Pocket Monsters SPECIAL: Emerald

The chapter begins with focus on a Trainer named Emerald, who is sent by Professor Oak and Crystal to catch Jirachi within seven days. On arrival at the Battle Frontier, he accidentally interferes in the opening ceremonies and gains the second challenge of clearing the seven Facilities by defeating the Frontier Brains within that time. During this time, Emerald befriends Todd Snap and discovers that the masked Guile Hideout is seeking Jirachi for evil purposes.
