Hmmm... I know that a dragoon is able to jump significantly higher than a normal person, but I'm unsure how long it takes for the ability to initiate.

[For all she knows, Yachiru might be able to do it right now.]

But as a ninja, you have access to an ability called 'Transience.' It will automatically allow you to dodge an attack and counter it with an attack of your own. It took me some time to adjust to this; I wasn't expecting it the first time it happened. But I'm certain you will be able to adjust with little difficulty.
