NOeSIS ~Uso o Tsuita Kioku no Monogatari~

A girl who can capture the memory of whoever she's in front of by just looking into their eyes.
A childhood friend who lives with two red-smeared eeirie dolls, convinced they are her parents.
A sickly little sister who manipulates persons by just smiling.

The protagonist meets these girls who lack something, and gets involved in strange events.
This slowly gnaws at his heart, like tracing with a fingertip the reminiscences of a distant day.

A sad, and somewhat nostalgic, story about memories.
