This SR card was included in the Pokémon TCG XY BREAK "Blue Shock" expansion released in 2015. Azusa is a character from the Nintendo GameCube game "Pokémon Box: Ruby & Sapphire." While she doesn't have an active role in the main series games, she serves as a guide character for "Pokémon Bank," a service used to transfer Pokémon data between different Pokémon games. This makes her recognizable to many Pokémon players. In this particular expansion, she is the only Trainer SR card included.
