthand how difficult shots like these are. Maybe not to Fujimoto, because he is who he is, but for the rest of us mere mortals, it's insanely difficult. Moving on, I love this shot. You know
natural-looking movement for one character? Animating natural-looking movement for seven characters. Also really like how the character models additional layer of shading and had the model be transparent beyond it. By the
way, Fujimoto's natural acting isn't just limited to humans. Even the cats course they are. Also quick shout-out to the ground underneath the sky and the car and in this shot for being cell as in drawn by the animator, not the
background artist. Before we move on, let's briefly address believe that's what they're called. I'm not entirely sure. Basically, it's that thing where characters have less detail
camera. Less detail in quotes because a more appropriate definition would be less form. For this episode, Fujimoto utilized this blobby abstract style of drawings with varying degrees of form. In most cases, he would omit facial
in some shots, he would make the entire body wobbly and stylized. Now, this does this. But the reason why I'm pointing it out is because Fujimoto never sacrificed the movement component. Even shots that look like this moved
like this. I was particularly fond of this sequence. The character models were incredibly loose and deformed, but the movement was perfectly lifelike, creating this weird visual dichotomy that I loved. Also, this shot was
insanely complex. So, you had multiple characters moving like their lives high angle plane and away from the means Fujimoto had to animate multiple subtle perspective shifts. I think most
casual viewers won't think much of shots like these, but they're incredibly difficult than your standard flashy action scene. Now, look. Realistically, I can't go over every impressive scene from this
episode. The thing simply moved too much. Is this a still of these two sitting? No, because here comes a well-animated mother and daughter. This guy slapped the glass. But of course, we can't just put hand.png on glass
window.jpeg and call it a day. We have to meticulously animate the weight behind the hand and the fingers pressing against the glass as a result. Just draw a close-up of Fuji climbing down the stairs. What are we? A normal anime? Of
course, we'll painstakingly animate his entire body going down each step one by one. Something that's notoriously difficult to do. You get the idea, right? This episode kept moving. The Koki Fujimoto character animation train
was firing on all cylinders. There's only so much I can talk about. Pretty much every shot in this episode deserves its flowers, but from now on I'll focus understand. Also, let's use this opportunity to talk
about a few non-Koki Fujimoto talking points. The direction, for example. Like I said earlier, this episode wasn't storyboarded by Shota Goshozono, but Yusuke Takada stuck to his philosophies. Long lingering shots of killer
course, the storyboards weren't as overtly eye-catching as the previous episodes, but they more than got the job done. You had these long shots with sporadic bursts of movement to keep the viewer engaged. You had layered complex
compositions. You had repetitive visual motifs. It was great. Besides that, episode 8 was one of, if not the most polished episode from this season. The and Lu's corrections, and despite featuring the largest amount of
could count on one hand the number of visible junk {slash} melt thanks to Fujimoto's incredible draftsmanship. Basically, the animation end was pretty much perfect. The only real issue I had with this episode was some of the
background work. Some of the BGs did look like low-res hazy photographs. The previous episode had a similar issue. Not a significant fault, but definitely worth mentioning. Anyway, let's get back to the breakdown.
I loved this shot. There was so much going on. The two important characters in the distance occasionally moving and the countless mob characters, vehicles, and mob characters on vehicles moving past the screen. So many different
things that had to be animated alongside the focus characters. Shortly afterwards, we got this really cool sequence. Obviously, the walking on top of that, the background was hand-animated. Crowds and backgrounds
are the two most time-consuming things and can draw, and this episode featured This frame was really cool. I loved the individual blood vessels in the eyes, the well-defined shading adding form and volume to the face, and the metric ton
of hatching. Amazing stuff. Although, the jump from the previous shot to this one was a bit abrupt and awkward. Gave it a very government-mandated manga I mean. I loved this scene. The force and
desperation in Higuruma's body language was conveyed through natural movement instead of exaggerated motion. It was truly remarkable. This was then followed by this shot where the entire room was hand-animated. We started with a front
side with some heavy foreshortening and then backwards turning into a low-angle background was animated accordingly. An insanely complex idea, but executed
The next highlight was the fight scene, and it was preceded by more incredible acting. I know I said I'll skip over these scenes, but just look at this. This is character acting of the highest level. This is season finale quality.
Absolutely mind-blowing. Anyway, back to the fight. I loved how real it felt. Every motion, every run-up, every strike, the entire thing had a tremendous amount of weight. Even the more cartoonish exchanges were
presented naturally. It's the kind of Chainsaw Man got dragged over the coals for, and it was insane. A bunch of top-tier acting, both subdued and in your face, then brought us to the Higuruma-Yuji confrontation, and it was
simply stellar. We started with some insanely polished drawings, some of the best of season 3, followed by this impressive rotation shot. Also loved the colors, especially in this shot. It was very over the top and in your face, but
red was actually really well implemented. Anyway, back to the animation. We got this gorgeous three-tone liquid animation and this complex high-angle shot with top-notch shading. This was
warping and distorting as judgment popped up and more liquid effects, really cool stuff. This shot was ridiculous. The camera tracked Yuji Itadori's legs and the entire background, the bathtub, the floor, the
stairs, all of it was hand-animated. It was then followed by more natural acting and finally, after all of that, we got the domain scene with a complex camera zoom out and pan, liquid effects, lots of background animation, and these easy
but beautiful impact frames. This was then followed by these intense flashing lights, which I believe were added by the compositing team. Amazing work. And that was the episode. Again, absolutely insane. Hats off to Koki
Fujimoto. He's a madman. Based on what I've heard, the remaining few episodes should be good, especially the last one, so I'm really looking forward to them. Of course, expect more JJK videos in the future. That's about it. A special
thanks to Noodle03, Ahmed, TheGallus90, and Sheikisan for becoming tier three and Sheikisan for becoming tier three members. And until next time.
