A variation of the Tailed Beast Ball Keika invented. Keika could use a normal Tailed Beast Ball as well but she likes this variation of hers. Using the properties of her Soap Bubble Ninjutsu, Keika combines it with a normal Tailed Beast Ball, creating a variation that could float around. It could detonate either automatically or manually. Keika controls the floating mass of chakra with her mind and she could also turn it invisible, meaning she could sneak it into enemy territory and detonate it without any warning signs.
