The objective: To investigate on an evolutionary method, which manifests itself with the bonds of humans and Pokémon, an evolutionary method for humans. For that Professor Ceibo together with 3.... well 4 mercenaries to help you. Brigham, a bard with a face of few friends accompanied by his Chimchar, Lily's older brother. Lily, a girl who supports her cowardly Chikorita from a distance. Murchadh, a berserker with a good heart but who doesn't talk much about his past, accompanied by a friendly Mudkip. Finally Valentina, a thunder mage accompanied by a rather lazy Shinx.
