Episode 78

Taboo, Three Illusions (禁忌､三幻式, Kinki, Sangenshiki) is the 78th episode of the D.Gray-man anime adaptation.

Summary
Kanda continues to fight Skinn. He activates his Taboo Three Illusions technique, but Skinn tells him that when Kanda cuts him with his sword, energy from Skinn is transferred into him. After Kanda finishes his attack, Skinn notes that he's cut him a lot, meaning the mass of energy now pent up in Kanda releases itself.

As their battle continues, the room begins to collapse. When it appears Kanda is about to be defeated, he slices through Skinn and defeats him. However, as Kanda nearly reaches the exit, we see that Skinn has survived and he says 'Noahs are immortal'.
