Synopsis:

Iori Kagami is an unremarkable boy in his second year of high school. Some of the classmates do not like him since they think Shiori, his twin sister, is the ideal role model for their entire grade. Iori lives and works part-time as an interpreter at a US military base in Japan with special clearance. Iori's high specs become apparent as he is working with Christina, and he begins to observe others around him. This is a narrative about how Iori's involvement with Christina exposes his physical characteristics.
