ポケットモンスターSPECIAL: ルビー・サファイア

This chapter features the journeys of Ruby and Sapphire who are trying to conquer all the Pokémon Contests and Gyms in Hoenn respectively within the span of 80 days. However, this gets interrupted by two new evil organizations, the land-loving Team Magma and the sea-loving Team Aqua. Sapphire and Ruby have to worry about something else, too: their feelings for each other. (Source: Bulbapedia)
