Here's why:
* Subjectivity of sadness: What one person finds heartbreaking, another might find merely tragic or even entertaining.
* Variety of sad manga: There are countless manga out there exploring themes of loss, grief, sacrifice, and other elements that evoke sadness. Some examples include:
* A Silent Voice: Explores themes of bullying, redemption, and regret with a focus on emotional impact.
* Your Lie in April: A poignant story about music, loss, and the power of connection.
* Fruits Basket: Deals with family, trauma, and healing in a deeply emotional way.
* Death Note's focus: While Death Note certainly has sad moments, its main focus is on the psychological thriller and the moral dilemmas surrounding the power of the Death Note. It's less about evoking pure sadness and more about exploring the consequences of wielding ultimate power.
Ultimately, whether Death Note is the "saddest" manga for you is a personal judgment. If you find the loss of characters, the tragic consequences of Light's actions, or the overall themes of justice and morality deeply affecting, then it might be considered "sad" for you.
However, there are many other manga that explore sadness and emotional depth in different ways, so the title of "saddest" is subjective and open to interpretation.
