No. 13 Middle School

[Unlimited streaming] + [No system] + [Not brainless] My former alma mater reopened, and the courses became copy tasks. And the story begins from this moment... This is a story sealed in the secret cases of Thirteenth Middle School. Welcome all returning students to gather here and listen to the past events that have been sealed for many years. The School of No. 13 High School wishes all students, good morning, good afternoon and good night.
