Sora Kaidou (海藤 空, かいどう そら lit. Kaidou Sora) is Shun's little sister.
Sora has shoulder length that has wavy ends and bangs secured with hairpins that form an x. She wears glasses like her mother. Sora was first seen wearing an overall dress with a collared shirt.
Sora is a rather serious person, particularly when it comes to academics. She appears to be short-tempered and scary like her mom, threatening Shun when he is being too loud and interrupting her studying.
- Her name, along with her little brother's, is based off of time-space travel (時空間移動 lit. jikūkan idō).
