Ryuu no Yuigon
sex-driven maou of the eastern continent and his half-dragon servant. more plot, with little smut so yeah. it's good for fantasy and adventure-loving readers. it may not be marked finished by mangago but the story looks like it and there's author's notes at the bottom too.
Kyou Kara Maoh
Super amusing & wacky collection of really, really handsome men and their not-so-innocent bromance. OK guys. If you ship yuuri with wolfram stay at manga+anime (but anime is more harem-y). If you ship him w/ Conrad, there are moments at the light novel. https://www.baka-tsuki.org/project/index.php?title=Maru-MA

I really won't get tired rereading this manga. The concept is so out of this world (literally!) and that made it entertaining. I am loving the salaryman life mixed into supernatural idea. Right up my alley. In for a rollercoaster ride. This manga gets more angsty by the minute as the story goes on. . ./ vol. 2 ch. 4: usu (heavenly god) x ran (original enma) backstory. ch. 5: main couple's beautiful conclusion.
Datte Maou-sama Wa Kare Ga Kirai
tsundere-ish hate and love mesh-up. sexy and hot manga about two natural enemies, demon king and hero who battle each other out in bed.

Ch. 1-3: #tsundere uke x depressive seme / god uke x human seme. I'd say... Love the story & artwork but the humanism superiority complex are a bit unpleasant. It's a hit or miss in mangas. A courtier(seme), desperate for the emperor's favour took advantage of a god's naivete and took him to the city to play dirty politics. Literally. Dislike ep. 1 but I'm glad that there's something more to seme. Thankfully, uke as a powerful being was able to see seme's innate goodness. God fell inlove with seme and decided to help him. And they live happily ever after. I'd say fell inlove too fast like a shoujo heroine but it's not bad. I'm happy for them. .//. Ch. 4: #handsome, long-haired seme x cutesy, adorable uke. Oohh this is pretty good lol. A for-laughs manga. In order to save the world, the Hero must have sex with someone? He won't be getting one asking around like that tho. Hero had sex, it will go "KABOOM" and the world gets purified. Convenient isn't it? Short and shallow but that made it entertaining. .//. Ch. 5: #game-like. uke!maou x heteromorphic slime (means can become human) seme. Wow, the entertainment has just levelled up. Uke Demon King (they're usually seme) just wanted peace but the heroes are not giving him slack by attacking his minions for EXP points. So he saved that poor slime and the slime thanked him not just by turning into tentacles monster but suddenly he became a macho man and I JUST HAD TO THROW MY PHONE AND ROLL ON THE BED LAUGHING. I... I... got su-sannned!!!! ps. is it me or the hero looks like the hero from chapter 4?
Maou Uke BL
{Demon king-themed Anthology} I'm saying, It's such a treat to see a maou: That all-powerful being as a bottom (*coughtakingituptheasscough) and I just love it whenever I found one. And an anthology at it! Pretty little shiny belongs to my collection now.
Yuujin ga Yuusha
Ohh set in dark ages. The classic hero x maou rivalry.
