Biography: Yume was born under a highly respected family of nobles, her father a great friend and attendant of the sixth Kazekage. For years Yume trained under the top medical nin after graduating to chūnin at the age of 12, showing promising use of her bloodline abilities combined with the use of senbon.

During the chūnin exams, Yume came close to being disqualified upon throwing a mistakenly perfect aimed senbon at a fellow genin and severing an artery in his leg, almost killing him. Her aim was classified as "too perfect" as she could pierce a target bullseye with her eyes closed. It was upon this that realisation struck amongst the Hasu clan - Yume was no ordinary shinobi. Battle came naturally and she was practically invulnerable in melee and ranged combat. The co-ordinators of the exams decided that Yume would return to her squad, instead she would practice her already legendary acupuncture skills with the Kazekage's most trusted team of medical nin. Thus, her aim was honed so finely that she could purposefully hit a vein or incapacitate an enemy from hundreds of metres away. The training also brought her practical skills, such as close combat abilities and experienced chakra control.

Her skills were put to the test when she was asked to accompany the Kazekage on a mission to eliminate a small team of rogue ANBU that fled Sunagakure and hid in a base in he desert, intending on assassinating the sixth Kazekage. The man himself chose to deal with the situation, taking along with him Yume and a small team of trustworthy ANBU. During a fall-out with the rogues, the Kazekage was critically injured and left the allied ANBU to fight the enemies. Outnumbered, their chances appeared slim. Yume tried healing the man with the help of her senbon and first aid kits yet to no avail. He lay in the sand, his breathing shaky with a hand to his heart. The young kunoichi was decided the man only had a few minutes left before he was no longer, so she took matters into her own hands. Asking the remaining ANBU to step back, she took a gamble and used a skill that if used correctly would end the fight if not come close to. If failed, Yume would be left with little to no chakra left alongside a dead Kazekage and litter of bodies. Using Acupuncture: Storm, Yume summoned from the skies an incredible amount of senbon, raining down on the rogues and piercing every amount of flesh and skin on their body.

Yume returned to the Kazekage and held his hand in his last seconds, until the last breath escaped from his lips. She and the last two ANBU arrived in the village with the Kazekage's crippled body in their arms. It was undisputed that Yume was to claim the position of Kage of Suna, and so it was.

Acupuncture: Pain
Yume uses her senbon on hand to cripple her opponents in vital places, inflicting incredible pain and agony. Pain can be used as a ranged attack or melee. This does not require hand signs.

Acupuncture: Paralyse
Similar to Acupuncture: Pain in that Yume pierces vital locations on the enemy's body, Paralyse disables certain parts of the body depending on where the senbon is aimed at. Can be used as a ranged attack or melee.This does not require hand signs either.

Acupuncture: Storm
Yume summons a rain of senbon from the sky. Pretty self explanatory if you ask me.

Acupuncture: Slash
Using senbon and the help of her Swift Release, Yume launches a series of quick attacks at a target, slashing a large amount of times without pause to cause painful flesh wounds. This attack can only be used for melee purposes.

Acupuncture: Removal
Rather than using senbon for offence, Yume uses needles to prevent pain or blood flow in a specifically targeted area.

Yume also has the ability to summon senbon made from her own chakra, although it limits the amount of skills she can use and becomes extremely tiresome when large amounts are summoned.Yume also has the ability to summon senbon made from her own chakra, although it limits the amount of skills she can use and becomes extremely tiresome when large amounts are summoned. In addition to this, Yume can also perform slightly above average-level healing ninjutsu although it is not her strongest point. During melee combat, Yume will use her senbon in a similar way to that of Slash except slower and more precise. Her senbon is specifically manufactured stronger and more durable, meaning using more than one at a time results in a reliable shield from attacks.
