Cthune

クー音

Kuuko's distant cousin and a Cthugha, dispatched to Mahiro's residence to oversee her, harbors an intense infatuation with her. Like her cousin, she serves as an inspector for the Plantary Defense Organization.
When Kuuko was young, she manipulated her into declaring a desire to marry Kuune in the future, an admission Kuune recorded and broadcast to the entire school.
