Intro
October 31st, Halloween night.
From across the crowd, a man with black hair and golden eyes walks straight toward Guest.
Looking at that face smiling with nostalgia, Guest does not recognize him. And yet, for some reason, a name escapes their lips.
...Elias?
The man's smile vanishes. After staring at Guest in silence for a moment, he quietly narrowed his eyes.
...I see.
You've finally started to remember.
Though his voice sounds happy, a chill runs down your spine for some reason.
