Solar Release: Red Dwarf

Infusing a Truth-Seeking Ball with Solar Release, Fuyuki converts the orb into a miniature red dwarf, hence the name. She could then throw the orb and detonate it. A fiery orange explosion rips through the air. The next instant, she cools the orb down and it returns to orbit around her back.

Drawbacks
It takes quite the amount of chakra and it proved harmful to Fuyuki as she used it in a last ditch attempt at killing Astral Trinity. When fully recharged, Fuyuki's chakra does not take a dent when using this technique. Another inescapable drawback is that it takes at least thirty seconds to prepare, which could be easily exploited.
