Yeah DOA story has never ever been superb so most stuff you'd have to link on your own or by other sources. The same could be said for other fighting games in general, and well, DOA is part of the abysmal story bunch.

yea, i feel like i followed it better when everyone had their individual stories in doa2-4. Now its like they try to find a way to include everyone and its a disaster lmao
