Oh and about Ano Natsu, Remon is more of a personification of the whole anime staff itself,it's my favorite part of Ano Natsu,the staff created a character just to do all the dirty work for them,they even give her the title of "director".And this is written by Kuroda,the guy can be quite a troll (the phantom requiem for a phantom thread has about 500 posts of debate over the anime original ending and the amount of raged it caused,I'm not exagerating)
Well I'm really having a hard time finding something available in english but there is Otoyomegatari and there is Satougashi no Dangan wa Uchinukenai which has Okada adaptation writen all over it. My Girl might also be something you'd want to check out though might suffer from comparaisons with Usagi Drop but I think it holds up quite well.
I'm not sure but I think you're familiar with Gunslinger Girl right?
I had a very strong one: Kiyoku Yawaku (one of the last Kodansha Manga Award award winners of the past few years not adapted by NoitaminA) and then noticed that while 10 volumes are out in France there's only 3 chapters scanlated in english.I just died a little inside.
I'll get back to you later
