Seiren Funato

is a pirate from the Funato clan.

Background
As a child, Seiren watched nervously as her younger brother, Ikada, was forcibly put through a rite of passage ceremony to determine his inherited power. As Ikada was hurled into the ocean as raging storm took place, his Funato abilities manifested, causing a massive wave that saved him from drowning, leaving Seiren and her brothers speechless.

Later, after their father, Araumi, was captured by Kirigakure, Ikada decided to leave home to pursue his passion for boats, Seiren was the only one who supported him, and the two have kept in touch. However, she did so in hopes that Ikada would discover how corrupt the Land of Water was, and return on his own.

Personality
Seiren is very committed to her clan and father. So loyal, she tolerates no acts of betrayal, striking down an entire island for allying with Kirigakure after her father's capture, even if the people were old and/or defenceless. At the same time, she has a soft side, caring for her younger brother Ikada and trusting him to find his own path. However, this ultimately falls back to her loyalty to the clan as a whole, wanting Ikada to find his pride as a Funato. Taking pride as a person of the sea, she feels people who grew up in cities are spoiled. In battle, she enjoys mocking her opponents' situation.

Appearance
Seiren is a tan-skinned girl of slender yet curvaceous frame and average height. She has short, spiky orange hair with chin-length bangs framing the sides of her face and silver-coloured irides. Her most noticeable trait is three gill-like markings on both sides of her neck. She wears a white tanktop above her navel with small brown vest, grey bandages about her arms, a simple necklace with three beads, and brown pants that was torn on her left leg with a long black legging.

Abilities
As a leading member of the Funato Clan, Seiren is a powerful shinobi. She is noted to have never lost a target. She also has a talent for disguising as a bystander.

Bukijutsu
She is capable in kenjutsu, using a blade to strike down her foes. Her specialty in battle is archery, using her ray shaped bow to fire off chakra arrows to snipe her targets. Beyond the damage of the arrows, they also paralyse the opponent by disrupting their chakra flow. By plucking on the strings of her bow, she can also change the arrows' path after they are fired to circumvent blocking attempts. Also with strings, she can detect people in an area through echolocation.

Ninjutsu
Seiren can produce a black fog, capable of obscuring herself and her ship.

Great Sea Battle of Kirigakure Arc
Following Isari's successful rescue of their father, Seiren joined the family for a feast to celebrate. As they discussed the continued growth in their clan's number of followers, Tenma arrived. He revealed that his ship fortress was destroyed, along with its main cannon, by a team effort of Kiri and Konoha-nin. As Seiren was shocked to hear of this team-up, Isari and Araumi, however, remained unconcerned, noting that it was no longer necessary for their plans.

Later, as word reached that the Mizukage had joined the front lines, the Funato clan prepared for war. Meanwhile, Seiren went ahead to an island filled with clan traitors. She was also eager to meet up with Ikada. After killing the traitors, she sought out Ikada in secret. As the siblings caught up, Seiren insisted that it was time for him to return to the clan. Ikada refused, believing his place with was his ship-building teacher, Kajiki.

Seiren refused to accept it, demanding that Ikada do what was needed for the clan, especially with his inherited power. As she left and promised to return for him that night, she walked by Boruto Uzumaki. Noticing his Konoha forehead protector, she realised he was among the people who destroyed Tenma's ship. Upon returning to her men, she told them they would kill all on the island but one, making sure word spread about the Funato might.

As her team attacked the island, Seiren quickly found Boruto, who had created shadow clones to protect himself, weary of the black fog. Refusing to elaborate why she targeted him, she continued to fire at him, paralysing his arm. Kagura arrived in time to block one of her shots, and explained to Boruto how she tracked him through echolocation. Boruto made use of the thunderstorm to throw off her tracking, and coordinated with Kagura, allowing him to sneak up on her and strike her down. Wounded and unconscious, she was rescued by Funamushi, who brought her back to their ship. Despite their differences, Ikada was furious that Seiren was hurt.
