Executed by performing two quarter-circle forward motions and pressing kick, Zeku performs a backflip, kicking his opponent during the rotation. If the initial attack connects, he kicks his opponent into the air. After landing on the ground, he leaps toward his opponent as the background changes from the current stage to a white, foggy forest-like scene. Zeku then proceeds to rapidly attack his opponent from all directions while changing between his old and young form for each hit:
- A dive kick to the midsection.
- A punch to the back.
- A knee strike to the chest.
- A chop to the back.
- A kick to the stomach.
The fifth attack launches the opponent, which allows Zeku to dash toward his opponent and deliver three high-speed attacks as he passes them. After the third hit, he finishes the move by slamming his opponent into the ground with his feet. Zeku then cartwheels off of his opponent, spins and poses before dropping back to his stance.
Like most Critical Arts, this move is used to end combos to deal large amounts of damage to the opponent. The Batsuzan Gaisei can be cancelled from Zeku's special moves such as Bushin Gram - Koku or Bushin Sho. Zeku is also completely invincible during startup and active frames of this attack. The range of his Critical Art covers about 1/4 of the screen, making this a decent tool to use for whiff punishing. It can also be used as an anti-air attack. This move can also be used in both forms. Also, Zeku retains his current form after Batsuzan Gaisei is performed. Regardless of his form, the damage of this move is the same.
