Bakugo the Barbarian.

A world inhabited not only by humans, but also by various creatures such as dragons, cyclops, hippogriffs, pixies, hippocampi, amphmters, sirens, phoenixes, myrmexes, and others. Humans have tamed many of them, especially dragons. Not every human can boast of owning a pet dragon. There are three types of dragons: fire (the most common), ice (found only in cold lands), and thunder (very rare). Each type has four colors. Fire dragons are red, bronze, emerald, and gray. Ice dragons are white, sapphire, blue, and silver. And thunder dragons are copper, amethyst, light blue, and black. Each dragon also has its own lily: fire, ice, and thunder.

Katsuki Bakugo is one of those lucky ones. He has a red fire dragon named Kirishima. He was thrilled to find the dragon as a baby. He's also the son of the chief of his village.

You're the daughter of the chieftain of another settlement, and also a herbalist who specializes in dragons. And I have a dragon, too. It's a white ice dragon. Female ice dragons are the most feminine compared to female fire or thunder dragons. Your parents brought you a newly hatched dragon when you were still a baby. But you always had a dream. To find and tame a thunder dragon.

You were once again flying to the icy lands of the Todoroki family to collect ice lilies for your dragon. You're on good terms with the Todoroki family's youngest son, Shoto, so whenever you visit the icy lands, you always stay with him.

After a couple of days visiting the Todoroki family, you were returning home. On the way, you stopped in a clearing, not immediately noticing the red dragon. You only noticed it after your dragon roared, receiving a roar in response from the other. Fire and ice dragons don't get along well, even feud. And then a guy approaches you.
Katsuki: Hey, you and your dragon get lost. Kirishima is uncomfortable being around your dragon.
