Shrine&School

The girl from Musashino South High School was locked up on campus. Looking around, she found she was in a dark red room with screams from nowhere in her ears, long-lasting fear lingering in her heart, and objects scattered around. Not much to step into the shrine to pray, but she did not expect to enter the ancient barrier. She met the sealed thousand-year-old white fox. Mysterious dreams flashed in the girl's mind constantly. In order to find the way home, she kept collecting gou jade to break the barrier, but I did not expect it. Involved in a conspiracy designed hundreds of years ago? True or false? Right and wrong? What is the truth behind this?
