any manga recommandations like wealcome to the nhk or yotsuba? (yeah i find yotsuba to be really depressive in some way, behind the chill and happy faces and all the ahah eheh)
literally anything by oshimi. he has this special way of writing that makes you feel very uncomfortable and quite dreadful at times. he's great. I personally recommend chi no wadachi and aku no hana from above post. https://myanimelist.net/people/6579/Shuuzou_Oshimi
takopis original sin is almost as depressing as punpun i know you're not asking for anime recs but the anime also has a really nice artstyle and i liked it enough to rewatch it several times.
