Sora appears to be short-tempered and scary like their Mom, she was serious into studying. Shun can't stand up to her and she threatens him that if he's being too loud she will tell into to their Mom.

Trivia

 * Toki 時 means time, and Sora　空 means sky (or empty), but when 空 is combined with the character 間 it becomes kuukan 空間 meaning “space” (like physical space, not outer　space)- so when you put their names together (with the kaidou -> kan idou) you get Jikuukan Idou (時空間移動) = travel through time-space (ie another way to say time travel)
