The Ho Yay in Trinity Blood varies, depending on how you look at it. Abel seems to have a thing for Tres, especially in the manga.
Also, Radu and Ion.
Radu and Dietrich too. Radu couldn't shut up about how beautiful Dietrich was while he was being tortured.
Esther Blanchett and Shahrazad al-Rahman's very special friendship in the novel and specially the manga adaptation, cue to a lot of Fanservice.
Also, Jane and Mary in the novels, considering that Jane has dark curls as hair and Mary is a redhead and Esther's older half sister, it seems to be a common pattern.
