During the day, Seira was a normal student. But after class, she changed into her white sister clothes and went to the church, which is on the school grounds. There she trained to be a sister.

Seira liked English and music, and her least favorite subject in school was physical education. Her favorite food was grape fruits.

While helping out Meimi and Saint Tail, Seira dressed up in many various outfits, as can be seen in the Seira photo album .
