While I’m inclined to believe this won’t be of much interest to people here, I was quite surprised to notice (rather late, I know) there’s also some male (Ikemen) Yandere Drama CD goodness - Yandere Heaven, with the second volume released last month.
Oh and somewhat topic-related, something for Yandere sweet tooths I picked up in Akiba - Yandere Cookie sooo delicious
