Sanae Nagatsuki

Driven by an intense, obsessive infatuation, this classmate and childhood friend of Eiko Aizawa spends her time documenting Ika Musume through endless photography. Though she frequently experiences bouts of jealousy and retreats into romantic delusions, she possesses a surprising level of discipline when Eiko requires her assistance with serious tasks. Despite being met with physical rejection and ink sprays from her unrequited love, she finds a strange, masochistic joy in the pursuit, often accompanied by her pet dog, Alex.
