With just a few hours to go before BTS takes the stage for the final concert of their three-night run in São Paulo, вяαzιℓ, the group is also preparing to wrap up the South αмєяι¢αn leg of their tour, which has lasted nearly a month. Excitement has already taken over the area surrounding Estádio do MorumBIS, even before the concert begins. Lucky fans who secured soundcheck access were seen cheering enthusiastically, singing along to “IDOL” and “MIC Drop” while chanting the members’ names.

Several photos and clips shared after the soundcheck have also been circulating on social media, attracting considerable attention.

One photo, in particular, captures the backstage area on one side of the stage, featuring lighting rigs, transparent plastic curtains, and various pieces of technical equipment. What particularly caught fans’ attention was a person standing in front of the area wearing a black hoo∂ιє and a shiny green alien mask. Facing them was another person wearing a shirt with the words “What you need, twin?” Both were wearing headsets and carrying walkie-talkies, leading fans to recognize them as BIGHIT MUSIC staff members.

Another photo received similar attention, showing a staff member wearing a pumpkin-orange shirt with deliberately distressed details that evoked a Halloween costume.

That’s not all. In several other videos and photos captured during the soundcheck, a group of BTS staff members were seen dressed up in amusing costumes. One staff member was dressed as a ρσℓι¢є officer, complete with a fake mustache and a ρσℓι¢є hat; another wore an orange outfit resembling a bee; one sported a denim pirate-style outfit; and another wore a transparent plastic costume paired with a blue hat, among other quirky looks.

Since BTS’s final вяαzιℓ concert falls on October 31, Halloween, fans have begun speculating that the staff—and possibly the members themselves—have prepared special costumes for the occasion. The backstage crew’s spontaneous and creative ideas have left ARMY laughing and giving them a thumbs-up for fully embracing the festive spirit while carrying out their duties.

Meanwhile, during the ending ment at the October 30 concert, Jungkook hinted at a special performance he was preparing for fans on October 31. At the time, fans speculated that he might dress up as a character, with Spider-Man being one possibility. One fan even thought of a character with a particularly strong connection to Jungkook: David Martinez from Cyberpunk: Edgerunners.

These theories seem all the more plausible given BTS’s history of memorable Halloween costumes prepared for their fans. In 2014, the members dressed up as characters including Dracula, Jack Sparrow, Chucky, the Joker, and the Grim Reaper for their “War of Hormone” dance practice video. In 2017, BTS delighted fans once again by portraying Snow Wнιтe and the Seven Dwarfs in their “Go Go” Halloween dance practice video, with V taking on the role of Snow Wнιтe.

With these backstage clues, Jungkook’s mysterious hint, and the group’s creative Halloween tradition, ARMY are eagerly anticipating a special stage in вяαzιℓ. Will BTS really surprise fans with an υиєχρє¢тє∂ costume concept to bring the South αмєяι¢αn leg of their tour to an unforgettable close? Excitement among fans is reaching a fever pitch:

- oh my god, the bts team is wearing halloween costumes, this mean bts will wear costumes too

- Today is gonna be αωєsome, they should've livestreamed this concert. I'm already αѕѕuming they're gonna wear costumes.

- Some of the staff members are wearing Halloween costumes today, so hopefully the boys will come out in costume too!

- The BTS staff are just as chaotic as the members. Why is everyone so funny?! I can't wait to see what BTS have prepared for tonight!

- Not the staff going all out with their Halloween costumes. They're really committed to the vibe! This concert is already iconic!

- If the staff are already this funny, imagine what BTS have in store for us. Jungkook said we should look forward to tonight, and now I'm even more excited

- This is so random and so funny. BTS staff turning the soundcheck into a Halloween party before the show even starts! вяαzιℓ ARMY, you're in for soмєтнing special

- Tonight, вяαzιℓ gets BTS… and the rest of us just get ghosts, goblins, and a little FOMO. Honestly, I’m trying to decide if the loudest screams tonight will be from the Halloween ghosts or the вяαzιℓian ARMYs!
