That was the last time I saw her smile. The cute tiger teeth can be vaguely seen at the corners of the raised mouth. They are as bright as before, leaving no trace of haze, and they are worth protecting at any cost. However, just a moment later, she disappeared into the void. This memory is like a note hanging under a glass wind chime, swaying, spinning, and flashing in the air, and seems to be disappearing soon. And when the wind blows, it can actually bring about those people and things that were thought to have disappeared, echoing from the abyss of the brain sulci. Mutsu Mamoru, you really look like a person. I think... Probably my sister!
