Sakurako Sakurakouji

Background
Sakurako is Sakura Sakurakouji's real mother. Sakurako is one of the Four Founders of Eden, alongside Heike and the Emperor. She carries the title of "The Amazon" among the founders of eden. She carries a long katana similar to Rei's. Her katana was revealed to eliminate both rare kind power and special power in recent chapters. She really loves her daughter. Her personality is somewhat of a mystery at this point, as are her intentions. The doll who restored the Emperor, Kurako, belonged to her.

There is a possibility that she also created Inoichi, another doll who is supposed to protect both Sakura and the Pandora's Box. All the mechanical dolls share the same emotions as Sakurako, allowing her to feel their emotions too. Since it was revealed that she was Sakura's mother, it was theorized that she and Shibuya were married. Later, it was proven true as in chapter 126 when Yukihina almost told Sakura that Shibuya was Sakurako's ex-husband.
