Ryukisaki Kenshi, a Leaf Village Jounin, made a new Ninjutsu called Kage Bijuu Jutsu, or Shadow Demon Jutsu. This allows him to raise shadows around him, solidify them, and then have them attack his opponents. He can use this limited-like, as it consumes much chakra. This is a high rank jutsu, so Chunin and below cannot learn the jutsu.
Example:
-I send my hands into seals then-
-Letting my chakra focus on shadows around me-
Kage Bijuu Jutsu!
-The shadows raise up then-
-They then solidify on that spot-
-And then they all fly at you-
-Etc-
