Unlike many of the other Wonder Egg girls, Ayaka seems quite headstrong and attempts to attack her Wonder Killer without help or direction from Neiru, much to her protector's annoyance.

When Neiru scolds her, she apologizes for her forwardness but admits that she can't stand the scent or look of her Wonder Killer. She also expresses gratitude to Neiru after her Wonder Killer is defeated.
