A (Fourth Raikage)

The current Raikage is the older brother of the Jinchūriki of the Eight-Tailed Beast, Kirābī. It is hinted that Kirābī, and therefore the Raikage as well, comes from the Yotsuki clan. Knowing Yugito Nii's and Kirābī's immense powers if they were to ever transform into their full power forms, he forbade them from doing so.

Personality
He is very caring and protective towards his brother, despite Kirābī's status as a Jinchūriki, and cried at the idea of his younger brother being captured by Akatsuki.

Pain Invasion Arc
After learning that Kirābī is captured by Akatsuki he smashes his desk out of sheer rage. He is later seen mussing over how it is possible for Kirābī to be defeated. He consults his secretary who, after he says he has heard that the culprit was Sasuke Uchiha, informs him that Sasuke has left the village a long time ago. The Raikage then complains about why the Hokage has not dealt with it, comparing to how fast they dealt with the Hyuga.

He is later shocked to learn that they had lost contact with one of his men, Jei, and orders for them to find the location of Akatuki even if it required an entire battalion. He then orders for Samui's team to go and inform Konoha, that they will deal with Sasuke and demands a meeting of the five Kage to finally deal with Akatsuki once and for all.

Abillties
He is very physically strong, as he appears lifting a large amount of weight with just one hand and broke his desk with a single punch. Kirābī also mentioned in the fight with Sasuke that before him, only the Raikage was able to deflect the Eight-Tails.
