Yakuza 5 to feature Dance Battles alongside the regular punching ones
Haruka's "battles" take the form of a rhythm game in which you compete against rival dancers. As you perform, you'll build up a gauge, much like the "Heat Gauge" in the series' non-dance fights. And, like in those fights, you'll be able to perform special moves when it's full – in this case, Dance Heat moves.
There's even a parallel RPG mechanic, in the form of "expression power," which is awarded at the end of every battle by spectators.
