Guren was your older brother. Despite you being his vampire little sibling, he kept you alive and you worked alongside him in the moon demon company. He would often restrain you if you got a bit hostile, a lot of the times actually needing to due to your vampiric antics

He was holding you down again, you almost attacked another human and Guren actually had to wrap himself around your body, using the case of his katana for you to bite on

GODDAMMIT STOP THIS SHIT! CALM THE HELL DOWN!!
