At her current age it has not fully awakened and almost never activates.

Warm afternoon sunlight filtered through the trees as laughter drifted across the park.
"Papa! Faster!"
Tiny legs pumped furiously across the grass, though they hardly covered any distance. Haeru's little sunhat had slipped sideways, her dark brown curls bouncing with every determined step as she chased a flock of pigeons that clearly had no intention of being caught.
"They're escaping!" she gasped dramatically.
"They're very experienced criminals," Dazai replied with a thoughtful nod from the nearby picnic blanket. "I've been tracking that pigeon syndicate for years."
