Furui

was an elite shinobi from Kumogakure and member of the Eight-Tails Subduing Team.

Background
Thirty years before the start of the Fourth Shinobi World War, Furui was killed by the Eight-Tails during one of its scuffles, being impaled by one of its horns. His death strained the friendly relationship between his son Motoi and Killer B when the latter became the new jinchūriki of the Eight-Tails.

Personality
In the anime where his personality is expounded on, Furui was shown to be a very brave individual who loved his village greatly rallying the rest of his teammates to continue restraining the beast, since if they gave up, Kumogakure would be destroyed.

Appearance
Furui was a man with dark spiky hair. He wore round glasses, the standard Kumogakure flak jacket, a forehead protector, and shin guards. In all, Furui and his son bear great resemblance.

Abilities
Furui was skilled enough to have been selected by the Third Raikage as part of a special team that subdued the former jinchūriki whenever it lost control of the beast and went on a rampage. Furui was seen using a chain with a weight on the end as his weapon to hold down the beast. The anime expands on his abilities, revealing that he could use Lightning Release techniques with such skill that he was able to halt the beast's movements, thus allowing his teammates to move in and help subdue the beast.

Trivia

 * Furui can mean "ancient" or "trembling".
