Deadman Wonderland/Ho Yay


 * In Deadman Wonderland, the relationship between Nagi and Genkaku has lots of Ho Yay (also overlapping with Foe Yay). It starts off a bit more subtle, with Genkaku seeming a bit too intense and obsessed with getting Nagi to join the Undertakers (along with an interrogation scene between the two, where Genkaku is shown licking the blood from Nagi's arm and calling Nagi "cute"). Later, however, the Ho Yay levels go through the roof when Genkaku is shown getting incredibly turned on by Nagi killing some poor sap, saying that Nagi is a "red flower that has bloomed." After that, he later pretty much gives Nagi a love confession telling him that, and that he loved him. And that's not even mentioning how annoyed and angry Genkaku gets whenever he sees the possibility of a girl getting close to Nagi (in regards to Shiro, he is shown being extremely agitated, wondering what relationship she has with Nagi, and saying that Nagi never learns. In regards to Karako, he ). And later, . Ah well, he's just biased that way.
 * And apparently, to the disappointment of shippers, the author ended up killing off both of them, cutting off the massive amounts of Ho Yay they were generating. Thankfully, Mockingbird has now been introduced, who has a similar sort of Blood Lust and kinky way of flirting and fighting. His interactions with Ganta and Senji certainly are... interesting.
 * Also, Makina and her assistant, though it seems one-sided from the latter towards the former.
