Tayuya Lesidion

Tayuya was a member of Otogakure's former Sound 4, and a current kunoichi of Konohagakure.

During the Timeskip
After she was crushed by the logs that Temari blasted on her, she remained unconcious for a long time. She was brought back to Konoha when a medic squad was sent out to heal the members of the Sasuke Retrieval Squad. She was questioned, but when she revealed she actually knew little of Otogakure's inner workings as she took orders directly from Orochimaru, she was brought before Tsunade. Tayuya explained that she hated Orochimaru for abducting her as a child, and had only continued to follow him because she knew he'd kill her if she tried to leave. Tsunade gave her permission to join the Leaf Village as a Konoha shinobi, but assigned Yugao Uzuki to watch over her to ensure she did nothing that would harm the village.

After a few months, Yugao reports that Tayuya has done nothing worth suspiscion, and Tsunade allows her to live on unwatched. It is then Tayuya encounters Shikamaru Nara again. The two get into an argument that is broken up by Iruka Umino, who proceeds to berate them for arguing with each other over the past. Tayuya uncharacteristically apologizes to Shikamaru after Shikamaru shows discontent with the idea of forgiving her, in an attempt to one-up him. Iruka notices this, and he can't help but be amused at their rivalry.

Post-Timeskip
Tayuya eventually met Haku, who was recently revived and had joined the Leaf. The two became best friends. Haku balanced out Tayuya's fowl mouth with his manners, and Tayuya balanced out Haku's shyness and subservientness with her outspokeness. The two often went on missions together, and they were both paired with another former Sound ninja, Aniki Mitarashi, to enter their first Chuunin Exam together. They all passed with flying colors, figuratively ripping apart the competition due to their power being far higher than that of normal chunin.

Tayuya and Haku are sent on a mission to the Swamp Country to escort the Brotherhood of Crocos. They are ambushed by a horde of ninja from the Sisterhood of Gatros, and do battle. They discover that the Brotherhood had been kidnapping the Sisterhood's members for years, and the Gatros were only trying to rescue their "sisters". Haku and Tayuya settled the dispute by convincing the new leader of the Crocos to give the Gatros back to their tribe. Baryon, the vice chief, attempts to kill Haku in his sleep for getting "his woman" stolen, but Tayuya kills Baryon using Bolero of Fire. Haku greatly admires Tayuya from that point on for saving him. The two begin dating after that.

Abilities
Tayuya possesses a charka-imbued flute that acts as he primary means of attack. With her instrument, she can cast genjutsu, summon and command her Doki demons, and depending on the soundwave level, attack enemies. She can also cast some musical jutsu with it, including Bolero of Fire, a fire-type jutsu similar to Fire Style: Explosive Effort, Forest Melody, an earth-based jutsu that brings forth a group of flowers that all fire chakra bolts at the enemy before wilting, and Song of Storms, a wind-style jutsu that generates four wind blades that shoot at the enemy.
