Kinderella, also known as Miss Universe, is a woman who married Wapol after he became the head of his own corporation. Two years after that, she became the queen of Black Drum Kingdom when Wapol became its king.
Kinderella is a slim woman with purple hair whose mouth is often seen open. She wore long purple dresses, and was seen by others as beautiful. After becoming the queen, she added a dark cape with bat wings on the shoulders, a hood with a crow design, long light-colored gloves, and an eye-mask.
Kinderella enjoys listening to her husband insulting other people and laughs profusely when he does so, indicating that she is as rude as he is. She sometimes adds "-universe" as a suffix at the end of her sentences.
Like many other people, Kinderella has a unique laugh: "Koshi koshi koshi" (コシコシコシ,"Koshi koshi koshi"?)
Two years later, she was still married to Wapol and they were now the king and queen of the new Evil Black Drum Kingdom, due to being rewarded by the World Nobles for their company's enormous success.
Kinderella's name is likely based off of the fairy tale character Cinderella. This is ironic, given that it was her husband who rose from a life of poverty and tedious work, while she already possessed the title of "Miss Universe".
Her name may also be based off of Kinder Surprise, which are chocolate eggs with toys inside them, which fits with Wapol's job as a toy maker.
