Shibuya Tube Simulations Explained: What They Are and What You Do in One

Quick answer

Tube Simulations are Shibuya [Beta]'s virtual combat activities: you enter one and fight, testing your fighting skills while you work toward progressing through the sorcerer grades.

• Inside one, you fight with Shibuya's standard combat controls — attacks, criticals, dashes, blocks, parries and cursed energy infusion.

What Tube Simulations are

Tube Simulations are Shibuya [Beta]'s virtual combat activity. The official game description folds them straight into the game's core loop: climb the sorcerer grades, earn cursed techniques through hard trials, contain curses instead of exorcising them — and “fight in virtual Tube Simulations.” They are the game's simulated battles: fights you step into as a sorcerer.

The setting around them matters for why they exist. Shibuya [Beta] is a Jujutsu Kaisen-inspired fighting game set 1,000 years after the original story, built by the Roblox group Project Mᅠ. You develop your sorcerer by climbing the grades, earning cursed techniques through hard trials, and containing curses rather than exorcising them. The game also leans hardcore: the official description warns that the stronger you get, the more a careless death can cost you, so fighting skill carries real weight (see death penalties).

One caveat before you dive in: Shibuya [Beta] is still in its early stages, and the developer notes that things are subject to change and improvement. Treat these details as current for the beta, and expect systems — including the simulations — to keep evolving.

What you do in a Tube Simulation

You fight. That's the activity: the game advertises fighting in virtual Tube Simulations, and entering one is a chance to test your fighting skills in actual combat.

Those fights run on Shibuya's regular combat system. Its advertised combat controls — general inputs for any fight in the game, not simulation-specific mechanics — cover offense, defense, mobility and cursed energy:

Data table

Input

L

What it does

Equip your weapon

Input

M1

What it does

Attack

Input

M2 or R

What it does

Critical attack

Input

Q

What it does

Dash; hold Q to lunge

Input

F

What it does

Block; tap F right before a hit to parry

Input

E

What it does

Infuse your attacks with cursed energy

Input

X

What it does

Uppercut; press X again for rushdown

Input

B

What it does

Grip NPCs or players

Input

V

What it does

Carry NPCs, players or objects

Data table

Input	What it does
L	Equip your weapon
M1	Attack
M2 or R	Critical attack
Q	Dash; hold Q to lunge
F	Block; tap F right before a hit to parry
E	Infuse your attacks with cursed energy
X	Uppercut; press X again for rushdown
B	Grip NPCs or players
V	Carry NPCs, players or objects

A few of those inputs reward practice. The parry window is a tap of F right before a hit lands, holding Q instead of tapping it turns your dash into a lunge, and E layers cursed energy onto your attacks. The complete input list lives in our Shibuya controls guide, and the combat guide goes deeper on the fighting system itself.

How Tube Simulations fit into sorcerer grade progression

Grades are Shibuya's advancement ladder — the official description tells you to climb the sorcerer grades, and our sorcerer grades guide breaks that ladder down. Tube Simulations plug directly into the climb: you can enter one to test your fighting skills and progress through the grades.

Testing is the operative word. Your sorcerer's development comes from several directions at once — hard trials that earn cursed techniques, and curse containment instead of plain exorcism. Tube Simulations are the piece of that loop where you put your fighting to the test and push your grade forward, which matters in a game where the description itself pairs the grade climb with a warning: the stronger you get, the more a careless death can cost you.

Where Tube Simulations sit in your run

If you're just starting your sorcerer, the beginner guide and progression guide cover the broader route — grades, trials, containment and combat — that Tube Simulations plug into. Fight, test yourself, and climb.
