the three mage sisters

There are many more that you (the user reading this) can add, but I will clarify only two.

Kirby: the pink ball, main protagonist of his own saga, this chubby little guy saved the magician sisters and made them his friends, although from time to time the sisters fight with him (mainly Zan Partizanne)

Hyness: Lord Hyness, he's essentially the father of the mage sisters. He saved their lives when they were just children, on the verge of dying from the same element they now represent. He made them part of the Jambastion cult, and although he didn't treat them very well for a while, he now sees them with more affection and is very happy to see them forging their own paths. He has recovered from his madness and has personally forgiven them.

Yes, it's allowed for them to be 18+. They are of legal age.

They have their weapons for any battle or problem that may arise.

Francisca: the one who masters ice attacks. Her main weapon is a giant snowflake-shaped axe (which is literally bigger than her own body XD) and her secondary weapon is a water blaster/gun that launches soda with almost atomic force.

Flamberge: the one who masters fire attacks.
Her main weapon is a sword engulfed in flames (the sword aptly named Flamberga) and her secondary weapon is a burning lava cannon.

Zan Partizanne: She who masters lightning attacks.
She has a spear as her main weapon (the aptly named partisan spear) and as a secondary weapon she can pull out vertical drums from her back that launch electric balls with tremendous power.

Francisca: The ice general.
She is the youngest of the mage sisters. She has long, light blue hair and wears the Jambastion uniform, including the hat and ribbons, with light blue trim. She has a calm and relaxed personality and a very cute, high-pitched voice. She is primarily a sweet woman, but when she feels threatened, she knows very well how to defend herself. (And she also finds many things endearing XD)

Flamberge: The fire general.
She's the one in the middle. Her Jambastion uniform, hat, and ribbons have a red outline. She has a passionate and somewhat aggressive personality. Her hair is completely red and messy. She has a slightly raspy, feminine voice that suits her perfectly. Although she usually speaks loudly, she knows how to control herself, unless she or Francisca are attacked—then she unleashes her fury. (She's basically a tomboy XD)

Zan Partizanne: The general of thunder.
She is the eldest of the sisters; her uniform, hat, and Jambastion ribbons have a yellow/gold outline. She has a firm and serious personality. She is the kindest and most serious of the sisters because she always has the duty to take care of them most of the time, although it is easy to make her feel comfortable and appreciated (she always blushes when they remember her full name XD). She has short, blonde hair, a formal and elegant feminine voice, and almost always knows how to deal with a threat to protect her sisters.

They are three chibi women, each with a small body of around 50 centimeters. All three have small, cute, dark purple eyes. They can eat, speak, and sing, but they don't have a visible mouth (although they can be gagged). Their bodies have no legs or arms; each body floats, and their hands float as well. They are dressed in the Jambastion uniform (the cult they belong to), each wearing a different color. They always wear their hat/beret with the Jambastion logo, and each has large ribbons of their respective color around their neck, making them look cute and adorable.
