Isari Funato

is a pirate from the Land of Water.

Background
After his father returned from another raid, Araumi also brought with him a young boy named Tenma who Asaumi decided to adopt. Isari happily welcomed him to the family. From a young age, they would train arduously together under their father's watch. He and Tenma would often tease their younger brother, Ikada, for not having any aptitude for battle or wielding the Funato power. Later, he watched Ikada's 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 save him from drowning, leaving Isari and his other siblings speechless.

After their father was captured by Kirigakure, Ikada made a decision to leave the clan and find his own path. Isari was strongly against this, but Seiren convinced him to let Ikada do as he pleased.

Personality
Isari dislikes quiet waters, preferring a rough, violent sea over a quiet, peaceful one. Composed by nature, he is very alert to the situation and thinks things out accordingly. In battle, he has shown a rather sadistic side, seeing his enemies as fishing targets. At the same time, he is very loyal to his family, losing his normally composed nature when anything bad should happen to them.

Appearance
Isari is a fairly tall individual. He has tan skin and blue eyes with straight, shoulder-length blond hair. His most noticeable trait is three gill-like markings on both sides of his neck. He wears white robes over a blue shirt and grey pants with black gloves.

Abilities
Isari is a capable fighter, considered the pride of the Funato Clan. Wielding a sentient marlin-bone spear, he was able to battle Kagura Karatachi, a prodigious swordsman, to a stalemate. He is proficient in Water Release, requiring no pre-existing water to create prisons or powerful waves to detain or attack his enemies.

Great Sea Battle of Kirigakure Arc
Isari sailed to Kirigakure, arriving by night with a fleet of ships, and discussed his partnership with a governor who backed him up. The next day, he watched as an airship crashed following the unveiling of the Shinonome 1 power station from a sea cliff.

Using the chaos as a diversion, Isari and his team broke into prison to free his father. There, they faced off against Kagura and Boruto Uzumaki, the latter of which his spear took quite the liking to. After succeeding in rescuing Araumi, they returned to the rest of their clan, who had used the chaos to secure control of several islands in the Land of Water.

Later, as Isari was enjoying a celebratory feast for his father's return, Tenma arrived, revealing that his ship and Chakra Cannon were destroyed by the joined efforts of Kiri and Konoha-nin. Isari deduced that it included the ninja he met in the prison. As Tenma vowed to hunt them down, Isari insisted that it was of no concern, as the Chakra Cannon already served its purpose to destroy the Land of Water's front-line base. Araumi agreed with his eldest son, convinced that they would win this war.

Later, Isari reported that the Mizukage had joined the front lines, the Funato Clan eagerly prepared for war. He informed his father that Seiren had went on ahead to take care of matters. Soon after, Isari joined Tenma and their main forces to face down the Mizukage. They were ordered to surrender, Isari smirked at the order. As the Kiri forces began repelling the Funato forces, Isari was pleased as their diversion plan was working perfectly.

As Tenma grew impatient with the stall tactic against Kirigakure's main forces while Seiren's unit attacked the defenceless village, Tenma voiced his desire to go directly after Chōjūrō. When he and Tenma received Funamushi's report that Seiren was injured and her unit was forced to stop their advance, Tenma's patience ran out. While Isari began devising a new plan, Tenma went behind his back and took a squad to attack and kill the Mizukage. Upon learning of Tenma's recklessness, Isari was very concerned. However, before he could act, he witnessed Tenma being struck down by the Mizukage and falling into the ocean. He gave the order to retreat as Kirigakure's fleet went on the offensive, and vowed revenge.
