Has no smut but the story definitely has defined plot.
Plot: Yuri average high school boy ends up in another medieval fantasy world. There he is told that he's the Demon King send to another world since the kingdom wasn't safe enough to be the place to grown up in. He has one duty kill all humans. Here he meets various attendant that despite portrayed as straight they have moments when they found Yuri cute, attractive and even see him like potential spouse.
This is most shounen ai and very family friendly.

Another reincarnation story.
MC wokes up next to his lover and remembers that in their past life (trauma) everytime they get together something bad always happens to him. Thus he decided to break up with his lover to save himself but seme/lover is not hearing any of it. I recommend this! Has fantasy. Angels demons etc

Not "transported to another world" but there's reincarnation involved.

Haven't read it yet but I remember the seme is from another world. Has fantasy.


If you're really eager for some isekai BL I recommend trying/searching on novel update. There's really some good isekai BL.
I HIGHLY recommend "Reader and protagonist definitely have to be in love"

Has fantasy. All races... Elf, undead, angels, people with animal ears, devils etc.
The protagonist is a reader that found himself in the novel he loves and he met the protag.
