The Tragedy

The World's Most Despair Inducing Incident is a major event in the Dangan Ronpa (series), and happens before and still currently is around the Dangan Ronpa timeline. The beginning is described as a form of social unrest which culminated in total war between the participants.

Pre-Incident
Shortly after the opening of Hope's Peak Academy for the reserve course. Normal students without excelling in a subject but willing to pay high fees for the prestige school. Reserve course student Hajime Hinata applied for an experiment for artificial augmentation renaming himself Izuru Kamukura and gaining the Title of Super High-School Level Hope.

World's Most Despair Inducing Incident
Junko Enoshima, in her desire do spread despair, forced the Student Council of Hope's Peak into the first known mutual-killing game, killing all but Izuru Kamukura and the heavily wounded student council president Soushun Murasame. This was broadcast to the reserve course resulting in unrest for spending most of the schools funds for "creating" murderers. The reserve course then rebelled and protested being led and agitated from the shadows by Enoshima and her organisation Super High-School Level Despair. The social unrest soon became a movement turning more and more violent until violence and death became a normal part of society. Hope's Peak Academy then decided to lock itself up starting the events of the first game.

Description In-Game
The biggest and most despair inducing incident in all of Hope's Peak Academy ’s history” was only the beginning to what would be the word's end. The biggest and most despair inducing incident in all of Hope's Peak Academy’s history ( the cover-up of ASDS caused the reserve course students to rebel…

At first, it was optimistically thought that everything would calm down soon, but the situation worsened and quickened its pace. The movement happened on the Internet, and formed a community of its own.

Soon, not just students were involved, but came to include people of various races and nationalities in its development and spread off the internet and into real life.

At the beginning of the movement, it involved demonstrations regarding social issues, but as it spread through the world, its abnormality began to show. At some point in time, the motives and modus operandi changed, and left behind only meaningless destruction and violence.

Strong people killed weak people…

Weak people murdered even weaker people…

Weak people formed factions and lynched strong people

As the violence and death spread, people became desensitized. As if time had gone backwards, people took death to become a certainty. The media reports overflowed with death, and people ate as they watched. By the time the world had noticed the abnormality, it was already too late.

The overpowering “despair” became a huge wave that swallowed up the world in the blink of one’s eye…

Soon, terrorists and coup d’etats sprang up and caused the despair that is war. It wasn’t war that happened due to the clash of ideals, religion or profits…It was just war.

Pure war.

Therefore, no way to solve the problem was found. However…how did what was originally a students’ movement develop into such a despair-worthy situation? This was because of…the existence of “a certain group of people”.

It revolved around the “certain student” who led Hope's Peak Academy to its destruction; a group called “Super High School Level Despair”.

Their talents, recognized by Hope's Peak Academy, were used not “for the sake of causing hope for humanity”…They used their talents “for the sake of causing despair for humanity”. Those who held great power brainwashed ordinary citizens to spread despair…

Those who had talent with computers created software to spread despair…

Those who had great influence over people created new ideals to spread despair.

This is how “the biggest and most despair inducing incident in all human history” was produced. Indeed, as long as “Super High School Level Despair” exists, this despair will not end…

“The biggest and most despair inducing incident in all human history” will not end…
