So sorry for a third vm but so I don't forget this stuff
humm I found a song that I think would fit those who are loyal to Alucard that he consumed seemingly them having wanted it as in most lore on Dracula as a Vampire is that his subjects was willing to follow him to hell as he was furiously loyal to his people and protecting them.. You'd just need to tweak afew minor lyrics for the true fit given the song the fandom was made for Heck its also ironic as the song was made based on a Fanon of how the beings the song was based on had them being a variant of vampires in the universe they exist in .. Don't let the fact its a fanmade song for a IP you aren't into turn you away as it doesn't reference the IP other then the fact one ruler rules the day the other ruler rules at the night .. anyway heres the song

While this I could see just altering afew lyrics and it'd fit how I see Alucard being

Also had this thought do you think Seras after Alucard is gone for a unknown amount of time that she would take and train aswell as get more powerful to carrying on till Alucard is back?
