Title.

Come up with a fake isekai title that sounds so unreal that it works. If, unbeknownst to the poster, the title is actually real, whoever points it out gets a cookie.

I'll start: destroying the demon king's moonbase in a medival world for my employment

This is basically Light Novel Title Generator™

I Have The Ability to Sense Boobs so I Know Where the Demon Queen is Hiding

Hmmm


I got reincarnated in a world of flat chests so I decided to steal the heroine's harem.

My Time as a Demon Queen's Personal Undercover Sex-shop Deliveryman

Spoiler

@fagguette101 so guess if this..

..is real or not?

Hmm.. not real, cause moonbase and medieval doesn't work well together (unless maybe it's like Goblin Slayer where he said Goblin came from the moon)...

Hey wait, is this actually Goblin Slayer???

The busty loli-goddess reincarnated me as the hero, but I am a shut-in, so I became the demon lord instead.

I seems to be the only male in this world but since I'm a yuri fan I'm gonna go kms.

I got summoned to another world but another summoner from earth summon me back before I obtain any cheat abilities, so now I am an average human in average world eventhough my great-grandpa was a self-proclaimed sage, trying my best living in an (imaginary) slow mofu mofu life using my vast medieval period knowledge from searching on bing which is now mostly outdated and pretty much useless in this modern era, when I realize my age I am already an actual fat wizzard (30y/o virgins) which still have chuunibyou disease, my fiancee ( a common black company slave ) broke our engagement before dying and reincarnated as a saint in another world and my family try to throw me into monastery via the HELLO WORK agency, but knowing whats going happen to me I'll try to change my fate as a mob in this world until finally I understand that I'm the villain on my own life.

I reincarnated as the Demon Lord, so now I’m pretending to be the hero.

@Nolonar I'm pretty sure that actually exists.

I know a series that is "I'm both the demon lord and hero" exists.

In another world, I’m a useless vampire!

They Summoned Me Into a Dystopia of a Fantasy

Ngl I'd read the synopsis if I saw a title like this.

I'm getting summoned into Grand Theft Auto with cheat and Mod.

Well, the real one isn't GTA but TES, but I'll stop right there with no comment added.

@MoonlightFairy
Skyrim belongs to the nords!

"I opened a door to a different world and got myself a girlfriend, but she's also now a real magical girl"

"I've been reincarnated into an RPG world, but because I'm bad at video games, my stat spread is horrendous, and I must now rely solely on my gear scores to get by. Can I still defeat the demon king and return home, even if I don't find any rare drops?"
