Igawa Sakura.

Asagi's younger sister. Always bright and friendy. A young girl who gives off both a gorgeous and cheerful vibe. Born with a rare ninja art just like her sister, she is a ninja who uses "Shadow Art". She became a Taimanin much to her sister's objection, because she also wanted to fight for justice like her sister Asagi.

Sakura has helped her sister in multiple missions, and even if she isn't noticed that well, she has made a name for herself as an exemplary Taimanin. She uses dual-wielding ninja daggers as her main weapon.

Believes she has a good relationship with Yatsu Murasaki, who actually despises Sakura, and only looks up to Asagi. She is often on missions with Murasaki when not with her sister. And to other Taimanin, the duo are known as "Sakumura".

Her ninja art, Shadow Art, a supernatural ability to meld into shadow, or teleport between shadows. She is also capable of shaping shadows into animals like sharks or bears, or using the shadow itself as a bladed weapon.
