Seeren Klein is a freshman student at Arzew Academy and the twin sister of Seere Klein.

Seere loves hats and always wears one. She, also, always wears 6 cm high heels. She is an egoistic person. She is too much preoccupied with herself and hats, to care for something else. She is indifferent and unfriendly, even hostile, towards people she doesn't know. She shows no interest in staff considered important in Crepuscule. She doesn't even pay much attention to her sister's or best friend's (Ersha) needs and worries.

She has been a student of Arzew since elementary. During this time, she and her sister became close friends with Ersha.
