15 feet jump

When the avian monstrosity lifted its wings a second time, D kicked off the
ground with incredible force. Flying almost straight up, he rose over fifteen
feet. His extended left hand latched onto the ankle of the massive bird the
other was carrying. Having taken a deadly blow to a vital spot, the lower
bird was already dead. And the girl it had captured had fainted. Using his
left hand as a fulcrum, D swung his body like a pendulum. In midair his
coat opened and, adjusting for wind resistance, D sailed skillfully onto the
back of the larger bird.
