Kurohime, Vol. 4

Zero is tricked into helping a "Ghost Carriage" whose passengers are spirits seeking revenge on the bandits that killed them. Their leader lures Zero aboard but feisty Himekos not having any of it and a battle erupts. Zero quickly sees that the only way to save Himeko is to kill himself and continue fighting as a ghost. Will his selfless act inspire the love Himeko needs to regain her true form? And what does Kurohime do to incur the wrath of the gods above--again?!
