Tōka Senju

was a member of the Senju clan prior to the founding of Konohagakure.

Background
She was a close and trusted associate of Hashirama during the time before Konoha was founded.

Appearance
Tōka had light eyes, an oval face, a dark shade of lipstick and wore a very stoic expression on her face. Her dark hair was tied in an elaborate and intricate top-knot, with a bang covering the left side of her face. She wore a dark suit with the standard armour of that time over it. In the anime, her appearance was changed somewhat as she is depicted with dark eyes, a pointed chin, no lipstick, and a less elaborate top-knot.

Abilities
Though the extent of her skills goes unknown, she was renowned throughout the world for her prowess with genjutsu.
