Shizengan

A Rasengan variant which is completely composed of Natural Energy. This technique can only be used by those who have mastered Sage Mode, due to it's difficulty to concentrate and then form the surrounding natural energy into the palm of the user. Due to it not being composed of chakra, it can be a very useful and versatile technique.

This technique can be used without being in Sage Mode itself, though the user would need to stand still to gather the natural energy around themselves. Alternatively, the user may use a portion of their already-absorbed natural energy while they are in Sage Mode. Though creating too many at a time could have the possibility of kicking the user out of it.
