'Ello. Had to do a bit of searching and I've realized that to find some SW, you gotta find some SM manga. Thankfully, I managed to find a few. More in the Mahua and Manwha scene than anything it seems, but the hunt is on.
My 5cm Life is about a dude who wakes up at, you guessed it, 5 centimeters tall (aka 2-inches tall) in his own apartment and finds himself trying to survive at such a tiny size when the world at large is out to get you. Turns out, his female landlord was also affected by whatever shrunk them, and the two try to figure out what exactly happened and how to get back to normal size.
Btw, she's a badass.
Chiisako No Niwa is an anthology of stories a la The Borrowers-style the encounter of tiny people with normal sized humans. Well, I guess moreso
koropokkuru in this case. Some people can see them, some can't. Chapter 3 and a bit of chapter 5 are the ones where the SW are in it, but the whole story is rather beautiful and worth the read.
I Married the Male Lead's Dad to is another one of those Korean "warped into an isekai book" stories where a woman finds herself married/engaged/in-concubined/etc. with... well, it's in the title. In any case, Chapter 62 to 65, after some mishap with mixed potions, she's shrunken to the size of a doll and remains shrunk for a couple more chapters until grown back to normal the latter half of Chapter 65.
Omniscient Reader is about a man who, after the world has been thrown into an apocalyptic round of survival games and scenarios, has the upper-hand after knowing exactly what's going on and how to make it through, thanks to being the one who read the book that would soon foretell the events going on; with the contents of the book being brought into reality. In my opinion, definitely worth the read. In any case, from chapter 125 of the manwha, the main characters and a select few are thrown into a scenario where they are sent to a world where everyone and everything is at a smaller scale and are tasked with wiping out the tiny inhabitants. Those who refuse the call are penalized by being shrunken down to the size of the inhabitants, which includes the MC and his gang. Quite a few SW sprinkled in here and there, just like a bit of SM.
And last (for now), but not least, is
Umineko No Naku Koro Ni: Episode X. Umineko is a rather convoluted (and I truly mean that in the most flattering case possible) mystery, supernatural thriller taking place in the 1980s where a wealthy family gather at their patriarch's island to dispute the distribution of his wealth. Things get rather muddled when the legend of a witch, the true owner of the gold, and her epithat must be solved, including the murder of said family members and all inhabitants of the island. Our main character, among the murdered, must solve these seemingly impossible murders while trying to denounce that magic wasn't involved, and... well, let's just say that things are very,
very complicated. In both the metaphysical sense and in-story events. You really can't properly summarize it without reading it.
This story is none of that.
This is simply a silly crossover with the author's previous work, Higurashi no naku koro ni (another rather interesting supernatural murder-mystery thriller where there's a lot more than meets the eye), where things are weird and that's that. Either way, Jessica gets shrunk for whatever reason and that meets the quota for SW.
And not much pictures either. Just all words.
