I did a search with google to look for anime series that has “vampire” in it’s plot and that’s when I found Lament of the Lamb 「羊の歌」. It’s 4 episodes, each 20 minutes, and I’ve decided to give it a go since I’m just looking for short series  that has vampire in it. At the end of everything, I felt so cheated, confused and if you’re to ask me for my opinions of ending, frankly, I can’t remember what the ending was and the significance of it’s ending.
