Unfortunately, " Dungeon ∞ Spiral ", an interactive attraction facility on the 4th floor of Tokyu Kabukicho Tower in Tokyo, will close on February 28, 2026 (Sat), but from February 11 (Wed) to 28 (Sat), 2026 (Wed), a collaboration project with the TV anime & "quot;Gnosis" will be held as a finale project. A collaboration project with "quot;Gnosia " is being held from February 11 (Wed.) to 28 (Sat.), 2026! Influencer and YouTuber Fujii 4-dan has actually experienced it!
Dungeon ∞ Spiral" and TV anime "Gnosia" are collaborating!
グノーシア×ダンジョン∞スパイラル特設ページYou are on board the spaceship D.Q.O.. Among the 15 crew members, there are two "Gnosia" who are hiding their true identities. You must gain the trust of the crew by playing games in the ship's activity facilities, and then expose the Gnosia by voting for them. But all you can do is play the physical games. Have a nice trip.
So, starting Wednesday, February 11, 2026, the "Dungeon ∞ Spiral" will change to Gnosia's specifications!
You can enjoy a different experience from the usual "Dungeon ∞Spiral".
The person who will challenge "Dungeon ∞Spiral" is an influencer and YouTuber Fujii 4dan (@MTNRFG ).
First, let's listen to the explanation.
*The following screenshots are as of the time of the interview, and some specifications may change in the future.
The TV anime "Gnosia" is a sci-fi loop mystery based on a video game about werewolf games. Fujii 4dan challenges various attractions as a crew member of the spaceship D.Q.O.
Saiga NAKThe spaceship D.Q.O. has 15 other crew members, two of whom are infected with Gnosia. The Gnosia infected people attack humans at night, so we must be the first to cold sleep the infected to prevent the spread of the disease.
Gain the trust of other crew members by defeating the bosses that appear in the "Dungeon ∞ Spiral." The more cold sleep votes you have, the more chance you have of cold sleeping a Gnosia infected person.
After setting up your personal avatar and team name, you are ready to go!
We'll start with the individual competition.
The first is the individual game, in which one player challenges a randomly selected puzzle. This time we had a special multiple experience.
The "Cup of Sparks" where you have to put the pieces back together after they fall apart.
Fujii 4dan: "It seems to require a good grasp of space. As a former science major, I can do this kind of puzzle..."
Fujii 4dan: "That one."
Fujii 4dan "Huh? "
Fujii 4dan: "Huh..."
Fujii 4dan's playing seemed to be marked by many mistakes, but he managed to get an A rating. At least he got off to a good start.
The next challenge was the "Arrow of Wisdom," in which you pull the ball with your finger to collect medals.
Fujii 4dan: "It's like billiards, right? I'll take care of it."
The key is to use the wall well to collect medals...
Fujii 4dan: "Oh no. The wall is too big."
Fujii 4dan: "I'm starting to see the medals I just can't get as units..."
Fujii 4dan: "B is safe! "
Panels of each character appeared in the facility during the collaboration period! Fujii 4dan also took a snapshot to commemorate the event.
After completing the three puzzles, you can move on to the next one. To succeed in the cold sleep of the Gnosia infected, earn the trust of the crew by playing an active role in the attraction!
Collect votes in cooperative attractions!
Now, here's the best part.
After finishing the puzzle, which was an individual game, the next step is for two or three players to cooperate to conquer the three designated games.
The first game is "The Cave." One player turns the handle to adjust the speed of the trolley, while the rest of the players hit the ball at the enemies.
Played under the watchful eye of Gina and SQ.
Fujii 4dan, who used to play tennis, had very good control...
He succeeded in defeating the boss!
Fujii 4dan: "A human being becomes stronger by the number of mistakes he makes."
Gina and the others recognized me and gave me the right to vote! Keep up the good work...
Fujii 4dan: "I'm so tired."
You can bring your own drinks with lids, so don't forget to hydrate yourself properly! The second attraction is "Wilderness," where one player turns a handle to load shells and the rest pull ropes to hit the enemy.
Fujii 4-dan is a strong opponent, and he is determined to get rid of his daily frustrations.
Fujii 4dan: "This is so hard that I have to laugh..."
Fujii 4dan: "Foolishly, you say! "
The third attraction is an "altar" where one player performs a nervous breakdown and the remaining players assemble a large puzzle. Can you make use of the brains you have?
Easy at first, but ...
Defeating bosses is not a simple task.
Still, we managed to struggle and...
Saiga NAKFujii 4dan: "Did I show my science-like nature?"
Rachio and Lemnan also recognized Fujii 4dan's success.
Fujii 4dan: "I heard you exercise, but I didn't know it was this intense..."
The final challenge, with Setsu watching over him!
The last attraction was "Erebos," a game in which you defeat enemies by touching them one after another.
The attraction uses all four sides of the room, so you need to communicate with your friends to defeat the boss.
I didn't completely defeat the boss, but I did surprisingly well.
Setsu also praised me.
Fujii 4dan: "If you do it, you can do it. If you do it. "
Who is the GNOSIA?
With your earned voting rights in hand, head to the polling place.
Voting begins! In the animated TV series "Gnosia" we will be discussing and identifying those infected with Gnosia, but since it's the first day, we don't have a clue.
Sorry to all of you, but we have selected 5 people on a hunch! You will be cold sleeping.
The result is...
Unfortunately, there still seems to be a Gnosia infected person on board.
And both of them!
Setu "got it? "
Fujii 4dan: "No, I don't get it! "
Players will receive playing card-style cards (15 in all) as a bonus for playing! In addition, players who are able to identify the Gnosia infectees will also receive up to two additional cards!
Players who succeed in cold sleeping two Gnosia infectees will be given the right to challenge Hard Mode, where they will be able to cold sleep two Gnosia infectees. If you successfully identify the two Gnosia infectees, you will receive an original QUO card!
The video of the voting booth is actually broadcast live to the entrance of the "Dungeon ∞ Spiral". If you watch the votes of other participants, you can get a hint to identify the Gnosia infected person....
Digital photo service will be available as a souvenir!
As an added bonus, you will be able to experience a digital photo service. Take photos with characters who may be Gnosia-infected!
Fujii 4-dan also experienced it!
When you read the 2D code printed on the receipt...
It was a grand failure.
...but what a surprise! You can experience it as many times as you want, only when there is no one waiting! Friendly even for a ditz like Fujii 4dan.
If there is someone waiting, please take over one time!
As mentioned earlier, there are many photo spots in the "Dungeon-Infinity Spiral. A must-see for "Gnosia" fans!
In addition to the "Dungeon ∞ Spiral" and the "Gnosia" TV anime, you can purchase a player selection screen-style acrylic stand (15 kinds in total) exclusively for those who have played the "Dungeon ∞ Spiral" x "Gnosia" TV anime.
At the time of writing, acrylic stands of some characters such as "Jina," "Remnan," and "Setsu" are sold out. The number of original QUO cards has also reached the planned distribution limit. However, the management is ...
- Player selection screen-style acrylic stand (15 kinds in total): orders will be taken online.
- Original QUO cards: to be redistributed after February 14, 2026 (Saturday)
In response to the great response, the company has announced the following For the latest information, please visit "Dungeon ∞ Spiral" Official X (@thetokyomatrix ).

Interview with Manager Matsudaira
- How did you come up with the idea for this collaboration?
Matsudaira: Since this facility is managed by the Sony Music Group, I had been watching the anime that Aniplex handled. Among them, "Gnosia" is set on a spaceship, and the atmosphere, including the slightly cyber atmosphere, seemed to fit perfectly! I thought "Gnosia" was a perfect fit. So I approached the producer of the "Gnosia" TV anime and this collaboration was born. Even Yuri's clothes are in Danspa colors (laughs).
- There was also a voice for the new video.
Matsudaira: Setsu and LeVi were completely new, and we asked Ikumi Hasegawa and Saori Hayami to do the long version.
- LeVi's announcement was so natural that I thought, "Was it always like that? It was so natural!"
Matsudaira: The atmosphere really fits perfectly. Ms. Saori Hayami also gave a perfect performance, as if she understood everything.
- The tug-of-war attraction "Wilderness" was the hardest part.
Matsudaira: It was hard work (laughs). We created it to create a realistic experience of pulling it as hard as you can and sending a shell off into the distance.
- The attractions you experienced this time were only a small part of the experience, weren't they?
Matsudaira: That's right. The attractions are chosen at random each time, and they include jumping to the rhythm, pedaling a bike machine, and seriously dashing a distance of more than 20 meters.... You can really get a good workout here alone.
- Any final message?
Matsudaira: "Dungeon ∞ Spiral" has been operated as a one-of-a-kind attraction where you can have a great adventure with your friends and family in the heart of the city. Unfortunately, it will close at the end of February, but we hope that you will take this opportunity to fully enjoy the world of "Gnosia" and our collaboration.
