Eterna has pale-fair skin and large black eyes accented by red makeup to match the mauve diamond on her forehead. She has dark brown hair up in a traditional Japanese style based on an Oiran and is adorned with a single light purple bow and six gold pins. She wears a purple kimono accented by mauve, ivory, and tiny goldenrod flowers. A grass-green obi is tied around her waist with white cloud patterns on it.
As long as she is holding her staff, Eterna is essentially an immortal being, however losing said staff will cause an almost instant transformation into her Grumples form. In the anime, she can turn anyone into babies.
Eterna can be freed from the Crank-a-kai with a Purple Coin, Excitement Coin, Five-Star Coin, or Special Coin. She can also be befriended in the Infinite Tunnel after 20,000 yards.
As of the Oni Evolution Update, she can also be freed from the Happy-Go-Lucky Crank-a-kai.
She first debuts in EP206, when she, in an older form that resembles a purple version of Grumples, comes to retrieve her staff which was taken by Whisper, who ended up turning into a baby when he retrieved it. Once she gets her staff back, she ended up turning into her younger self again. It's revealed that said staff is capable of making anyone young and rejuvenated, and that Eterna was using it to maintain her own youth.
Then, a group of old man Yo-kai known as "G6," which consists of Hungramps, Greesel, Papa Windbag, Illoo, Ol' Saint Trick, and Greengramps, suddenly appear before Eterna, desiring her staff so they could become young and handsome. The men then steal the staff from Eterna and each of them scramble to have it for themselves, before Eterna then steals it back.
Suddenly, a bright glow is emitted from the staff, and its power ends up spilling out all over Springdale, turning various Yo-kai into babies, including Eterna herself, with Nate miraculously being unaffected. It is then that Grumples herself arrives on the scene and steals away all the vitality of the baby-fied Yo-kai, turning them back into their original selves.
Grumples, having been revealed to be Eterna's older sister, then tells her that, after the events of Episode 69, she realized that she didn't need to be young to be beautiful, for you can still have a beautiful heart despite your outward appearance. With this lesson, Grumples tries to convince Eterna that she didn't need the staff to be beautiful, but this is revealed to be a lie crafted so Eterna could drop her staff and allow Grumples to take it for herself. After Grumples steals the staff and becomes Everfore, she ends up sealing away Eterna in a barrel while she admires her newfound youth in a mirror.
