Raikage
Origin : Kumogakure
Recently introduced after the defeat of Hachibi, he is one of the five great Kage. His actual name (oddly enough) is "A". He is the older brother of Killer Bee, who is the jinchuuriki of the Eight-Tailed Giant Ox.
Killer Bee (Hachibi no Jinchuuriki)
Origin : Kumogakure
He is known as the jinchuuriki of Hachibi (the Eight-Tailed Giant Ox)and resides in Raigakure. He is very skilled in a Kenjutsu technique in which he places seven swords between the joints of his arms, right leg, stomach, the right side of his neck, and in his mouth. With the swords in place, he spins and confuses his opponent, taking advantage of openings that may occur (as with his fight against Sasuke). Even weirder than that, he loves speaking with rap-rhyme sentences. The true appearance of Hachibi is a giant longhorn bull with eight tails. He uses the element of Lightning in battle. Sasuke defeated him and took him to Akatsuki's hideout. Actually, though, Killer Bee is still alive because the body which was taken is fake.
Samui
Origin : Kumogakure
umm another big *cough* boobs character XD it seems Kishimoto-sensei loves fan service lol Samui is probably the leader of the team cuz she seems to be the most standout one amongst the others. however, Samui (which means Cold) is rather rare cuz she has light skin color unlike most Kumogakure villagers.
Omoi
Origin : Kumogakure
the one and only man in the team, Omoi (means Heavy) is rather foul-mouthed but frankly-speaking guy. he often argues with his team mate, Karui, about any lil things. skill is yet revealed but he uses the same sword as Karui.
Karui
Origin : Kumogakure
Karui (means Light) seems to be the partner of Omoi (check out their names which apposite one to another, Heavy and Light). yet Karui often brawls with Omoi about any lil things. skill is yet revealed but she uses the same sword as Omoi.
