Kihō

was a shinobi from Otogakure and a member of Team Guren.

Personality
He seemed rather blunt and went along with Rinji's strategies without complaints. Kihō also feared death to which he referred to as "going boom".

Abilities
Although he did not receive much screen time in battle, his weapon of choice was a wrist/arm-mounted rocket launcher that fired projectiles, which made him a long-distance fighter. The smoke he emitted was capable of obscuring even a ninken's sense of smell and he was able to form the smoke into a dragon which can envelop and suffocate the enemy and due to being made of smoke was immune to physical attacks. As shown in his defeat by Yamato, he appeared to be weak to Water Release. He was later given a Cursed Seal, which granted him an increase in chakra and raw power, but if he does not take a pill after a certain amount of time, the seal would kill him by tearing him inside out.

Three-Tails Arc
He was one of Orochimaru's prisoners that was selected to join forces with Guren. When Guren left with Kabuto Yakushi and Yūkimaru, he was instructed to stay behind to deal with Team Kurenai and Team Yamato. He was easily defeated by Rock Lee, Tenten, and Kiba Inuzuka. Later, Kabuto forcibly activated the groups cursed seals. Kihō was then ordered to attack the Konoha ninja again. He and his team succeeded to defeat the first defence team consisting of Kiba, Lee, and Tenten. After doing so and retrieving Yūkimaru, Kihō and his team initially planned to run away from Orochimaru's grasp, only to find out that their cursed seals would kill them if not properly taken care of. Forced to stay, Kihō and his team were sent to stop the Konoha ninja from sealing the Three-Tails. He went against Yamato and ended up getting killed after Yamato destroyed his Smoke Dragons with his water technique and crushed him with his wood jutsu. After his death, Nurari merges with him and Kigiri into a monster and they fought against Kakashi and the others. As Kakashi was about to kill them, they where killed by the rampaging Three-Tails.
