Ugh another demon daddy~ Eugene is such a precious lil bean. I love how genuine he is with his devotion to Johann. Also Sigurd and Eiji I wanna read their story.
After a long ago war between the humans, demons, and elf races, the demon king Johann brokered peace and took over ruling everyone. Now, a young half-elf man named Eugene has come to serve him as a priest, and Johann is immediately interested in tasting his magic (via sex), only to get blasted back when he tries! Turns out that Eugene is the grandson of Johann's rival from the war and he put a seal on Eugene to protect him from Johann. But now that Eugene is willing to go all the way with Johann, they need to find a way to get rid of this dang seal! Also featuring a side character who got isekaied into this world, so that's fun. Trigger warning: attempted rape.
