The community had two big reactions when the anime adaptation Kimi no Suizou wo Tabetai (I Want to Eat Your Pancreas) was announced: this is going to be a really sad anime movie and are other anime or manga like it?
Entertainment about terminal illness is a taboo, largely because it’s something that affects people on a personal level. You run the risk of trivializing an illness if your story is bad, but it can provide a huge emotional punch if done right. These anime, manga, and light novels are good examples of how the medium can handle terminal illness.
Keep in mind that “anime magic” is used at times to prevent a death from terminal illness anime. While the ending may come off as cheesy, the rest of the journey will be a cry fest.
