After blowing dozens of bubbles, the user manipulates them to surround the enemy in all directions. Only the slightest amount of physical contact with an opponent is required to make these bubbles burst, resulting in a small but powerful explosion when they do. The user can then make the entirety detonate simultaneously with a snap of their fingers.
泡沫 is written with two kanji that both mean 'bubble'. The word can also be pronounced as 'utakata', also carrying the meaning of something ephemeral and transient like a soap bubble.
