Bubble allows Kaoruko to make bubbles filled with an aroma that she has smelled at least once before.
Kaoruko's main usage of this Quirk is to create quick distractions that can temporarily blind foes as she restrains them.
She can make both sweet-smelling bubbles and foul-smelling ones. When Kaoruko is too nervous, she produces a very unpleasant-smelling bubble that self-destructs.
