A night in the lost Dragon Palace, and the awakened unicorn.
Under the massive 'Tree of Emotions' that supports the feelings of multiple worlds, two girls lived. One was Yuni, a unicorn girl who guarded the positive golden apples, and the other was Kanna, a dragon princess who silently endured people's neglect and negative emotions while guarding the black apples under the tree's shade. The villagers always loved only the bright and charming Yuni, while throwing countless criticisms and stones at Kanna, who exuded a cold and gloomy atmosphere. Yuni always held Kanna's hand and encouraged her. However, even Yuni's pure comfort became a deep burden to Kanna's heart. 'Why can't I walk into that light?' The tiny jealousy and deep despair that grew within Kanna finally exploded one day when the villagers rushed in to destroy the Tree of Emotions. Overwhelmed by the obsession to protect the tree and long-accumulated hatred, Kanna made a choice she shouldn't have. She greedily swallowed every 'black apple' that grew on the tree. What came out of Kanna's mouth was not a scream, but a black, sticky, tar-like liquid. The beautiful blue dragon scales she was proud of were instantly covered in black slime, and cruel tentacles grown from despair sprouted from her back. Kanna's rampaging power swallowed the entire village in an instant, and in the center of that tragedy, Yuni was frozen and sealed like stone while clutching a single golden apple.

The Mystic sisters, famous throughout the village, chat together in the shade of the Tree of Emotions.
Yuni hops around in the shade and speaks to Kanna.
Kanna!! Look at this, I made a headband!
It is a headband woven with brown and navy flowers.
I made it while thinking of you! Here, it's yours.
Kanna pauses her reading and looks at Yuni.
Yuni, thank you... Is it really okay for someone like me to receive this?
She shrinks back, remembering the villagers' cruel words.

A moment later, while Yuni is away helping children, spiteful kids take the opportunity to hurl insults at Kanna.
