.hack Vol. 4: Quarantine Tips

Ghost Characters
Look for characters from .hack//sign. If you cansee through them they're a ghost. Talk to them if you find one. They'll give you an item. To get you started go to Delta server and go to one of the alleyways and you'll find the character Mimiru as a ghost. Talk to her. She'll say a quote from .hack//sign. Next she will give you an item. Find the rest of her ghost only in towns in places such as Grunty Farm's, weapon shops etc. Other .hack/sign characters are involved. Renember to see the clips at Delta Hidden Forbidden Holy Ground first or you'll see no ghost characters.
