Anime Convention Chaos: Yuji Itadori Cosplayer Arrested After Amos Yee Altercation in Singapore

The internet is once again proving that reality is somehow stranger than fiction.

A shocking incident outside the Doujin Market anime convention in Singapore has gone massively viral after videos showed a teenager dressed as Yuji Itadori from Jujutsu Kaisen allegedly assaulting controversial blogger Amos Yee.

Now social media is completely divided, and the story has exploded across TikTok, X, Reddit, and YouTube.

What Happened?

On May 9, 2026, outside the Suntec Singapore Convention and Exhibition Centre, videos began circulating online showing an 18-year-old cosplayer attacking Amos Yee during a public confrontation.

The teenager, later identified as Bosco Chun Ho Wang, was reportedly dressed as Yuji Itadori, the main character from the hugely popular anime and manga series Jujutsu Kaisen.

Clips spreading online appeared to show:

• punches,

• kicks,

• and stomping during the altercation.

Amos Yee later posted images online showing injuries, including a bloodied lip.

Singapore police later arrested the teenager, who was subsequently charged with:

• voluntarily causing hurt,

• and public nuisance.

Why Is This Story So Viral?

This story exploded online for several reasons.

First, Amos Yee has remained one of the most controversial internet personalities connected to Singapore. His criminal convictions in the United States involving child-related offenses made him a highly disliked figure online.

Second, the fact that the incident involved:

• anime cosplay,

• a major convention,

• viral videos,

• and Jujutsu Kaisen

made it instantly spread across social media platforms.

Many users described the situation as feeling “unreal” or “straight out of an anime.”

The Online Debate

The internet reaction has been extremely divided.

Some users strongly condemned the attack, arguing that:

• violence is never acceptable,

• and nobody should take the law into their own hands.

Others defended the teenager, claiming the incident was an example of “street justice” because of Yee’s criminal history.

The debate intensified after the teenager allegedly claimed online that he believed he was intervening to protect another attendee from inappropriate behavior.

However, those claims were not immediately verified by police at the time the videos spread online.

Doujin Market and Convention Safety

Reports also stated that organizers of the Doujin Market convention had already banned Amos Yee from the event due to safety concerns.

That detail sparked even more discussion online about:

• convention security,

• public safety,

• and how quickly internet outrage can spill into real life.

Anime conventions have become bigger than ever in recent years, attracting thousands of attendees, cosplayers, influencers, and content creators. But viral incidents like this also show how social media attention can rapidly turn public events into chaotic situations.

Social Media’s Role

One major reason this incident spread so fast is because of how internet culture works today.

The moment videos appeared online:

• TikTok clips exploded,

• reaction videos flooded YouTube,

• memes spread across X and Reddit,

• and people instantly chose sides.

Many users criticized how quickly social media users turned a serious real-world incident into entertainment content.

Others pointed out how fandom culture and viral trends can sometimes blur the line between online behavior and real-life consequences.

Final Thoughts

Regardless of public opinion surrounding Amos Yee, the situation has become a reminder that real-world violence carries serious legal consequences.

At the same time, the bizarre combination of:

• anime cosplay,

• convention drama,

• internet controversy,

• and viral social media reactions

turned this into one of the most talked-about internet stories of 2026.

And honestly, “Yuji Itadori cosplayer arrested after anime convention altercation” sounds more like a chaotic anime plot than an actual headline — but somehow, it’s real.
