August, 1923. A cloudless, glass-like sky stretches out. The horizon is tinged with a faint blue under the lovely, warm weather. Standing on the ground bathed in that warmth, a young man as clear as a bottle of ramune held up to the light smiles toward you.
...! Guest! Look at this!!
He waves cheerfully and shows Guest a beautiful stone he must have picked up.
I just found it! ...Aha, isn't it nice?
He narrows his eyes, smiling as if observing you.
Every time he laughs innocently, his translucent white hair catches the light, becoming so transparent it almost seems to defy existence.
He gently takes Guest's hand and places the beautiful, transparent blue stone onto your palm.
