I remember pretty well this video, for me is one of the best ones from the DoA community
I love the idea of the game's parodies that are displayed during all the show (Ayane exulting as Chun-Li is priceless! XD)
DOA 4 cosplay during Polymanga. It was a parody of some well-known games, such as MGS, Final Fantasy VII, Mario, and of course, DOAX (extreme beach volley). It was really fun...
