Mirai is Takuto's first Seed-born child (the first he carried), and their 10th child. Inheriting Crysta's love energy and gassiness, because she was given so much energy, she manifested in the form of a 3-year old child, though her teeth had not grown in the day she manifested. Showing herself to be a quirky and fun-loving child, she already shows a great deal of intelligence and pride, though she's a bit clumsy too. In particular, she loves Saga, and shows interest in Chii's children as well. She takes after Takuto quite a bit, love traits and Crysta's eyes aside.
After Crysta helped her, Touka, Renai and Amias grow up into adults, she took Touka as her Mate and became pregnant with 3 children. She gave birth to three children before that thanks to Aika. As an adult, she seems very fiesty and straight-forward, but has an air of innocence to her as well. So far, she adores Touka and refuses to let him go for too long.
