the anime for oniisama e is way more popular so i think a lot of people would be curious as to whats better: manga or anime. as a person whos checked out both i will say without spoilers to those curious that i recommend watching the anime. manga is definitely used as a source with most chapters being practically identical to anime events but anime is much more fleshed out. it shows us the characters emotions in particular moments makes things more dramatic and makes the story overall better. yes not everything that happens in anime is the same as the manga but i think the changes that are made are tolerable and sometimes are for the better. now the spoilerfree part is over so ill say which parts i enjoyed more in the anime: now what i enjoyed more in the manga: theres another big change but i am not sure what to think about it: overall do i think oniisama e manga is worth reading? sure but dont do it instead of anime. you wont get attached to the characters the same way and theyre really fun i promise. for those who want to look into the manga after watching the anime i say go for it since its pretty short and the art is really good. but yeah the problematic + heterosexual things that were in the anime remained here and sometimes even worse which i mentioned. still oniisama e is dear to me despite all of its flaws.
