Japanese shinobi. Loves sushi, fundoshi and shibari.
Kage-chan was found as a young boy by a ninja clan member and asked if he could also become a member because all the members of his family were murdered by some gang's members, so he wanted to become a great ninja and dismember them one day.
So he took the hardest training from the greatest members of the clan but eventually was never sent on any missions because was too cute and talented. They send him to rhythmic gymnastic competitions instead, so he could please his thirst for beating other guys.
