Ōwashi

Ōwashi (イヌワシ, Ōwashi) is a lizard from Kuroishi Island. Born under the name Ōkami (オオカミ, Ōkami), he eventually became the Great Sage of the Black Sand Beach area of Kuroishi Island, and discarded his birth name.

Background
Like the other lizards born on Kuroishi Island, when Ōkami hatched, he had to fend for himself and never knew his father or mother. Shortly after hatching, he and his brother Subako teamed up in order to survive and eventually grew to care for him as a sibling instead of treating him like a rival. He and Inuwashi would eventually settle near the Black Sand Beach and would begin their senjutsu training at the age of 10. However, unlike his brother, Subako decided to join the Blue Mist Senjutsu school instead of the Black Sand School, causing a minor rift with his brother. After 14 years of training, Ōkami became the strongest practitioner of Black Sand senjutsu, adopting the name Ōwashi, simultaneously discarding his birth name. Some time afterwards, he and Inuwashi put aside their differences and began to train together for the first time in in over a decade.

Years later, at the age of 25 Ōwashi would meet Team Kazuki and formed a summoning contract with Illia Tatsumaki.

His outfit consisted of a Kirigakure flak jacket with a blue and orange pin-striped shirt, dark shinobi pants and a brown Kirigakure headband. The headband would later change to the one of the allied shinobi forces during the Fourth Shinobi World War.

Senjutsu
