Sōshūga

is the name of a pair of nunchaku that are used by Might Guy. Each handle of these weapons is intricately carved into the shape of a Chinese dragon-like creature, with scales engraved along their length and a head near the handle's base, while appearing to be linked together by a length of twisted cord. Guy wields these with great dexterity, utilising all of his limbs at times, making use of them particularly during situations where direct physical contact must be avoided.

The weapons are first seen in use during the later stages of the Fourth Shinobi World War but, during the course of the confrontation with Tobi, they were soon absorbed by the former and rendered unusable.

After the war, Guy wields the nunchaku once again. Due to Kamui's Dimension being unaccessible after Obito's death, it's most likely a new pair or a spare.

Trivia

 * In episode 40 of Naruto SD: Rock Lee no Seishun Full-Power Ninden, Guy can be seen holding a nunchaku with a similar looking design to Sōshūga, but with a black colouring.
