7 Banana Fish
Based on the Original Manga by Akimi Yoshida, Produced by MAPPA

When Eiji interviews Ash about his experiences, the pair begin to work together to learn more about a strange, dangerous drug known by the nickname "banana fish," forming an unlikely connection in the process.
The series is dark, delving into topics like crime, sexual abuse, the drug trade, and psychological struggles. While most of the series has a somber, distressing tone, one of the most upsetting facets of Banana Fish is its tragic ending.

6 Demon Slayer
Based on the Original Manga by Koyoharu Gotouge, Produced by Ufotable

The war between humanity and demons unfortunately leads to many casualties, and demons and Hashira alike lose their lives throughout the anime. To make circumstances even more discouraging, many demons did not want to become an evil creature, but Lord Muzan transformed them against their will. This additional layer of horror and sorrow makes Demon Slayer even sadder, and though the series does intersperse moments of comic relief and Tanjiro's optimistic outlook, it is hard not to feel unhappy when considering the dreadful events the characters experience every day.
