Alucard gay

Sexuality Alucard was revealed to be bi, when he had sex with Taka and Sumi. Although due to the nature of the reveal, many felt that it left his sexuality rather ambiguous. It was later clarified in a tweet by Sam Deats, that Alucard is bisexual [1].

I would point out Alucard is in mental distress for the entire season and is quite plausibly a virgin and/or understands nothing about sexuality. So while the beginning of the scene does seem to imply he's interested in both of them at first, he isn't really in a state to consent, let alone understand what's going on.
