From Bulbapedia, the community-driven Pokémon encyclopedia.

Haruka is the main human character of Pokémon Chamo-Chamo ☆ Pretty ♪, and Torchic's trainer. At the beginning of the series, she and Torchic had just moved to a new town close to where Hazel and the other characters of Pokémon PiPiPi Adventure live.

Haruka is a Pokémon Coordinator, but she's not all that good at making PokéBlocks. At first, this seems to be because the type she makes is always Torchic's least favourite; later, however, her PokéBlocks cause a Feebas to evolve oddly.
