A gameplay trailer for Onechanbara Z2: Chaos released by D3 offers up some new info.
Not only does the trailer showcase the sisters in action, but as with Z introducing the vampire duo of Kagura & Sayaa, Z2 will be introducing another pair of sisters. Anzu & Sayaka are glimpsed momentarily during the trailer and curiously, they are Zombie sisters! Should make things a little more interesting. Catch the trailer below:
