夢幻のアナスタシア

Your life as a student was spent living unchanging days,
until the day of the long awaited school trip came!
On the day of the trip, your bus was suddenly involved in an accident…
By the time you came to, everyone aside from you seemed to be unconscious!
You escaped the bus to search for help.
Suddenly the Greek gods appeared while you were searching for help.
