[00:00] is sane. But we know that you photoable

[00:02] has decided to make not one, not two,

[00:05] but three movies to conclude the story.

[00:08] Going to breaking down step by step what

[00:09] are the risk factors, what are the

[00:11] things that we need in the movie. Let's

[00:13] get into it. So first of all, let's

[00:14] start with what is even the Infinity

[00:17] Castle arc? There will not be spoilers.

[00:19] What is even the Infinity Castle arc?

[00:21] Okay, one might ask. For those who

[00:23] haven't read the manga, Infinity Castle

[00:25] is pretty much like Demon Slayer's

[00:27] Endgame arc. It's the conclusion and it

[00:30] is the most brutal arc of Demon Slayer.

[00:32] Some people think that season 2 was the

[00:35] best season and I think it's it is the

[00:37] best, but this is the most brutal season

[00:39] and the best one in my opinion. And this

[00:41] is not going to be a season going to be

[00:43] a movie. This takes place inside the

[00:45] Infinity Castle. We saw that all of them

[00:48] fell into Infinity Castle at the end of

[00:51] season 5. The Hashias are split across

[00:54] the domain. Everyone is scattered

[00:57] throughout the infinite domain of

[00:59] Infinity Castle. So, everyone is in

[01:02] different spots. No one knows where the

[01:04] others are. So far, what we do know for

[01:06] sure, Inoski is alone. Zenitsu is alone.

[01:09] And by the way, he's locked in. Everyone

[01:11] fell into Infinity Castle, but he

[01:13] entered. Guanro, they're both together.

[01:15] I guess Mitsuri and Canal are fell

[01:18] together. The mist hasher, the wind

[01:20] hashifra and the stone hashra they fell

[01:23] together. At least that's what I think

[01:25] they felt like. And then obai egro and

[01:27] mitsuri conroji are both together too.

[01:30] Now fun thing is that they are inside

[01:32] the castle. And guys, let me tell you,

[01:34] you guys are not ready for what's about

[01:36] to happen. Like I said, this is the most

[01:39] brutal arc of Demon Slayer ever. And

[01:42] it's also the conclusion. It's not just

[01:43] about fighting anymore. Let me tell you,

[01:45] it's not just about fighting. It's about

[01:47] sacrifice, legacy, and death. Now, let's

[01:50] talk about why you photoable chose

[01:53] movies and not a TV season. I think this

[01:56] is the the best decision they could

[01:57] make. And the reason why I think making

[01:59] movies was a better decision was because

[02:01] the animation level of Demon Slayer, the

[02:04] visual level is so god tier that it

[02:07] actually deserves to be a movie. It's

[02:09] beyond TV seasons. If you remember

[02:11] season 2 specifically and pretty much

[02:14] every season of Demon Slayer when it

[02:16] ends, when the credits are rolling, they

[02:18] actually roll it like movie and the

[02:20] animation is movie level animation. So I

[02:24] believe that making three movies to

[02:26] conclude the story is the best decision

[02:28] they could make. I am in the favor of it

[02:30] and it actually helps Demon Slayer to

[02:33] have much wider audience for those

[02:35] people who still by any chance not know

[02:37] about Demon Slayer will get to know

[02:38] about Demon Slayer. Let's break it down

[02:40] why it wouldn't work as weekly shown in

[02:43] anime. First of all, let's keep history

[02:45] in mind because Mugan Train made over

[02:47] 500 million US dollars on the box office

[02:50] which is crazy. For more than 20 years,

[02:52] for more than two decades, Haya

[02:54] Miyazaki's Spirited Away, the famous

[02:57] anime movie dominated the anime movie

[03:00] world with it being the highest crossing

[03:02] anime movie ever made with over $300

[03:04] million. But the moment Mugan training

[03:06] came in, it dominated the world of anime

[03:09] movies again. And this time, not just

[03:11] breaking the records, but actually

[03:13] making more records. It grossed over 500

[03:15] million. So this shows that there is

[03:18] something about Demon Slayer that

[03:19] connects with people on a much deeper

[03:22] level, on a spiritual level even because

[03:24] people cry. People cry their eyes out at

[03:27] the end of Mugan Train. That movie is

[03:29] not only sad, not only emotional, but

[03:32] also very impactful. It completely

[03:35] changed the cinema for anime. It build a

[03:37] new foundation for anime in the world.

[03:39] It's releasing in July 18. It's

[03:41] releasing on July 18 in Japan and on

[03:44] streaming services on Toho and then in

[03:47] September 18 in USA and Canada. I

[03:49] believe this would be a perfect chance

[03:51] for them to dominate the summertime box

[03:54] office because this movie is going to

[03:56] make a lot of money. Let me tell you

[03:57] something and you guys are not ready for

[03:59] what's about to happen. This is going to

[04:02] be crazy. For those who have not read

[04:04] the manga, you have no idea what's

[04:06] coming for you, buddy. Be ready for

[04:07] deaths. I'm I'm telling you one thing.

[04:09] Be ready for deaths. They're going to be

[04:11] a lot of deaths. There's going to be

[04:13] sacrifice. There's going to be emotional

[04:15] turmoil. Be ready. But shit's about to

[04:17] hit the fan. Let me tell you, it's going

[04:19] to be amazing. Let's talk about the

[04:21] emotional and psychological weight of

[04:24] this arc. And of course, movies, too,

[04:26] but this arc specifically. There are

[04:28] some specific hasheras which have some

[04:30] personal vendetta against uh some upper

[04:34] moons. Some will experience loss. Some

[04:36] will experience irreversible growth.

[04:39] Everyone will be changed after this arc

[04:41] cuz this is the defining arc. A lot of

[04:44] things are going to happen in this arc

[04:46] which people will people will remember

[04:48] forever. In the future when people will

[04:51] remember Demon Slayer, they're going to

[04:52] remember this arc. Whenever the whenever

[04:55] someone will talk about Demon Slayer,

[04:57] they will immediately start to remember

[04:59] the Infinity Castle art. That's how

[05:01] impactful it's going to be. These are

[05:03] going to be the defining moments of

[05:04] Demon Slayer's entire story. Let's

[05:08] address the elephant in the room, the

[05:09] euphortable factor, animation beyond

[05:12] logic. We all know that Euphfordable is

[05:15] one of the best anime studios ever to

[05:17] exist. Because Demon Slayer isn't uh the

[05:20] anime through which they have made their

[05:22] name. Even before Demon Slayer, they

[05:24] have made their name through Fate

[05:25] series. They have dominated the anime

[05:28] industry by how god tier their animation

[05:30] is. Now, let's break it down. What can

[05:33] we expect through the animation? It's

[05:34] going to be good. You photoable isn't

[05:36] just animating. They are directing

[05:39] cinema because it's going to be movie.

[05:41] So, they won't have to censor a lot of

[05:43] things which they would have done or

[05:45] would have to do if it was in weekly

[05:48] shown anime release. uh because they

[05:51] would have to sensor a lot of things for

[05:53] TV streaming and that would that would

[05:55] just kill the vibe. Other than this,

[05:57] they're actually using 3D technology in

[05:59] it too. I'm not talking about CGI. I'm

[06:01] talking about other 3D spatial

[06:04] environments inside castle movements.

[06:06] And each fight has a movie level

[06:08] choreography because this is not going

[06:10] to be an anime release. So, they would

[06:12] have to meet the standards of a movie.

[06:14] And what's rumored, each movie is

[06:17] getting above $20 million of budget,

[06:20] which is insane. $20 million of budget

[06:23] for every single movie. So there are

[06:25] three movies. 2x3 is six. So 60 million

[06:28] of total, 20 million on each movie.

[06:30] They're going to I cannot even begin to

[06:33] imagine what craziness are they cooking

[06:36] even as we speak. And okay, there are

[06:38] some chances why this could fail. Now,

[06:40] the chances are very slim because Demon

[06:42] Slayer is a very popular anime and a

[06:45] very successful franchise by now, but

[06:47] there's a slim chance why this could

[06:50] fail or disappoint fans. Let's break

[06:53] this down. It's logical that a high

[06:55] expectation equals high risk. But I'm

[06:57] pretty sure that high expectation will

[06:59] be met by high standards of quality. So,

[07:02] we know you affordable how they are.

[07:04] They are always ready to give us with

[07:06] something peak. Now, will the movie

[07:08] format rush major deaths? They're going

[07:11] to be a lot of deaths. So, will they

[07:12] rush some major deaths? If each movie,

[07:15] if I believe, if each movie is given

[07:17] about 2 hours and 30 minutes of run

[07:20] time, if each movie is given at least 2

[07:22] hours, 20 minutes, 2 hours, 30 minutes

[07:25] or even just 2 hours, but strong and

[07:27] even 2 hours, I believe that they could

[07:31] have some very fine pacing with the

[07:33] story. So pacing will not be affected at

[07:37] all. Another question that is raised is

[07:39] can they handle character depth in three

[07:42] parts? That's a good question. I think

[07:44] they can. It's just my opinion, my

[07:46] belief, and my hope. And I'm I'm sure

[07:48] they can do it. I'm 95% sure they can do

[07:51] it because they have not disappointed us

[07:53] in the past. So there's a very high

[07:55] chance they will not disappoint us this

[07:56] time either. So what are my final

[07:58] thoughts? Do I believe if this is going

[08:01] to be the most important anime movie

[08:03] ever? The answer is yes, actually. And

[08:06] let me break down this for you. Why do I

[08:08] believe that this movie is going to be

[08:10] the most important anime movie ever? You

[08:13] know, this movie is more than just hype.

[08:15] We are all excited. We are all hyped.

[08:17] Don't get me wrong. But this is more

[08:18] than just that. This could just be the

[08:21] defining piece of art for anime cinema.

[08:24] If this movie performs well, which I'm

[08:27] pretty sure it will, then this will

[08:28] completely change the anime cinema,

[08:32] people will have a completely different

[08:33] approach towards anime now because this

[08:36] is what's going to tell the people who

[08:38] are non-anime fans or those who do not

[08:40] really like anime that how much

[08:42] impactful can anime truly be. This will

[08:46] completely change the perspective of the

[08:49] world towards anime. This will

[08:51] completely change the perspective of

[08:52] anime haters towards anime. People will

[08:55] be compelled to look what made this

[08:57] movie so great, what made this movie so

[09:00] effective, so successful. And it could

[09:02] also push the shown in anime

[09:04] storytelling to a new standard. If this

[09:06] movie performs well, people will now

[09:09] start to respect anime on a cinematic

[09:12] level. Do you realize what your photo is

[09:15] doing here? They are literally making a

[09:17] trilogy. A trilogy. When Hollywood makes

[09:20] a trilogy, it becomes a franchise. And

[09:23] you photoable just released one movie

[09:26] which is Muggan Train which comes

[09:27] exactly after season 1 and it blew up in

[09:30] the most positive way possible. And now

[09:33] they're making a trilogy. So this just

[09:34] might accelerate new shownen manga anime

[09:38] storytelling into a completely new

[09:40] cinematic age which is every Taku's

[09:42] dream honestly. And I'm I'm so so

[09:44] excited that you Photoable is the one

[09:46] that's doing Demon's Slayer and they and

[09:47] they have decided to end the story in a

[09:50] trilogy. I couldn't be more happier.

[09:52] They couldn't be more uh better decision

[09:55] makers than this. And the movie is about

[09:57] to be released on June 8, July 18th. And

[10:00] one last thing, fans need to be ready

[10:02] for tears, for losses, and for

[10:05] sacrifices because let me tell you once

[10:07] again, this is the most brutal arc of

[10:10] Demon Slayer. This arc will exactly tell

[10:14] you why Demon Slayer is R-rated and why

[10:17] they decided to make it a movie and not

[10:18] just a season. Be ready, I would say,

[10:21] and keep the hype up. Like this video,

[10:23] like it for Demon Slayer Infinity Castle

[10:25] Movie One. That movie is going to blow

[10:27] everyone's mind. Let me say that. Let's

[10:28] get some revenge for Rangokus, shall we?

[10:31] All right, those were my thoughts. Thank

[10:32] you so much for watching. If you watched

[10:34] it till now, I make uh videos every

[10:37] single day. I make a lot of good stuff

[10:39] about anime. You can go to my channel.

[10:41] You can check out other videos too. This

[10:42] is it for today. I will see you tomorrow
