By being confident, sarcastic, stubborn and a smart mouth, she actually turned into a person hard to reason with, as she knows what she wants and won't back down, no matter what. She is only quickly persuaded and easy to reason with if a Pokémon or her friends/family are involved. Loving Pokémon and her family and friends more than anything, moves her to do anything to save them or gain their trust, even blocking her own skill of reading their thoughts unless they allow her, and will go to great lengths to achieve that, showing how caring, loving and selfless she is. By believing and trusting deeply on Pokémon and giving them a sense of trust, safety and being loved, made her earn the name of "Believer" as she believes in Pokémon and their skills, and is able to bring out the best on them for those reasons.

As Hikari was nearby, she fought to protect the Pokémon that lived in the lake, however in the middle of the fight fell off on top of Feebas resulting in her capture. That event didn't leave Hikari very pleased since she wasn't the Pokémon Hikari wanted, but since the Feebas was on her team, Hikari nicknamed her taking into her hands to train Mika, despite the criticism to her appearance.
