Haru Shinagawa

 (品川ハル, Shinagawa Haru) is a chūnin-level shinobi of Kusagakure and the jinchūriki of Kokuō, the Five-Tails.

Background
It was an average day when Haru was born in Kusagakure. His mother was with him while picking flowers at the meadows. Haru's mother knew about the news that the Five-Tails was caught by their village and the Village Head was finding an infant to seal the tailed beast. Haru's father wanted him to become a weapon when war comes, but Haru's mother was trying to stop her husband. Later on, Haru then became a jinchūriki, much to his mother's dismay.

Haru was hated by the villagers due to his current status as a jinchūriki. His father was very proud that he will soon become a weapon for war and finally stand in the front-lines. His mother was very angry at her husband and took Haru away from his father. Haru and his mother then lived in a house at the corner of the village.

During the age of seven, Haru already helps her mother in taking care of Kusagakure's rice fields and plants thus developing his love for nature. After a few days, his mother introduced to Haru his father and how he became a selfish husband. Haru's father felt very sorry and started to reunite with his family again. When he reached the age of nine, he graduated Kusagakure's Academy and became a chūnin at the age of twelve.

Personality
Haru is a kind and generous individual. He is also quite loyal and is willing to lay his life on the line for his friends. He also helped Hana Namiho, a complete stranger, when he found her feeling ill and alone in the forest. Sometimes, Haru becomes bubbly that can sometimes border into being silly or even ditzy.

Haru shows love for plants, as he treats them as his friends, to the point that her mother thought that Haru was already out of his mind. He also greatly cares for forest and fields; thus gaining more will during battle if the opponent accidentally destroys a tree or creates a crater in a grassfield.

Haru also has a strange relationship between him and his tailed beast. His tailed beast, despite being quiet and calm, likes to tease and underestimate Haru because it thinks that Haru is very childish. Despite the tailed beast's treatment on his jinchūriki, Haru calls it Gobi-kun and always asks if it wants something.

Appearance
Haru is a slender, young man that bears green eyes and somewhat long, neat blonde hair. His skin is average, and also his height. His appearance changes throughout the story.

In Part I, Haru often wears a long-sleeved green jacket over white polo shirt, along with a white waist bag. He dons a pair of striped beige pants and black boots. He also wears two fishnet bands in both of his arms and bandages on his legs. In certain times, he wears a green vest instead of the jacket and a pair of striped green shorts as a replacement for his pants.

In Part II, Haru now wears a black robe with white trimmings. A white ribbon is tied around his neck and his waist. His boots are replaced by a more formal pair of boots and another pair of ribbons around his boots. Sometimes, he wears a royal formal suit during important events and happenings.

Abilities
Haru specializes in using converting his chakra by sealing into objects, that allows him to control any of the five natures or combine them to use a different nature. He also specializes in fūinjutsu and taijutsu.

Nature Transformation
Haru uses Wind Release in a very different way. He manipulates the air around him to make it explode or lower the oxygen level in the area. He can also create his attacks invisible, making a surprise attack on the target.

Chakra Conversion
Haru uses a set of techniques that revolves around converting sealed chakra. He merely seals his chakra on cards to be able to convert it and use for battle.

Chakra Prevention
Haru is allowed to use a hiden technique to stop the flow of chakra in the target's body. However, it may only be activated through physical contact but Haru seems to be able to activate this also through a mental command.

Taijutsu
Haru is flexible and can defeat a large crowd without getting hit. He can also create sneaky surprise attacks in order for no one to know what he did. He can also do a triple jump or more by focusing his chakra in the air or the force he uses to rise.

Fūinjutsu
Haru merely seals his cards in small scrolls, and sometimes seals other objects inside the cards. He is also excellent in using the scrolls as he can throw it in the air and unseal the cards without touching them, giving him a big advantage over the whole battlefield.

Jinchūriki Transformations
Haru seems to have a high-degree in controlling the Five-Tails, as he can control its chakra from taking over him. He can also manifest all of its five tails. Haru can also control its transformation and how much chakra he or Kokuō uses.
