I'm still bothered by how similar the outcast Ayashi and Alucard are.
Miyabi, Hokuto, Kiria and Mido all have similarities to Alucard. The protruding weapons, spikes, blades, the texture of their transformed skin and their physical appearances are all very Alucard-like.
This could be a product of Alucard having ingested countless youkai and become a hybrid being himself, or it could be that they're successful Alucard infused beings.
Either way what bothers me the most is Kiria himself, because like Tsukune he has different colored eyes with one of them resembling a vampire eye with a slitted pupil and red iris while the other looks more like a frog eye.
