I found this after typing "reverse harem hentai" on google images. I´d like to know how this doujinshi is called and where can i find it, preferably in english. Any help is much appreciated and will contribute to my research
It seems like a parody or the actual manga of Sekai de Ichiban Tsuyoku Naritai!, which is only translated to chapter 2 but available RAW until vol 5 and also has an anime.
Confirmed, it was the real manga, chapter 2.
