Tatewaki, Tsurugi

ツルギ・タテワキ

Tsurugi, the red Sword Eyes of Light, was taken from his homeland following riots. He was sent there along with his protector, a droid named Bringer, and one of the 12 Sword Braves. He lived with an elderly couple, unaware of his birth origins or his older brother, Yaiba. He possessed a talent for skateboarding and dreamed of becoming a pro.
When attacked by a white droid, Stinger, Bringer awakened and gave him a deck to battle with. Bringer instructed him on how to play, as Tsurugi was not aware of the rules.
After the battle, Bringer revealed the truth about Tsurugi's past and showed him a hologram of his mother. Tsurugi's village was attacked by Cornell, a member of the green army of the Sword Eyes of Darkness. He was forced to battle again to save his grandmother, but managed to win. Tsurugi's grandparents encouraged him to search for his real mother.
He soon met Vargas, who appeared in the form of a white light. Vargas offered the red Sword Brave of Darkness to Tsurugi. He accepted it because he needed the power and because he thought using the darkness might help him understand Yaiba. Then, he became the red Sword Eyes of Darkness. Tsurugi battled Vargas with a new deck he obtained soon after and defeated him.
It was said that Tsurugi was the first ever case of a Sword Eyes of both Light and Darkness.
