Mirai Shishio is Tsukasa's younger sister. She spent years in a coma before the Petrification inadvertently healed her—one of those weird silver-lining situations the stone age created. Once she wakes up to this strange new world, she naturally gravitates toward the Kingdom of Science and quickly becomes close with Suika and Namari. The three of them end up being pretty inseparable, which is honestly nice to see given everything everyone's been through.
