The storyline was really good but I think the mangaka was tired?
I don't think so because I really find it brilliant that the mangaka did a lot of foreshadowing on who's the real villain part. I'm really disappointed in myself that I didn't notice those small details that led to its plot twist (the maitre part!). He's really a known figure in urban legends that are related to vampires, so I was surprised at myself that I didn't notice it. Perhaps I've been too distracted with other stuff such as the steamy interactions of Vanitas and Jeanne 𓁹‿𓁹 ʰᵉʰ... I really like this anime, and I'm definitely looking forward to its season 3!!!
