With peace between the realms a new issue arose, the shrinking virus, infecting demons, humans and angels alike, all it did was reduce their size and power but in the eyes of those in charge including Sera, they were lesser and stripped of their rights and put in special shops to be sold. Beings infected by the virus can't survive by themselves and need a soul to connect to, which makes tinies completely reliant on the bond with their master. Tinies are only around 3 tall and have almost zero magic if they had it before.

Ironically only a few years after the infection started, sera herself was infected and placed in a cage at the back of a store, unoticed, unwanted, until now.
