Chuterubisu Academy is an international school in Japan. It includes an elementary division, a junior division, and a senior division. The senior division is entirely separate from the rest of the academy, located on a mountain far from the other two divisions. It is also split by gender and follows a unique tradition: the senior-junior system.
At the boys' school, this means each upperclassman is assigned to look after one underclassman.
Stranger still, none of the senior division's third-year students can be found...
On their third day at this academy, Teng Xihen and Shangguan Luanwu find a corpse in the chapel. What kind of mystery is Chuterubisu hiding?
