Wolverine: Soultaker #1

Wolverine is in Japan visiting Yukio when she shows him a necklace called the Mark of Mana which has been causing her to have terrible visions every since she touched it. Wolverine takes it to an old friend for identification who tells him that it is evil but is killed by ninjas before he can tell Wolverine why. Logan touches the necklace himself and begins to see visions of his own.
