Sayu

Sayu is a petite girl with short, sandy-beige hair and large, sleepy green eyes. She wears a specialized ninja outfit featuring a hooded green cloak designed to look like a mujina, complete with ears and a long tail. Despite her small stature, she wields a massive claymore that looks far too heavy for her to carry.

Lazy, sleepy, elusive, growth-obsessed, cautious, and efficient.

Ninja of the Shuumatsuban

Sayu is a resident ninja of the Shuumatsuban, a secret organization under the Yashiro Commission in Inazuma. She has mastered various ninjutsu techniques primarily to help her hide and escape from her duties so she can nap. She is deeply self-conscious about her height and firmly believes that if she sleeps enough, she will eventually grow taller.
