Yokumensu

Yokumensu the Second (第二のよくめんす,Daini no Yokumensu) feared as the Emerald Avenger (エメラルドアベンジャー,Emerarudo no Abenjā) is mysterious proclaimed hero from unknown origins.

Background
Yokumensu's roots can be traced back all the way to the Second and Third Ninja Wars. Him and his father, Yokumensu the First came from a Clan of Blacksmiths. The weapons they crafted where distributed throughout the Ninja World to aid them in battle. After the death of his father, he became the the Clan Leader and decided to lead the village to a more peaceful approach. Instead of crafting weapons to village who pays the most, he decided that weapons should be instead, given to weaker villages to help them defend themselves from getting in the crossfire.

Unfortunately, Yokumensu crossed paths with a disguised Shugohime, appearing as a beautiful queen. In an attempt to deceive him for weapons, Shugohime asked that he and his most skilled clansmen come back and make weapons for her small kingdom. Yokumensu's Clan was stricken by poverty and a shortage of supplies, so in attempt to carry the weight, he himself went with Shugohime. However once her got there, she asked that he's make a single weapon, more power than any he made before. And because he had so little to work with and was kept in deplorable conditions, he left her and returned to his village.

Upon his return, he found his village in flames and without a doubt accused this as Shugohime's doing. In a failed attempt to kill her, he lost his left arm and swore vengeance for his people. After replacing his arm with an artificial one, and collecting the finest and most refined of materials, Yokumensu spent days working non-stop until he finally created his "ultimate weapon", Junsuihauru.

Personality
Yoskumensu is an honorable Ninja, holding a deep hatred against Shugohime and those who slaughtered his clan. Although he casually wears a serious, "no-nonsense" facade, he harbors a comical personality when he is talking or fighting against his opponents, being described as "quirky and humorous" by witnesses and observers. After starting his journey, He devotes his entire life to destroying the evils that corrupt the world, and wants to erase those he believes should not exist. Besides Shugohime, this also includes Jinchūriki which he believed are "impure".
