After nearly a year of dominating theaters around the world, Demon Slayer: Kimetsu no Yaiba – Infinity Castle is finally making its way to streaming. The film arrives on digital platforms and Crunchyroll on July 28, giving fans another chance to experience the opening chapter of the franchise's ambitious movie trilogy from home.
While the streaming announcement grabbed most of the attention, eagle-eyed fans noticed a much smaller change that could prove even more important, according to ComicBook. Promotional artwork for the film now includes a Roman numeral "I" in the title, a subtle update that officially identifies the movie as the trilogy's first installment and suggests that marketing for Part 2 is finally beginning to ramp up.
The Updated Infinity Castle Logo Quietly Prepares Fans For The Trilogy's Next Chapter
When Infinity Castle first premiered in Japanese theaters, the movie was promoted as "Part 1 – Akaza Returns." International audiences, however, largely saw the film marketed simply as Infinity Castle, with little emphasis on it being the opening entry in a three-film finale. That approach helped keep the spotlight on the standalone theatrical release.
The new digital and streaming artwork changes that. By adding the Roman numeral "I" to the title, the franchise is standardizing its branding worldwide. Although the adjustment appears minor, it creates a clear framework for future films to be labeled as Parts II and III, making the trilogy structure much more obvious for global audiences.

01
The series follows a young charcoal seller whose family is slaughtered by a demon. Only his sister Nezuko survives — turned into a demon herself. What is the protagonist’s full family name?
✓ Correct! Tanjiro Kamado is the eldest son of the Kamado family of charcoal-makers. The Kamado name, written with characters meaning “furnace,” is a subtle nod to the family’s ancient connection to fire and Sun Breathing — the original breathing style all others descend from.
✗ Demon deception! The answer is Kamado. Agatsuma is Zenitsu’s surname, Tomioka is the Water Hashira Giyu’s, and Hashibira belongs to the boar-headed Inosuke. Tanjiro Kamado’s family lived high in the mountains as charcoal-burners — a lineage that secretly carried the art of Sun Breathing.
02
Demon Slayer: Kimetsu no Yaiba began as a serialized manga in Weekly Shonen Jump in 2016 before becoming a global anime phenomenon. Which mangaka created it?
✓ Correct! Koyoharu Gotouge is famously private — the pen name gives no indication of gender, and the author has consistently declined interviews and public appearances. The manga ran for 205 chapters from 2016 to 2020 and sold over 150 million copies, making it one of the best-selling manga of all time.
✗ Demon deception! The answer is Koyoharu Gotouge. Hajime Isayama created Attack on Titan, Eiichiro Oda writes One Piece, and Masashi Kishimoto created Naruto. Gotouge wrapped Demon Slayer’s main story in 2020 after just four years — a surprisingly short run for a series of that scale.
03
Before the Final Selection, Tanjiro trains for two years on Mount Sagiri under former Hashira Sakonji Urokodaki. Which breathing style does Urokodaki teach him?
✓ Correct! Water Breathing has ten forms plus the Eleventh Form (Dead Calm), the last of which was created by Urokodaki’s finest student, Giyu Tomioka. Tanjiro later combines Water Breathing with his family’s ancestral Hinokami Kagura (Sun Breathing), which proves far more powerful against high-ranking demons.
✗ Demon deception! The answer is Water Breathing. Thunder Breathing is Zenitsu’s style, Flame Breathing is the Rengoku family’s specialty, and Stone Breathing belongs to Gyomei Himejima. Urokodaki was the Water Hashira decades before Giyu, and his pupil Tanjiro eventually surpasses him by unlocking Sun Breathing.
04
Nezuko Kamado is the only known demon allowed to travel with the Demon Slayer Corps — she wears a bamboo muzzle and is carried in a sealed wooden box by day. What makes her so uniquely valuable to her brother’s cause?
✓ Correct! Nezuko restores her body and power by sleeping, bypassing the need to consume humans that defines every other demon. Her unbroken love for her brother — and her implanted suggestion from Urokodaki that all humans are her family — anchors her humanity. She does eventually gain sunlight immunity, but that’s a much later plot twist.
✗ Demon deception! The answer is that she sleeps instead of feeding on humans. Nezuko can change her size (true but minor) and eventually gains immunity to sunlight (near the end of the series), but her defining trait is that she refuses to eat humans — sustaining herself through long periods of sleep instead.
05
The series’ ultimate antagonist is the original demon — a creature who has walked the earth for over a thousand years, creating every other demon from his own blood. What is his name?
✓ Correct! Muzan Kibutsuji is the Demon King — created accidentally by a Heian-era doctor whose medicine overcame his terminal illness but turned him into an immortal monster. His lifelong obsession is curing his sunlight weakness. Akaza, Douma, and Kokushibo are all Upper Moon demons under his command — terrifying but all creations of Muzan himself.
✗ Demon deception! The answer is Muzan Kibutsuji. Akaza (Upper Moon 3), Douma (Upper Moon 2), and Kokushibo (Upper Moon 1) are all fearsome Twelve Kizuki, but they’re Muzan’s creations — not the original demon. Muzan is the source of every demon in the story, and destroying him ends the demon curse forever.
06
The Mugen Train arc features Tanjiro being mentored by the cheerfully boisterous Flame Hashira — a man whose final words (“set your heart ablaze”) became a fandom rallying cry. What is his name?
✓ Correct! Kyojuro Rengoku — the Flame Hashira with the iconic yellow-and-red flame-haori and the signature “UMAI!” catchphrase — battles Upper Moon 3 Akaza in one of the series’ most devastating fights. His death and final speech to Tanjiro became one of the most emotionally impactful moments in modern anime.
✗ Demon deception! The answer is Kyojuro Rengoku. Giyu Tomioka is the Water Hashira (the stoic one who saves Tanjiro and Nezuko in episode 1), Tengen Uzui is the flamboyant Sound Hashira from the Entertainment District arc, and Gyomei Himejima is the gentle-giant Stone Hashira — the Corps’ strongest.
07
Demon Slayers wield Nichirin Blades — color-changing katanas forged from sun-infused ore. When a slayer first draws theirs, the blade takes on a color reflecting their breathing style. What color does Tanjiro’s blade turn?
✓ Correct! Tanjiro’s blade turns black — an extremely rare color associated in-universe with bad omens and the superstition that black-blade wielders don’t live long. The real reason, revealed later, is that black blades resonate with Sun Breathing, the original breathing style from which all others descend.
✗ Demon deception! The answer is black. Water Breathing typically produces blue (like Giyu’s), Mist Breathing produces a pale greenish-white, and Flame Breathing a vivid red-orange. Tanjiro’s pitch-black blade is considered unlucky — but it’s actually the mark of a Sun Breathing user, the rarest and most powerful style of all.
08
The 2020 anime film Demon Slayer: Mugen Train became a worldwide box-office phenomenon despite releasing in the middle of the pandemic. What record did it famously break in Japan?
✓ Correct! Mugen Train dethroned Hayao Miyazaki’s Spirited Away, which had held the Japanese box-office record for 19 years. Ufotable’s breathtaking animation of the Tanjiro-versus-Akaza battle, paired with Rengoku’s emotional farewell, turned a theatrical arc of the anime into the highest-grossing film in Japanese history.
✗ Demon deception! The answer is that it surpassed Spirited Away as Japan’s highest-grossing film ever. Mugen Train didn’t win an Oscar (though it was eligible) and hasn’t crossed $1 billion globally. But in Japan, it dethroned Miyazaki’s 2001 classic — a record many thought would stand forever.

Hashira-level expert — or still at Mizunoto?
The timing also makes sense. The first movie enjoyed an exceptionally long theatrical run in Japan, remaining in cinemas for roughly nine months while becoming one of the country's biggest box office successes. With that run now ending and the July 28 streaming release for Infinity Castle approaching, the studio can shift its full attention toward promoting the sequel rather than continuing to market the first film.
Why Fans May Finally Get Their First Look At Infinity Castle Part 2

Despite the updated branding, Demon Slayer: Kimetsu no Yaiba – Infinity Castle Part 2 still has no official release date. However, the revised logo suggests that the promotional cycle is finally entering its next phase. Once the first film becomes widely available through streaming and home media, expectations naturally turn toward what's next for Tanjiro and the Demon Slayer Corps.
Earlier this year, animation studio ufotable included Infinity Castle Part 2 among its officially announced future projects during a presentation outlining upcoming productions. At the same time, the studio confirmed that its adaptation of Witch on the Holy Night remains a major priority, making a 2026 theatrical release for the second Infinity Castle film increasingly unlikely.

Demon Slayer hosted the first part of the concluding film trilogy last year, and the end of the series isn't quite here yet, with a surprise release
Instead, 2027 now appears to be the earliest realistic launch window. Even so, fans may not have to wait that long for meaningful news. A teaser trailer, key visual, or release announcement before the end of 2026 would be met with a lot of excitement. After spending nearly a year celebrating the first movie's theatrical success, the series finally seems ready to move the spotlight toward its highly anticipated second chapter.
For now, the Roman numeral added to Infinity Castle may seem like a tiny design tweak. Yet in blockbuster franchises, these subtle branding changes often signal much larger marketing plans behind the scenes. With the first film finally reaching streaming audiences worldwide on July 28, the path is now clear for Demon Slayer: Infinity Castle to begin its next major promotional campaign, and for fans to get their first real glimpse of the trilogy's explosive continuation.
