Sore Ike! Anpanman: Pantan to Yakusoku no Hoshi

Pantan, a red panda, carries an old promise made to an adventurer from his past: to find the treasure believed to rest inside a rainbow-colored star shining in the night sky. He sets out to fulfill that promise and crosses paths with Anpanman, who cannot ignore someone in need of help. The two combine their efforts and follow the path toward the star, where the value of the treasure itself begins to matter less than what keeping a promise after so many years means to Pantan.
