TL;DR: Adventure of Cute Shota MC with Onee-sans that includes misunderstandings and comedy. You can read it >here<
I read it this morning... It's surprisingly funny, if it stay this good all along it will definitively be a regular read.
I thought it would be a usual japanese isekai it has a good premise I also like stories with misunderstandings
A little googling and.... http://lndb.info/light_novel/Tatoeb..._no_Machi_de_Kurasu_Youna_Monogatari/vol/8959 Well that kinda sucks the manga is based on the LN. LN was released last year of Feb. 2017 while the manga adaptation Sep. 2017.
