MAPPA’s 15th Anniversary Event Could Change Anime Forever
Mark your calendars, anime fans. June 19, 2026, is about to become one of the most significant dates in recent anime history. MAPPA Studio, the powerhouse behind some of the biggest anime of the decade, is hosting a massive 15th Anniversary Event — and the rumor mill is spinning out of control.
What makes this event so special? MAPPA has confirmed they’ll be sharing updates on six major titles, and the lineup reads like a who’s who of modern anime: Jujutsu Kaisen Season 4, Chainsaw Man’s Assassins Arc, Attack on Titan continuation, and more. If even half the speculation proves true, we’re looking at announcements that could dominate social media for weeks.
Jujutsu Kaisen Season 4: The Culling Game Continues
Let’s start with the elephant in the room: Jujutsu Kaisen Season 4. After Season 3 wrapped up in March 2026, fans have been hungry for news about the next chapter. The Culling Game Part 2 was officially confirmed back in March, but details have been scarce.
What we know so far:
- Season 4 will continue the Culling Game arc, one of the manga’s most intense storylines
- Yuji’s English voice actor Adam McArthur teased updates back in May
- MAPPA held a major stage event on June 14 that hinted at the June 19 reveal
- The arc features high-stakes battles, complex strategies, and major character deaths
Fans are expecting a release date announcement, a full trailer, and possibly key visual reveals. Some optimistic viewers are even hoping for a surprise release window of late 2026 or early 2027.
Chainsaw Man Assassins Arc: Denji’s Darkest Chapter Yet
If you thought Chainsaw Man Season 1 was wild, buckle up. The Assassins Arc (also known as the International Assassins Arc) is widely considered one of the manga’s darkest and most emotionally devastating storylines.
Without spoiling too much for anime-only fans, this arc features:
- International devil hunters targeting Denji
- Major character deaths that shocked manga readers
- Makima’s true nature becoming clearer
- Some of the most brutal action sequences in the entire series
The big question: Will MAPPA announce a theatrical release or go straight to a Season 2 format? Given the success of Demon Slayer’s movie approach and the arc’s cinematic scope, either option is on the table.
Attack on Titan: Is There More Story to Tell?
Wait — didn’t Attack on Titan end? Technically, yes. The Final Season Part 3 concluded the main story in 2023. But rumors have persisted about additional content, potentially covering the extra pages from the manga’s final volume or even exploring new territory.
Other theories include:
- A compilation film for international theatrical release
- An OVA series filling in backstory gaps
- A spin-off focused on side characters
- High-quality Blu-ray box set announcement
MAPPA hasn’t confirmed what the “Attack on Titan update” entails, which has only fueled speculation. Some fans think it could be related to the upcoming live-action adaptation, but that seems unlikely given MAPPA’s focus on animation.
Three More Mystery Titles
Here’s where things get really interesting. MAPPA confirmed six titles total, but only three have been named publicly. What are the other three?
Popular theories include:
- Hell’s Paradise Season 2 — The first season ended on a cliffhanger in 2023
- Vinland Saga Season 3 — Season 2 wrapped in 2023 to critical acclaim
- Kakegurui Season 3 — The gambling anime has a dedicated fanbase
- A completely new original project — MAPPA has hinted at original works in development
- Dororo continuation — Fans have been begging for more since 2019
The lack of official information has sparked endless Reddit threads and Twitter debates. Whatever MAPPA reveals, it’s guaranteed to trend worldwide.
Why This Event Matters So Much
MAPPA has become the defining anime studio of the 2020s. They took over Attack on Titan’s final season from Wit Studio, delivered the stunning Chainsaw Man adaptation, and carried Jujutsu Kaisen to global phenomenon status. Their animation quality, especially in action sequences, is consistently industry-leading.
But the studio has also faced criticism for allegedly overworking animators and taking on too many projects simultaneously. This anniversary event is MAPPA’s chance to prove they can balance quality with quantity while treating their staff better — a promise they’ve made repeatedly in recent interviews.
The timing is also perfect. Summer 2026 is shaping up to be one of the biggest anime seasons in years, with Demon Slayer: Infinity Castle Part 2, Blue Lock Season 3, and multiple high-profile premieres. If MAPPA drops major announcements now, they’ll dominate the conversation heading into fall.
How to Watch the Event
MAPPA hasn’t announced full streaming details yet, but based on past events, expect:
- Live stream on MAPPA’s official YouTube channel
- Simultaneous streams with English subtitles
- Event start time around 7:00 PM JST (10:00 AM UTC, 6:00 AM ET)
- Archived footage available afterward for those who miss it live
Set your alarms now. Given the hype around this event, servers might struggle with traffic, so logging in early is recommended.

The June 19 MAPPA event is shaping up to be one of the biggest anime announcements of 2026. Will Jujutsu Kaisen Season 4 get a 2026 release date? Will Chainsaw Man go theatrical? What are the three mystery titles?
