Shizuku

was a shinobi who hailed from the Land of Demons.

Plot overview
Shizuku is a member of Yomi's team on a quest to release Mōryō. During the first encounter with Naruto and his team, he demonstrated impressive fire-chakra skills that nearly killed Naruto. During the second battle, Shizuku performs the initial attack to separate Shion from her protectors by attacking them with an enormous Water Dragon. Neji is surprised to see that he has such tremendous mastery of water-chakra because he detected no such chakra in him during the previous fight.

After Naruto's team separates, Shizuku faces off against Naruto. Immediately, Naruto is forced on the defensive from his incredible water-based attacks. Whether he took to the sky or hid in the forest, he could not shake Shizuku. Eventually Naruto manages to outmaneuver him through his shadow clones and hit him with a Rasengan, only to see him laugh it off by turning into water. He then revealed that his goal was simply to separate him from Neji before escaping. Later, after Neji deduces the secret behind the enemy's unusual power, Shizuku and his team get tricked into using up their enhanced chakra. While weakened, Sakura strikes and finishes him off by punching him into a tree and killing Setsuna with the falling tree.

Abilities
Shizuku is shown to be a graceful fighter with maneuvers of a rhythmic gymnast. His primary battle tactics while under the influence of Yomi's dark chakra revolve around water-chakra. He can easily create large scale jutsu that can overwhelm the entire area or attack from huge distances. He can also move at great speed with little effort by gliding on a stream of water. If faced with a life-threatening attack, he can turn himself into water.

Trivia

 * Although Shizuku seems quite feminine, he is, infact, a boy, but their have been fights about his gender.
