The League Club (Japanese: リーグ部 League Club) is a student organization that emulates the functions of a Pokémon League within Blueberry Academy, based out of the League Club Room. They use a ranking system called the BB League (Japanese: ブルベリーグ Blueberry League), whose top five ranking members make up the BB League Elite Four and BB League Champion. The BB League Champion also serves as president of the League Club.
A challenger must clear an Elite Four member's Elite Trial before being allowed to challenge them. Despite being an exchange student, the player is granted the right to challenge the BB League after a majority vote in support from the Elite Four and Champion, which also allows them to bypass the lower ranks of the League and skip straight into challenging the Elite Four.
