Mako Shiraishi (白石 茉子 Shiraishi Mako?) is a strong-willed girl who fights for her ideals. She loves children and worked at a kindergarten prior to becoming a Shinkenger. When she was a little girl, her childhood was pushed aside when her parents moved to Hawaii without a word and left her in the care of her grandmother, who schooled her in the ways of bushidō. Chiaki and Kotoha both regard her as an older sister figure; Chiaki even addresses her as such. Though she is a horrible cook (none of the boys can stomach her cooking), Mako tries her best in order to achieve her dream of becoming a good wife and mother. Eventually, Mako is reunited with her parents and learns that her mother had become paralyzed from the waist down as a result of her tenure as the previous Shinken Pink. After the reunion and reconciliation with her mother, Mako gains a newfound conviction to defeat the Gedoushu. Because of her gentle nature, she can read other people well, especially Takeru, and readily gives her opinion regarding the situation in question. After the final battle, Mako goes to Hawaii to live with her parents.
As Shinken Pink (シンケンピンク Shinken Pinku?), she is the Samurai of Sky (天の侍 Ten no Samurai?), can borrow the Inromaru to become Super Shinken Pink (スーパーシンケンピンク Sūpā Shinken Pinku?), and can perform the Pink Double Attack (ピンクダブルアタック Pinku Daburu Atakku?) with Gosei Pink in Tensou Sentai Goseiger vs. Shinkenger: Epic on Ginmaku.
