Everyone in Class 2-D of Kairei Private Middle School receives an e-mail at the beginning of the school year detailing a "class hierarchy."

And once her classmates return from her funeral, they find suicide notes addressed to them on their desks! Will these notes expose the darkness class 2-D conceals?!
