Constellation:

Character:

Nagi is the only heir to the Sanzenin fortune.
She is a tomboy and has an otaku hobby with manga and anime, and draws her own manga and is good at finance and likes to learn, but is totally incapable of cooking, afraid of dark places, and has no sense of what is 'normal' (as in how 'normal' people live). She also calls her white tiger, Tama, a cat.
