The Shooting Star is a Keychain for Sora's Keyblade in Kingdom Hearts III.
Sora receives the Shooting Star after leaving Little Chef's Le Grand Bistrot for the first time.
In San Fransokyo, Sora uses the Shooting Star against the Heartless while collecting data for Hiro Hamada. His actions with the Shooting Star inspire Big Hero 6 to upgrade their weaponry.
