This troper has to give props to Ciel's path (specifically, the "How can you not hate me?" scene), and Hisui's True Ending (for the heartbreak and sheer guilt-trip that was Kohaku's death).
The Manga's rendition of that scene, and then the ending...this troper was on the verge of tears, and they were NOT manly. Arc's farewell just cut into the heart, and poor Shiki's reaction very much mirrored his own.
