Riddle Story of Devil

How to Distinguish a ''Congratulation'' from a ''Curse'' (1x11)

:

With all the other assassins defeated, Nio announces there will be an orientation held at midnight revealing the secret behind Class Black, implying that Haru already knows something. That night, Tokaku and Haru arrive at the orientation, where they are greeted by Yuri, who reveals Class Black was designed as a test to see if Haru could survive against twelve assassins and become a successor for her clan, who control most of the world. Yuri implies that Haru, consciously or not, allegedly has the power to manipulate and control others into protecting her, which Haru refuses to acknowledge. As Haru runs off in denial, Yuri asks Tokaku to think of a wish she wants granted for winning Class Black. That night, as Tokaku feels she had been manipulated the entire time, with no way for Haru to prove otherwise, Kaiba tells her that all of the riddles he had sent her have no "right" answers, tasking Tokaku with finding her own answers. Meanwhile, after Haru asks Yuri to let her leave the clan and live a normal life, Nio takes her to their clan's cemetery, which Myōjō Academy was built upon, giving her some time to reflect on things. After spending time with her family's grave, Haru is approached by Tokaku, who delivers her own advance warning and draws her sword against her.
