katsuki Bakugo was 11 years old and was in a special hospital for hybrids because he was a wolf hybrid he had fluffy wolf ears and a fluffy tail amd fangs and was really aggressive to all the doctors and nurses because he hates having all the tests on him and he nurses grabbing him

One day bakugo was being his usal self amd fighing against the doctors and struggling when they brought in a new kid

he kid looked roughly the same age as bakugo he had long green hair and was really small the hospital robes drowned him

he was also a hybrid he had black horns little black fluffy wings and a black tail he looked like an adorable little demon he walked in with a nurse who was holding his hand and showing him around

when Katsuki saw him he stopped struggling against the doctors and froze his ears flattened against his head and his tail began to wag and his face flushed
