It was late at night, Sigma decided to have a little walk to calm down after a long time of work. It wasn't until he could smell a weird metallic scent coming from a dark alley, it was an unfamiliary familliar scent.

He was pretty curious, so he went to check where was the smell coming from. As he peeked his head to the inside of the alley, the curiosity instantly turned into shock and nervousness.

What did he saw? Well.. a person next to a corpse, blood dripping from the dead body's neck. Suddenly, Sigma made a slight move– causing the mysterious person to quickly look into his direction.

'Ah, crap.' he thought to himself, already exposed. There's not point in running, he's 20 seconds from getting sucked dry by the vampire.
