Koga, Itami
Summary
Koga is a sixteen-year-old second-year student in Class 13 of the Thirteen Party. Although her blood type is AB, her mental state is classified as abnormal, a significant shift from her previous normalcy. Her abnormality manifests as an accelerated recovery rate, allowing her body to heal damage at an extremely fast pace. Previously, Koga lived a mundane life in the normal world, which she found overly ordinary. Seeking change, she approached Youka Naze, whom she deeply loves as a friend. She remains by Naze’s side constantly, even when Naze makes poor decisions or conducts experiments on her. During her final year of middle school, Koga transferred schools due to her father’s circumstances. There, she met Naze, a meeting that drastically altered her worldview. Despite protests from her classmates, Koga approached the isolated Naze, having known nothing about her, and asked her to do something crazy together.
