As soon as she can move again, Chiaki immediately invokes the Ninja's Stealth to turn herself invisible. With her defense almost as low as it can get due to her combination of Jobs, she needs to make sure she's not an obvious target.

Trusting her invisibility to hold as long as she's not taking offensive actions, she pulls out her guitar and begins to play the Pac-Man Theme. As the repetitive song fills the air, the party will find its light-based attacks 50% more effective, with an accompanying 50% reduction in damage from dark-based attacks.
