Simply by pressing Jump + Dodge (+ Direction) at the exact same time. The timing may take a while to soak in, but it's consistent and honestly - it's way more sexy than the poor kid's dodge. You can also flip over any Asura, which is finely dishonest and cool.
The metagame about it is that it allows you to jump slightly farther due to the positive speed boost from the dodge mechanic - which is naturally handy in many places and also in combat mode (making the jumps in battleground puzzles under attack etc.).
