I Transmigrated to Another World and Became a Succubus

[Transmigration + transformation + queen + extraordinary otherworld + science leads to godhood] This world is full of extraordinary powers in all their variety: witches, swordsmen, mages, alchemists, steampunk, demon hunters, and clerical priests. It is home to strange, intelligent races: humans, half-demons, goblins, orcs, dwarves, yordles, giants, beastfolk, dragons, and the undead. A gifted engineering student from Earth transmigrates into the body of a mature woman with a succubus physique. Let these natives of another world see what weapons made with Earth's technology can do! Under the shotgun, all life is equal! A nuclear-peace forbidden spell? I advise you all to calm down. You want to use your god to intimidate me? Ask your goddess how many divisions she commands!
