Yume Kagura

The main character and Miko of the story. Although a somewhat simple-minded girl who pales in comparison to her perfect and talented twin sister, Yume embodies the power to save two worlds. As the new Miko, she is to gather up the four guardians of her own world in order to save them both. From the beginning of the story it is laid down that she believes in magic and casts protection spells on herself while she sleeps- which is why she was probably more accepting of her newfound abilities compared to other girls. Yume has a crush on Aoi, a boy at her school who is a student council member along with her sister, and who is also one of her protectors from this world. (Source: Wikipedia)
