The scavenger hunt is a nice change of pace from her usual training. While Ginia doesn't take it as seriously as others, she's gathered up a collection of prizes herself. The candy she keeps, the toys and accessories she's mostly passing off to younger shinki.

When Joss steals a prize ball out from under her as she's scaling a tree, she doesn't mind. He's young, possibly new. Good climbing skills. Even the second time doesn't get much more than a blink and willing surrender of the prize.

When Ginia sees him approach a plastic capsule nestled in a support beam after pushing some other shinki out of the way, her temper flares a little.

Line!

Ginia strikes her hand through the air. A barrier pops up a few feet in front of him, cutting off his path to the prize. Hopefully he noticed in time to not run into the borderline.
