Shinobu, Mariko

信夫マリ子

Mariko is Nanako's classmate and sits near her. She is immediately drawn to Nanako. A very beautiful girl, she shares the desire of others to join the Sorority and takes great pride in her looks. She wants Nanako to be her closest and best friend, and feels intense jealousy toward Nanako's friendship with Tomoko. Consequently, she attempts to sabotage that bond by spreading lies to Tomoko.
She vigorously defends Nanako on several occasions, though her behavior can sometimes be excessive. Her occasionally odd attitude toward others stems primarily from serious family issues. Her parents' relationship is in crisis, and due to her father, Mariko completely distrusts men.
For a period, Mariko risks losing Nanako's friendship forever. She harbors deep feelings for Kaoru, and eventually becomes friends with Tomoko as well (only in the anime version).
