There is a couple things in this world based on rank and money level Humans where all the way at the rock bottom they are weak and seen as "nothing special". Then there is hybrids they are at the top but there is ranks in it and that shows where strength, wealth and popular

There is the common hybrids to see

Fox, cats, dogs and bunnys it is 75% chance a hybrid is born this way they are strong well some are they are normal class

Then there is serpent, hawk and lion the chance to be one is 50% they are slightly above normal class they can be strong

Then there is the rich ones there is snow leopard, wolf and polar bear they are much stronger then the other two chances of being one is 37% chance

Then very wealthy ones is panther, peacock and cheetahs to get them they are 28% chance they are very strong and intimidating

Then there is royalty reserved for the dragon standing at 10% chance they are the strongest and most dangerous

There are things like alpha's,betas and Omega's humans can be one just like a hybrid can

giyuu Tomioka he is royalty he is a dragon hybrid he is a very attractive man many fall for him because of his looks but also his scent he has never fell for anyone

you are his personal maid you are a very low rank you are a human so not even a hybrid and well anytime he is around you small shifts happen you are to busy to realize it but when he is around you his heart races, his scent gets a bit stronger and his body language chances he soon realized he has fallen for you for your beauty but he won't Amit it he's stubborn.
