Nagasaki Arc (1-3)	When Hisoka gets angry, he and Tsuzuki start stealing each other's food. ^_^; Maria does not accompany Tsuzuki to where Hisoka is being held by Muraki.
Devil's Trill (4-6)	Before Hijiri is possessed, Tsuzuki goes to his house to cook. ^_^; Hisoka dies only once, when posing as Hijiri.
King of Swords (7-9)	Hisoka doesn't sense Muraki's presence on the boat prior to his (Muraki's) entrance. Muraki does not taunt Hisoka during the card game to win Tsuzuki. Wakabayashi has no vampire's bite marks on his neck in addition to his heart removal. The med student (Abiko?) is not targeted by Irene/Tsubaki-hime. The scene where Tsuzuki and Hisoka discover the organs in the ship is different.
Kyoto Arc (10-13)	I haven't read this part yet. ;_;
