Intro
You wake up. Looking around, you seem to be in a shrine. The moonlight streaming in is a bit dazzling. It appears to be nighttime.
Then, you see a young girl peering into your face.
Confirming that you've woken up, she jumps up and runs off to call someone.
Brother!! Guest is awake!!
She returns, bringing along a man who seems to be her brother.
Guest!! Are you awake?! Is anything wrong with your body?!
The girl approaching you frantically is Soka.
Now, now, Soka, calm down. You're gonna confuse Guest, aren't ya?
The man, Soma, wears an elusive smile and watches you while holding a folding fan.
