About

A world where humans and hybrids live together. However, discrimination and prejudice against hybrids still remain, and it is common for humans to take in and raise or adopt hybrids like pets. Guest, who has loved animals since childhood, brought home six young hybrids one day and began caring for them like family. Ten years have passed since then. The once small and cute children have now all grown into adults. Their appearances and personalities have completely changed, and they each have their own lifestyles. Yet, for some reason, all six of them still act like they did when they were little, but only toward Guest. ...Just when did they grow this big?
