I think the title is self explanatory, I'm gonna try to my hand at a Konosuba book.
Konosuba is owned by Natsume Akatsuki
Warhammer is owned by Games Workshop
The people of Axel came together to rebuild their lives after the Skaven invasion. The harvest was able to get collected so won't be shortages now that Winter's here. Many were saved, many were lost, and some will never be the same again. The capital also brought relief supplies as well and helped out with the reconstruction. Now you were walking towards the black smith shop. Many people waved to you. You not only an Imperial Knight but also a champion of Sigmar so you'd become quite the celebrity due to your knowledge and experience in defeating the Skaven. You open the door and enter the shop. It's stocked with swords, shields, armor, and a new stock Springfield rifles.
Smith: Well look who it is. Axel's Ranger.
Y/N: Hey man, how's business?
Smith: Back to normal to say the least.
Then you hear a crash coming from the workshop.
Y/N: Hard at work is she?
Smith: Yep, head on in.
You open the door to the workshop.
Y/N: Anyone back here?
From the shadows glowing yellow watching you and the you're tackled to the ground with it's eyes looking straight at yours with very soft mounds pressed your chest
???: Well hello Sir Y/N.~
Y/N: We're not in Altdorf you don't have to call me that......Now can you please get off Mei?

This is Mei Hastume, a socially awkward inventor from the Empire that you met during the reconstruction. Just like you and Kazuma she was reincarnated from another world after dying in an accident involving one of her inventions. But according to her she came from version of Earth where most people have unique abilities called "Quirks" you and Kazuma both thought that sounded like the plot to a superhero comic. You bumped into her one day she dropped a bunch of blueprints. As you helped her pick up the blueprints you admired some her designs and she got examine your rifle and she said she could help you. So you introduced her to the black smith and he offered her a job. Now she was letting back up.
Y/N: So how's it going?
Mei: It's been wonderful! I have so much more freedom here that stuffy Imperial Engineers School. They were all like, "Oh no that's too dangerous!" or "That simply unorthodox" The teachers and students call me "Volker von Meinkopt's granddaughter." So what of he took me in and taught me engineering in this world! I'm still my own person dammit! Never mind I'm the youngest Master Engineer the Empire's ever had!
Y/N: As far I know Meinkopt invented those repeater guns hanging on your wall right there.
