Seiren Funato

Seiren was a tan-skinned girl of slender yet curvaceous frame and average height. She had short, spiky orange hair with chin-length bangs framing the sides of her face and silver-coloured irides. Her most noticeable trait was three gill-like markings on both sides of her neck. She wore 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. When she was in disguise, Seiren wore a long orange wig and long grey robe with dark gloves. She also wore a white shawl around her neck and mouth.

As a child, her father Araumi returned from another raid and also brought with him a young boy named Tenma who he decided to adopt. Seiren later 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 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.
