Sayu/Lore

==Personality==
Sayu is a seemingly eternally sleep-deprived ninja who uses her skills to hide from work and responsibilities. Her height is something she's deeply unsatisfied with, believing that sleep can replenish all her energy and help her grow taller.YouTube: Version 2.0 Special Program In order to live by this principle and have as much time to nap as possible, she honed her ninjutsu to perfection.
While she is particularly renowned for her apparent laziness, the members of the Shuumatsuban know that she is loyal to their cause as she would never go against their principles and wouldn't slack off on extremely important matters. Ayaka believes that Sayu's laziness came from her sensei's abrupt departure, as she looked up to them and when they left, became lost and confused.
Of course, from Sayu's point of view, this so-called "laziness" is just better time allocation which allows her to focus on things... like sleeping and growing taller. She does not like it when people pat her head, believing that doing so impedes her growth. She tolerates headpats from both the Traveler and Yae Miko, although the latter is out of fear of retaliation by the Guuji.
While a particularly skilled ninja, Sayu usually handles reconnaissance and other miscellaneous tasks. While she is trained in combat, the arts she learned were mostly intended for stealth and evasion. She appreciates the Traveler's company, willing to work harder for their sake. While dressed as a mujina, who she finds extremely adorable, Sayu becomes angered whenever people call her a tanuki, even going as far as to attack them.
==Appearance==
Sayu uses the short female model and is said to be pint-sized. She has short beige hair and reddish eyes.
==Official Introduction==
A dreaming companion that leaves no traces behind
A pint-sized, agile ninja associated with the Shiyuumatsu-Ban.
Height has never been one of Sayu's strengths... She stopped growing a long time ago, long enough that she feels like she is trapped in a dream where time has stopped.
Why aren't I growing taller? Am I not getting enough sleep?
And just like that, the pint-sized ninja who awoke to this thought drifted off to sleep again.
Sayu firmly believes that sleep can replenish all her energy and help her grow taller. In order to live by this principle and have as much time to nap as possible, she honed her ninjutsu to perfection.
Fleeing, hiding, transforming... Sayu is the master of all ninjutsu techniques. An unsuspecting leaf or a bucket? It might be just one of Sayu's many disguises!
As a result, if the Shiyuumatsu-Ban needs Sayu's help, they need to commit all efforts to finding her first.
Of course, from Sayu's point of view, this so-called "laziness" is just better time allocation which allows her to focus on things... like sleeping and growing taller.
