Tsukasa Tsutsukakushi

Tsukasa was the mother of Tsukiko and Tsukushi, who died when they were young due to complications from an infection caused by a flood. She was a very nice person, although she sometimes sounded mean. Following her husband's death, she had her daughters move to Italy and live with her husband's parents due to her poor health. This caused a rift to form between her and Tsukushi, who believed that her mother had abandoned her and Tsukiko. While living alone, Tsukasa handmade clothes for both Tsukiko and Tsukushi, and also took care of Yōto, who would keep her company. Tsukasa was reunited with her daughters prior to her death.
