Mai was the youngest of three sisters. She was living happily with them and with her parents also until one day, seven years old still, her parents decided to buy an abandoned hotel and went to live in there. After a month living in the hotel, Mai’s mother found a strange book and, thereafter, everything changed. Her mother began to behave oddly, as if nothing mattered to her, except the book; Shortly afterwards, her father disappeared leaving no trace and, being not out quite, her two older sisters fell ill and died strangely. This left the poor Mai, 9 at that time, all alone, with her mother increasingly isolated in herself.
