is sane. But we know that you photoable
has decided to make not one, not two,
but three movies to conclude the story.
Going to breaking down step by step what
are the risk factors, what are the
things that we need in the movie. Let's
get into it. So first of all, let's
start with what is even the Infinity
Castle arc? There will not be spoilers.
What is even the Infinity Castle arc?
Okay, one might ask. For those who
haven't read the manga, Infinity Castle
is pretty much like Demon Slayer's
Endgame arc. It's the conclusion and it
is the most brutal arc of Demon Slayer.
Some people think that season 2 was the
best season and I think it's it is the
best, but this is the most brutal season
and the best one in my opinion. And this
is not going to be a season going to be
a movie. This takes place inside the
Infinity Castle. We saw that all of them
fell into Infinity Castle at the end of
season 5. The Hashias are split across
the domain. Everyone is scattered
throughout the infinite domain of
Infinity Castle. So, everyone is in
different spots. No one knows where the
others are. So far, what we do know for
sure, Inoski is alone. Zenitsu is alone.
And by the way, he's locked in. Everyone
fell into Infinity Castle, but he
entered. Guanro, they're both together.
I guess Mitsuri and Canal are fell
together. The mist hasher, the wind
hashifra and the stone hashra they fell
together. At least that's what I think
they felt like. And then obai egro and
mitsuri conroji are both together too.
Now fun thing is that they are inside
the castle. And guys, let me tell you,
you guys are not ready for what's about
to happen. Like I said, this is the most
brutal arc of Demon Slayer ever. And
it's also the conclusion. It's not just
about fighting anymore. Let me tell you,
it's not just about fighting. It's about
sacrifice, legacy, and death. Now, let's
talk about why you photoable chose
movies and not a TV season. I think this
is the the best decision they could
make. And the reason why I think making
movies was a better decision was because
the animation level of Demon Slayer, the
visual level is so god tier that it
actually deserves to be a movie. It's
beyond TV seasons. If you remember
season 2 specifically and pretty much
every season of Demon Slayer when it
ends, when the credits are rolling, they
actually roll it like movie and the
animation is movie level animation. So I
believe that making three movies to
conclude the story is the best decision
they could make. I am in the favor of it
and it actually helps Demon Slayer to
have much wider audience for those
people who still by any chance not know
about Demon Slayer will get to know
about Demon Slayer. Let's break it down
why it wouldn't work as weekly shown in
anime. First of all, let's keep history
in mind because Mugan Train made over
500 million US dollars on the box office
which is crazy. For more than 20 years,
for more than two decades, Haya
Miyazaki's Spirited Away, the famous
anime movie dominated the anime movie
world with it being the highest crossing
anime movie ever made with over $300
million. But the moment Mugan training
came in, it dominated the world of anime
movies again. And this time, not just
breaking the records, but actually
making more records. It grossed over 500
million. So this shows that there is
something about Demon Slayer that
connects with people on a much deeper
level, on a spiritual level even because
people cry. People cry their eyes out at
the end of Mugan Train. That movie is
not only sad, not only emotional, but
also very impactful. It completely
changed the cinema for anime. It build a
new foundation for anime in the world.
It's releasing in July 18. It's
releasing on July 18 in Japan and on
streaming services on Toho and then in
September 18 in USA and Canada. I
believe this would be a perfect chance
for them to dominate the summertime box
office because this movie is going to
make a lot of money. Let me tell you
something and you guys are not ready for
what's about to happen. This is going to
be crazy. For those who have not read
the manga, you have no idea what's
coming for you, buddy. Be ready for
deaths. I'm I'm telling you one thing.
Be ready for deaths. They're going to be
a lot of deaths. There's going to be
sacrifice. There's going to be emotional
turmoil. Be ready. But shit's about to
hit the fan. Let me tell you, it's going
to be amazing. Let's talk about the
emotional and psychological weight of
this arc. And of course, movies, too,
but this arc specifically. There are
some specific hasheras which have some
personal vendetta against uh some upper
moons. Some will experience loss. Some
will experience irreversible growth.
Everyone will be changed after this arc
cuz this is the defining arc. A lot of
things are going to happen in this arc
which people will people will remember
forever. In the future when people will
remember Demon Slayer, they're going to
remember this arc. Whenever the whenever
someone will talk about Demon Slayer,
they will immediately start to remember
the Infinity Castle art. That's how
impactful it's going to be. These are
going to be the defining moments of
Demon Slayer's entire story. Let's
address the elephant in the room, the
euphortable factor, animation beyond
logic. We all know that Euphfordable is
one of the best anime studios ever to
exist. Because Demon Slayer isn't uh the
anime through which they have made their
name. Even before Demon Slayer, they
have made their name through Fate
series. They have dominated the anime
industry by how god tier their animation
is. Now, let's break it down. What can
we expect through the animation? It's
going to be good. You photoable isn't
just animating. They are directing
cinema because it's going to be movie.
So, they won't have to censor a lot of
things which they would have done or
would have to do if it was in weekly
shown anime release. uh because they
would have to sensor a lot of things for
TV streaming and that would that would
just kill the vibe. Other than this,
they're actually using 3D technology in
it too. I'm not talking about CGI. I'm
talking about other 3D spatial
environments inside castle movements.
And each fight has a movie level
choreography because this is not going
to be an anime release. So, they would
have to meet the standards of a movie.
And what's rumored, each movie is
getting above $20 million of budget,
which is insane. $20 million of budget
for every single movie. So there are
three movies. 2x3 is six. So 60 million
of total, 20 million on each movie.
They're going to I cannot even begin to
imagine what craziness are they cooking
even as we speak. And okay, there are
some chances why this could fail. Now,
the chances are very slim because Demon
Slayer is a very popular anime and a
very successful franchise by now, but
there's a slim chance why this could
fail or disappoint fans. Let's break
this down. It's logical that a high
expectation equals high risk. But I'm
pretty sure that high expectation will
be met by high standards of quality. So,
we know you affordable how they are.
They are always ready to give us with
something peak. Now, will the movie
format rush major deaths? They're going
to be a lot of deaths. So, will they
rush some major deaths? If each movie,
if I believe, if each movie is given
about 2 hours and 30 minutes of run
time, if each movie is given at least 2
hours, 20 minutes, 2 hours, 30 minutes
or even just 2 hours, but strong and
even 2 hours, I believe that they could
have some very fine pacing with the
story. So pacing will not be affected at
all. Another question that is raised is
can they handle character depth in three
parts? That's a good question. I think
they can. It's just my opinion, my
belief, and my hope. And I'm I'm sure
they can do it. I'm 95% sure they can do
it because they have not disappointed us
in the past. So there's a very high
chance they will not disappoint us this
time either. So what are my final
thoughts? Do I believe if this is going
to be the most important anime movie
ever? The answer is yes, actually. And
let me break down this for you. Why do I
believe that this movie is going to be
the most important anime movie ever? You
know, this movie is more than just hype.
We are all excited. We are all hyped.
Don't get me wrong. But this is more
than just that. This could just be the
defining piece of art for anime cinema.
If this movie performs well, which I'm
pretty sure it will, then this will
completely change the anime cinema,
people will have a completely different
approach towards anime now because this
is what's going to tell the people who
are non-anime fans or those who do not
really like anime that how much
impactful can anime truly be. This will
completely change the perspective of the
world towards anime. This will
completely change the perspective of
anime haters towards anime. People will
be compelled to look what made this
movie so great, what made this movie so
effective, so successful. And it could
also push the shown in anime
storytelling to a new standard. If this
movie performs well, people will now
start to respect anime on a cinematic
level. Do you realize what your photo is
doing here? They are literally making a
trilogy. A trilogy. When Hollywood makes
a trilogy, it becomes a franchise. And
you photoable just released one movie
which is Muggan Train which comes
exactly after season 1 and it blew up in
the most positive way possible. And now
they're making a trilogy. So this just
might accelerate new shownen manga anime
storytelling into a completely new
cinematic age which is every Taku's
dream honestly. And I'm I'm so so
excited that you Photoable is the one
that's doing Demon's Slayer and they and
they have decided to end the story in a
trilogy. I couldn't be more happier.
They couldn't be more uh better decision
makers than this. And the movie is about
to be released on June 8, July 18th. And
one last thing, fans need to be ready
for tears, for losses, and for
sacrifices because let me tell you once
again, this is the most brutal arc of
Demon Slayer. This arc will exactly tell
you why Demon Slayer is R-rated and why
they decided to make it a movie and not
just a season. Be ready, I would say,
and keep the hype up. Like this video,
like it for Demon Slayer Infinity Castle
Movie One. That movie is going to blow
everyone's mind. Let me say that. Let's
get some revenge for Rangokus, shall we?
All right, those were my thoughts. Thank
you so much for watching. If you watched
it till now, I make uh videos every
single day. I make a lot of good stuff
about anime. You can go to my channel.
You can check out other videos too. This
is it for today. I will see you tomorrow
the next video.
