Tamako Doi

Tamako Doi is a highly spirited and active girl who excels in physical activities but finds studying quite difficult. Known for her restless and transparent nature, she wears her heart on her sleeve and can easily burst into joy or anger. On the battlefield, she wields a unique bladed shield that she operates much like a yo-yo to fend off hostile forces. She shares a remarkably close, sister-like bond with her junior, Anzu Iyojima, and constantly looks out for her well-being. Ultimately, her profound devotion is proven when she bravely sacrifices her own life to shield Anzu from a devastating Vertex assault.
