You know the drill.

In a setting filled with magic, the MC is a member of the bureaucracy in charge of cataloging different types of spells, creatures, phenomenon's, and spirits. He lives a respectable life for the most part and in his free time he writes anonymous articles for a magazine that gives speculation advice regarding the mage arena matches, where he has a good reputation, save for the fact that he always bets against the undefeated champion of the arena: an Archmage who's a Divine Summoner.
In truth, he always wanted to fight in the arena himself, but could never muster the mana internally, channel it from the natural world, or make any contracts, on top of never being able to choose a school of magic that 'fit'. However, one day he's accosted by the "Demon-blooded' Archmage, a woman with holes in her fingers from which black ichor leaks that she can draw sigils with, who's notorious for churning through disciples. She found him through his articles and offers to teach him in exchange for paying a price later, which he immediately accepts, seeing his chance.
Later it's revealed by the demon-blooded that the reason he never found success is that he was afraid to commit to one magic, because it could've been the 'wrong' choice, thus he never realized any deeper skill. She makes him swear an oath to one school of magic, forsaking every other if he wishes to still be her student. Having discovered his love for fighting and winning, he makes the obvious choice, the strongest magic: Divine Summoning. But since he's not beloved by angels, he has to bind them in some way, so he permanently sacrifices some of his mana to create chains and nails that enslave the divine beings he summons to his will. The series would follow his path to the top, while magical incidents and wizard-like intrigue go on in the background.
It'd be titled "Crucifier" as a reference to what he does to angels and how he's crucifying his passions.

****[Super Sentai Tentacle Armor]*****
A modern world where women and only women gain magical powers while pregnant, as a natural feature of the human condition. These women are frequently hired by various industries to use their powers to help the work. There are also "Professionally Pregnant" women who get pregnant regularly in order to be professional mage working-women. The purpose of all this in this setting is so pregnancy is viewed as a venerable thing in this world. Men fucking these pregnant bellies gives them a temporary physical boost and also heals them. The closer a pregnancy gets to fruition, the more powerful she becomes. Though it isn't too substantial a difference.

There are also fantasy beasts in this world, but none particularly powerful. No dragons beyond maybe dog sized lizards that are mildly magical if at all. Tentacles are also small fry that need other species' wombs to procreate, but hardly ever prey on humans beyond children occasionally and adults rarely. The handful of times a human is impregnated, they just gain magic powers and kill the tentacles. The tentacles are too dumb to learn from this.
One calamitous day a crack in space happens which causes an invasion of eldritch horrors from a demon realm. They are beings of pure malice that love bad emotions and suffering. Conversely they are harmed by pleasure, good emotions, and most of all: the indomitable human spirit. These beings spread corruption and mutating effects wherever they go. They turn the animals of the land and the corpses of humans into vicious beasts that attack humanity with them. Note however than none of these beings or animals rape humans. They just slaughter them.
The tentacles are where the sexual aspect comes in.

>>279793269
There was a genius scientist girl who studied tentacles. She was also a pervert who let them fuck and impregnate her, who then studied the effects. She noticed that they were highly adaptable and got marginally more intelligent when birthed by humans, about as intelligent as crows. Her lab gets attacked by horrors and her security guard, who is in love with her, dies trying to protect her but fails and she perishes too. She was pregnant with one of her experiments. The corrupting energy washes over all the animals and tentacles in her lab an mutates them as one would expect. They too normally would reanimate as zombies but the love filled circumstances of their death protects their corpses.
The magical nature of this world's pregnancy, the corrupting miasma, the tentacles' adaptable nature, and the human spirit and love all combine into that tentacle baby in her belly and transform it under the influence of one potent concept: the indomitable human spirit. The evil of the miasma gets cucked and transformed to good. The demons then leave and after some time the tentacle baby's power in concert with pregnancy magic actually revives the girl. She is filled with vigor and spirit and can sense and FEEL the nature of the baby inside her. It soon after is born and it is extremely intelligent with an inherently benevolent character and it can transform fluidly and can take on a form resembling that of the security guard, though it doesn't know this immediately.

She raises it and some time later with it (henceforth "Tentacle Prime") forms an Anti-Demon Sentai Organization. It works like Symphogear except instead of music it's the power of motherhood.
They discover the nature of his birth and research his abilities. Pregnancies with him are much more powerful and the nature of the magic is far more versatile. Even more powerful however are "Self Genesis" pregnancies, the type of pregnancy on which the Tentacle Maiden Corps is based

>>279793289
Tentacle Prime and his dozens of offspring with Scientist Girl are capable of, if they choose, melting down into a semen-slime on ejaculation and rushing into the wombs of their wielders and impregnating the girls with themselves. It take mere hours for the pregnancy to progress to full development and power (later one of the Battle Maidens awakens a power to accelerate it for her team even further).
Normal pregnant mages (henceforth simply "mages") are useful militarily and are lethal but are just as fragile as real pregnant women. Corps women are different. Their "Pilots" have the ability to strengthen their bodies when inside them and form magical armor around them. The tentacles can pilot their "Cradles'" bodies from the inside although in practice they actually meld wills and empower each other with fighting spirit, the glory of humanity ('Battle Tentacles" are by-law classed as full humans), and "the magical engine of motherhood". Though whenever a Cradle is knocked out they can always take over. After battle the girls give orgasmic birth to their "Husband-Sons" and the whole process starts over. Battle Tentacles have distinct quirky personalities and can adopt humanoid forms and spend most of their off time fucking their "Mother-Wives" or having romantic dates. Even their battle training involves sex.

All their conversations and battles are filled with cheesy inspirational one liners about the power of friendship and love (and motherhood). They are also empowered by normal human couples all over the world having pregnant sex, with some help from signal boosting Sentai tech. When big battles against the Demons happens, couples all over the world have enthusiastic pregnant sex (all stages of pregnancy work) and send their heroes their energy, like the Spirit Bomb. At HQ cute pregnant operator girls in purposefully extra-sexy military uniforms fuck their engineer boyfriends and do the same.
All very hype and hotblooded kek.

how about you faggots get to drawing instead of spitballing?

Writing and drawing are separate skills and nobody here has either

It's a writing thread, but I gave it a shot.

MC gets isekaid but whenever he falls asleep that entire world and everyone in it will die and he gets sent to the next isekai world

Two groups of people get sent to a fantasy world with no explanation, none of them even died, one group is lead by a Haruhi Suzumiya type that wants adventure, and is genre savvy about isekai anime and RPGs. THe other group is folks who hate HATE isekai and anime in general and them being in this world is hell for them. The anime would be a satire and criticism of the genre with one part of if it seen from the perspective of people who hate anime and another showing how flawed these stories are. The Haruhi type butts heads with the anime haters constantly, and calls them "scrooges" for their attitudes toward the genre. Each group would recognize when something is about to start, like a girl running with bread in her mouth, the group lead by a Haruhi type would try to reenact Evangelion and the other gets away. Not dealing with that shit. Sometimes there would be fourth wall breaking from the Haurhi type, which the anime haters would be like, "there's an audience?" to which they would yell "HELP! SAVE US FROM THESE STUPID ANIME SHOWS!" or "CHANGE THE CHANNEL NOW!"

>>279793549
I can make logos, does that count?

>>279797317
Another thing I forgot to add, each groups are able to predict when something romantic or perverted would trigger, or a "flag", which the Haruhi wannabe tries to initiate or inform the others, like when something out of a harem or a yuri/yaoi would happen, the anime haters would just run away really fast with a caption crawling below the screen reading: "They dodged a bullet". No way they are going through any of that. Heck, if a love potion is present, or even an Ataru or Happosai type character, the anime haters panic and vanish in a huff. At least they didn't get harassed!

>>279797317
I like how you conflate hating isekai with hating anime in general. Very telling.

All I have to offer is - the smaller and tighter a catgirl's skimpy oufit is, the larger the bazooka/ anti-aircraft cannon, missile launcher etc, they can produce from their cleavage.

MC attempts an impossible jailbreak by assuming a guard's identity after finding his mysteriously disposed of corpse. Can he keep up the charade and escape? He's accompanied by the guard's ghost who despairs over how the MC basically ruins his reputation during the impersonation. There is magic in the setting which primarily functions as scaffolding for puzzle quandaries for the MC to snake his way out of.

Here's one: the typical MC of a harem anime runs into the typical FMC of a reverse harem anime by accident; both clumsy, both awkward, both timid and both quirky, they realize they have too much in common that they stick together and eventually they fall for each other and confess their love for each other at the same time in the most clumsy way, they are now a couple. Their respected harems however will not stand for it that they do everything they can to separate them. Most of the the story revolves the people around them, outsiders wondering why they pine over such bland folks they would ask the girls who are every archetype of a harem, a tomboy, a loli, an ojou, a glasses girl and a tsundere why bother with a bland dorky guy that seems too boyish when there are other hunks and better looking guys out there in the same breath they ask the guys who are every archetype of a reverse harem the prince type, a bad boy, a glasses guy, tragic emo, the shota and the athlete why bother with such a plain girl who isn't sexy and seems kiddie like when there better looking babes with big titties out there, and they fall on deaf ears. The leads act more like catalysts for the episode as the two harems react with anger as each scheme to break them apart and take them back bur both are oblivious to their respected harems, even outsiders stir things up with misunderstandings similar to the ones in Love Hina, Ranma and School Rumble.

A romantic comedy remake of these femdom hentai:

https://nhentai.net/g/64662/
https://nhentai.net/g/34182/

Instead of sex, two of the girls, the younger sister and the dark skinned tomboy she got to have sex with her brother realized they wanted romance this whole time. A month after the brother recovers from the intense first sex he had with the rough tomboy, she sees him again only she wants to go on a regular date with him but it's her first time and sadly his too so it is a very awkward one. Meanwhile the younger sister decides to do the same with the first year student that she and her friends use as a toy, but sense being used as a sex toy is all he knows, she decides to "educate" him about romance kind of like she is molding him or grooming him in a "Reverse Genji Hikaru" way, because she feels responsible for the way he is and she blames herself that he doesn't know anything about romance. It's now a strange romcom about two girls trying to give up their femdom ways and find real romance with the guys they played with for so long, but they find it hard to control their urges, and it looks awkward to outsiders who witness them since they are the ones taking the lead, the tomboy looks more like a "boyfriend with boobs and vagina" and the younger sister looks like a shotacon grooming a boy since her junior looks way too young.
