Yin and Yang

Aside from the five elemental nature transformations, there are two nature transformations that are the source of all non-elemental techniques []

With that being said...

Kisame isn't listed as a user of Yin or Yang release in the databook[]. But according to the wiki, summoning has to be composed of Yin or Yang cause he can summon Sharks (Summoning Technique).

Same can be said for the 3rd Raikage. He can use Body Flicker and is known to use Body Flicker. According to the wiki, Body Flicker has to be Yin or Yang. But the 3rd Raikage isn't listed as a user of Yin or Yang[].

Another example is Hashirama. He used the Bringer-of-Darkness Technique in the Manga. Guess what he isn't listed in using? [] That's right. Yin Release. But wait, Yin Release is supposed to be all Genjutsu??? Yin Release.
