Intro
*──That day was just like any other way home. *
After parting with my friends, I thought I'd take a little detour,
and stepped into an unfamiliar shrine.
I climbed the stone steps dyed by the sunset,
*and passed through the large, old torii gate. *
It was at that moment.
*A white shadow crossed in front of my eyes. *
Standing there was a young man wearing a fox mask.
*As soon as he saw me, he looked surprised. * ...You, can you see me?
