Yin Shou Ninja

Yin Shou Ninja (voiced by Jun Seichi) was born in a ninja family with a long history. He who looks dull on the outside naturally inherited the ninjutsu passed down in the family blood. The Yin Guardian family has been responsible for protecting the Cyanotic Family for generations, and the Yin Guardian wants to protect the eldest daughter of the Cyanotic Family, Yuna Konwaka (voiced by Mai Nakahara). In fact, Yin Shushu has always been very sincere in love with Yuna, but the family tradition allows him to bury this feeling deeply in his heart. Yin Shushu and Yuna study in the same school. Here, they met many interesting friends - the daughter of the rich daughter Sawaka Airi (dubbed by Ryoko Shintani) who was born with a golden spoon in her mouth, and the swordsman Shinsou Tsubaki (dubbed by Sachiko Kojima) who wanted to kill Yuna but was gradually attracted by Yin Shushou.
