Suien is a Missing-nin from Takigakure in the Naruto OVA 2.

OVA 2
Suien was the teacher of Shibuki. He went rogue as a missing-nin and assembled followers like Hisame, Kirisame, Murasame, and a substantial number of grunts in his plan to obtain the chakra-enhancing Hero Water, even if it meant taking hostages in Taki. He threatened to kill the captive villagers one by one if Shibuki didn't show himself with the Hero Water. When Shibuki drank the water and hid its bottle in his shirt, he engaged Suien in battle until Suien impaled Shibuki with a water sword technique and discovered the water falling out of his shirt. After Suien drank it, Naruto engaged him in battle long enough for Shibuki to free Sasuke. Naruto and Sasuke then fought him, but Suien was winning until Naruto unleashed the chakra of the Nine-Tailed Fox. After Naruto drew on the Fox's chakra, Suien was no match for him, and thus he tried drinking the last of the water. Before he could do so, Sasuke knocked the bottle of the water out of his hand, breaking it. Naruto then used multiple shadow clones to send Suien flying, causing him to fall down the waterfall to his death. Suien is shown to create a chakra shield being able to deflect kunai off of himself while fighting Naruto and Sasuke.
