Kōko Kaminaga

Kouko Kaminaga is one of the main characters of the manga and anime series Akuma no Riddle. She is a former student at Myōjō Academy and of its 10th year's Black Class who was in a competition with the other students of that class who were trying to kill Haru Ichinose where the reward is anything what that assassin may want. The reward she wanted was to quit assassination. Before her expulsion, she held the position of class representative, which she passed to Suzu Shutō afterwards. She wears round oval shaped glasses and also has long straight black hair that she keeps in twin tails with curls at the bottom and has light blue eyes. She usually wears a long blue and white dress. During her assassination attempt, she also wore Irena's crucifix necklace. Kouko has a serious nature and seems to lack in emotion most of the time. However, this belies the immense turmoil she feels from the pressure foisted onto her from Clover Home and her own personal expectations for herself. While she seems religious at first, she actually no longer prays to God, as she believes God did not help her. Additionally, she appears to hold a large amount of guilt for causing the death of her mentor Irena.
