TEKKEN 8

This is most easily done during Chapter 1 in Story: The Dark Awakens. Play this chapter until both Jin and Kazuya grow wings and shoot lasers at each other during a mini-cutscene. After this they are both buffed with more health and a new moveset that deals more damage. Now playing as Jin make sure you are in Special Style (press LB to toggle it, buttons will appear in bottom left when Special Style is active) > activate Heat with RB > spam Y button repeatedly for an air combo. This will deal 70+ damage. Because both characters have more health and deal more damage in this fight you can easily get it here. Note that this isn’t the first round of Chapter 1, you must keep playing through the Chapter 1 fights until Kazuya (your opponent) grows wings on his back.
