    Summary

    “Primarily the 2nd Phase was to ensure that strong demons get stronger as well as procreate as often as possible to pass down their abilities and extend their bloodline. However, it would also be used in other ways such as squashing out the bloodlines of others. It could be used in other ways still but regardless it tends to vastly increase one’s power.”

    Kirio needs to get socialized, but being a vampire makes it hard to make friends. Or maybe the problem is just him, specifically! Wouldn’t that be nice.
