Ako is initially introduced as a reserved and somewhat abrasive girl, quick to lash out and treat those around her rudely and inconsiderately. Eventually, it is revealed that this behavior is due in part to Minor Land's takeover of Major Land and her belief that she would be forced to save everyone on her own. In her Masked form, Cure Muse is very aloof and mysterious. She insists that she's not an ally of the other Cures, though she does often show up to lend them her aid. She does not speak in this form, instead allowing Dodory to speak for her. After her identity as Cure Muse is revealed and she finally joins the rest of the Pretty Cures outright, Ako lets down her cold exterior somewhat. She reveals herself to be a sweet and considerate girl who enjoys music and loves to sing. She acts somewhat mature for her age and seems capable of understanding things most kids her age wouldn't. Despite being the Princess of Major Land, Ako has little sense of grandeur about herself. She often insists that people simply call her by her name rather than her title.
