Tailed Beast Ball Rasengan

After entering the Nine-Tails Chakra Mode, the user generates a Rasengan with tailed beast chakra. The resulting technique is a handheld Tailed Beast Ball the size of a Rasengan.

Due to the high concentration involved in forming a Tailed Beast Ball, the technique originally failed when it was first developed, as it requires a 4:1 ratio of and  chakra respectively. Raian counters this weakness by creating two chakra arms. While his own hands create the Rasengan, the chakra arms add the black and white chakra.

The resulting Rasengan is incredibly heavy, requiring the aid of a chakra arm to carry it around. The resulting attack is so dense that it can smash a normal Rasengan with ease without losing its own form.
