She knows she isnt Oden and still consider Kaido as her father. But she wished to be him, cause Oden ist the Symbol of Freedom and Happiness in her cruel world. Imagine being her, threatened and tortured the whole life, always around these beasts and false creatures, which went rampaging and killing everything around. And then comes Oden, someone fighting for his freedom and fighting for someone else than just him. A man which was losing everything and still felt happiness, died with a smile, while her father is a suicidal mess, alcoholic and pure brutal. She didnt know happiness before, but saw it in Oden. Oden is her way into a life in happiness.
