Invisible Lover

In this Halloween-themed My Hero Academia doujinshi, Izuku Midoriya is a ghost and Katsuki Bakugo is a werewolf. Invisible to everyone else, Izuku is thrilled that Katsuki can actually see and interact with him. Taking advantage of his unseen status, Izuku touches Katsuki even when others, like the vampire Shoto Todoroki, are nearby. Their physical relationship escalates into explicit sexual acts, including Izuku giving Katsuki a handjob and Katsuki penetrating Izuku. Afterward, they discuss their bond, with Katsuki declaring that wolves only take one partner for life to solidify his commitment to Izuku.
