Amber is the second daughter of the Yukon family and younger sister of ZOE.
She is a cheerful mood maker. She can get along with anyone. However, she is free-spirited, doesn't listen to others, and doesn't take in the atmosphere around her. Her all-too-natural personality makes a good impression on those around her, much to their annoyance.

She and her Pokémon are not master and servant, but more like equals than other trainers. They control her free-spirited nature and sometimes play pranks with her.

Of course, she's also very strong in battle; the Yukon family is even stronger than the Pokémon that main the battles.

Kohaku is a Grookey that Amber adores. It's been her partner since she was participating in the Gym Challenge. However, it doesn't evolve at all. Still, it's over Lv.80.
