Explosive Bubble Prison

Using her Explosive Bubble Technique, Atsuko creates a bubble around an opponent, that acts as a sort of prison. The bubble is very thick, and extremely difficult to break out of, even repelling Akira Hiroshima's sound during training. With enough oxygen inside to survive for up to 3 days, the trapped person can be interrogated or kidnapped by use of this technique. Like all Explosive Bubble techniques, the bubble can be detonated at any time from anywhere, proving to be deadly. Atsuko has also been able to reduce the size of the bubble, eventually suffocating her enemy.
