Moment of appreciation please for Hotondo Shindeiru; this manga is in my opinion the gold standard when it comes to Isekai manga.
A lesser mangaka might have just written it as a quirky parody of the genre, rather than giving the characters such depth and taking the plot into unexpected places and working with tropes and cliches to ultimately subvert them, taking the manga into fresh ground rarely covered by Isekai. Being able to keep the humour going at the same time as dramatic events without it detracting from them or seeming forced is something very few authors can pull off as well too. Not only is the writing great, but the artwork is ridiculously detailed, expressive and beautiful too (ironic considering Uncle's countenance).
I have been reading Manga since the 90s and this is definitely one of the best there has ever been.
