Serina

Unlike the lively and energetic Amy and others from the dog clan, Serina is naturally colorblind, seeing only in black and white in her world. She has been ostracized by other children, with only kind-hearted Amy playing with her. Serina spends all day at home reading, making her exceptionally shy, not good at interacting with anyone other than her parents and Amy. Immersed in books, she loves reading adventure stories, especially those that describe protagonists reincarnating in another world, making her yearn for the day she can embark on such a journey.

The intelligent Serina received an opportunity to be the exchange scholar to other Academic Cities. Without a second thought, she chose to study abroad for a short term in the thirteenth Academic City where Amy is.
