Miu Shinonome (voiced by Misaki Watada) is previously detailed character Kaito Shinonme’s younger sister. She is an eccentric sixth grade student who often speaks in riddles. She dislikes her brother’s interferences and always rebels against him.
Syakomon (voiced by Asami Tanako) is a bivalve monster covered by a hard shell, as well as Miu’s partner Digimon. As she protects Miu from dangerous monsters, they gradually become friends. Though Miu tends to daydream, Syakomon keeps her grounded. Her and Miu make a good pair.
In Digimon Survive, a group of students attending an extracurricular research studies camp end up lost in another world where dangerous monsters exist. Both Miu and Kaito are locals to the area where the camp is being held.
