A Frieren: Beyond Journey’s End cosplayer leapt into action to extinguish a fire after a blaze broke out at a shopping mall in Vietnam.

Cosplayers aren’t exactly the type of people you’d expect to take action in serious situations, but one man is challenging those conceptions.

On January 25, a cosplayer named Tuấn Dũng was dressed up as Himmel from Frieren for an event at a shopping mall.

Suddenly, a stage light reportedly overheated, starting a fire. Luckily, Dũng wasted no time and took swift action, even before the event staff or mall personnel could.

In footage posted to social media and shared by the Himmel cosplayer, Dũng grabbed a fire extinguisher and proceeded to put out the blaze.

Video shows the cosplayer aiming the fire extinguisher at the burning light and letting rip as others watched in amazement. He then started helping shoppers and attendees by moving their carts out of the area.

On Facebook, he explained the situation and why he took action writing, “Near the stage, there was a fire near the spotlights. Seeing this, I applied my fire safety knowledge to handle the situation and prevent the fire from spreading.”

“This shows that everyone needs knowledge of fire safety to be able to handle unexpected situations like this.”

Fans were impressed with the cosplayer’s skills as the footage spread across anime communities.

“Himmel would do the same,” one top commenter said.

“It’s paramount that if you cosplay Himmel, you must act heroic,” another chimed in.

This is a welcome change from some other viral cosplayer incidents that have happened lately. Last year, cosplay influencer Kit Noel was arrested after allegedly threatening to plant a bomb at a Texas anime convention during a feud over an energy drink brand.

In another wild incident, police officers in Melbourne rushed to a shopping center after reports of a knife-wielding man turned out to be a Demon Slayer fan in cosplay.

A cosplayer in Toronto was handcuffed and detained after walking through a park for a cosplay event with a replica rifle.

Toronto was hosting its first Anime Connects Cherry Blossom Picnic at Trinity-Bellwoods Park on May 3, with many cosplayers showing up for the event.

Things got out of hand quickly, however, when a man dressed as a mercenary from the S.T.A.L.K.E.R series showed up in full tactical gear and a replica rifle.

Footage quickly went viral, with numerous police showing up and their sirens blaring after receiving calls that someone was roaming the area with a firearm.

Video shared by journalist Caryma Sa’d and others showed the police approaching the cosplayer, who quickly surrendered and cooperated.

After being told to get on his knees, the cops took the man to the ground, handcuffed him, and escorted him to a police cruiser.

According to people in the park, the cosplayer had been warned not to carry a replica rifle, but ignored their concerns. Still, many voiced displeasure with the overwhelming police presence.

“Poor guy,” one said. “This is insane. All for a friggin’ costume.”

Luckily, the authorities were understanding and the man was released without charges, even shaking hands with the police sergeant in the aftermath.

Speaking to the Toronto Sun, the cosplayer said, “I have been cosplaying in Toronto with similar setups for five years with absolutely no issues, so you can see why I felt comfortable coming out to the event. I’ve even gone to similar events in that exact park in the past.”

“There were other cosplayers with life-like weapons and equipment too, so it is not out of the ordinary, and there were some present that day aside from myself.”

The cosplayer further noted that while he typically has bright orange tape on his weapons, he momentarily took it off for a picture, and that’s when the police arrived.

Cosplays have caused major police reactions before. Last August, a 16-year-old Resident Evil cosplayer in the UK was taken in by police after being mistaken for a criminal due to carrying an imitation firearm.

Across the globe in Australia, officers in Melbourne rushed to a shopping center after reports of a knife-wielding man turned out to be a Demon Slayer fan in cosplay.
