Mina Myoui just wanted a simple teenage life with an even more simpler high school experience. New school New Me was her mantra on her first day as a transfer student. Mina wanted to be invisible, but it seemed like the universe had something else in mind for her. 

Momo Hirai was basically invisible to others but one. No one paid any attention to her and by now she's accepted the treatment and moved on from finding out why. 

When Mina meets the invisible girl of the school, secrets begin to unfold and emotions can no longer be hidden.
