I'm only up to episode 132, and I'm trying to avoid spoilers. That said, I wrote this the other day after a drive home thinking about Blood-Drinker, and I realised that it's totally Alucard as a sword and a one-track mind.
A brief extract from the past of blood-drinker:
Imagine a large, grungy city. You're carrying out your business as usual, when you feel an odd lurching sensation, almost pulling you upwards. You look up, and see Blood-Drinker hovering menacingly overhead. You feel a rumble through your feet, and you see red starting to leak through the stones of the street, and the pores in your skin. Your last breath is taken as you stare up at an ocean of blood winding it's way through the air, being absorbed by a glowing, blood-red sword.https://soundcloud.com/dominic-meehan/blood-drinker
