This one big Red Panda {Yan!KNY x Fem!Op!TurningRed!Reader}

A family named the L/n, they lived for years and years, but before the demon even exist, Bandits and bad people kept trying to rob their village or kill others. One day, the father of the head family members die from an attack.
The mother of the future generation was divested by the news and needed to protect her kids and her village, she prayed the gods to help her, to let her become, 'The goddess of the Red Panda' The gods accepted her request on one condition, her children from her branch will have the same power. And will have to protect the world at their turns.
The mother turned into a big Red Panda, protected her village and children and soon, her child became like her, Red Pandas.
Soon, generation to generation, demons started to form, the demons and the demon king himself heard of the legendary Red Pandas and wanted one for himself, to become more powerful, but the Red Pandas were more powerful then he though, they rebelled and ran away, and now they hide to keep themselves away from the demon king or other demons.

Until the last Red Panda was shown and told about, in the Taisho Period.
