Development
Creator Kazutaka Kodako pitched a television idea to Spick Chunsoft studios where the premise was 15 teenagers will battle out in order to win a grand prize with strategic and social ability. The idea was developed in a spam of 2 years which is what gave the show a cool aspect and appeal to teenagers. A short prototype promo was shot and it almost flopped to the point where the whole show was almost scrapped. Despite this, Spike Chunsoft studios worked with other key studios to help develop the show what its now known as Danganronpa - Trigger Happy Havoc

Casting
The cast was originally going to have 15 contestants but this was ultimately scrapped in favor of having 1 more contestant for a twist making the final cast size at 16. The cast process was long as they had to find people with special abilities and personalities that can help make the cast very diverse and entertaining at the same time. More than 100 applicants applied to be on the show.

Twists

 * Sisters: For the first time in the series, a pair of sisters entered the game but kept their relationship a secret during the first week. Sisters Junko Enoshima and Mukuro Ikusaba entered the game as individuals giving them a slight advantage. However, the twist was later revealed to the contestants after Mukuro Ikusaba was Eliminated.
 * Love From Home: In the first week, many of the contestants were already home sick. In response, Monokuma sent a task to all of the contestants to solve a series of puzzles located around the first floor of the school in order to win letters and gifts from loved ones back home. All of the contestants were able to win the reward winning assortments from family members and a feast to celebrate their accomplishment.
 * Secrets: In Week 3, Monokuma told every single contestant that whoever was the first 4 people to drop out in the HOH competition would have to reveal one main secret of theirs to all of the other contestants or else they would be a Have-Not for the rest of the week. Contestants Chihiro, Mondo, Makoto, and Toko were the first 4 to drop and had to reveal a personal secret about themselves. For doing this, they were given each a slop pass making them "Haves" for the week.
 * Fake Money: In Week 7, Monokuma placed fake cash bundles in front of the gym to see who would take the most and which would not. Aoi went on to take the least money giving her a slop pass for the week. Celestia went on to take the most money from the bundle and was deemed a Have-Not for the week. However, Celestia ended up returning the fake money in Week 8 and because of her honesty, Monokuma gave her a slop pass for the week making her a "Have"
 * Saboteur: In Week 9, the public voted for someone to become a saboteur for the week, Makoto was ultimately chosen and his job was to cause as much chaos in the school without being caught. Also with that, Makoto was also able to recruit a pass Eliminated contestant to help aide him in his task, he recruited Sakura and went on to cause many pranks and messes for a whole day. For completing his task, Makoto was given a slop immunity pass.
 * Second Floor: In Week 11, the gates blocking the second floor stairway were open allowing the Final 6 to explore the second floor, the second floor would later be used for the HOH and POV competition for that week.
 * Mastermind: The mastermind twist was the key twist of season 1. Many fun moments that came from the season was because of this twist. For the first time ever, the host was a hidden contestant amongst the cast of 16 players. With many speculation and many doubt, it was later revealed that Junko Enoshima, who was Eliminated in 8th Place, was the secret mastermind and had been masterminding the entire game. Because she was the mastermind and was on the jury, her vote was decided by the audience. She voted for Kyoko who didn't win against Makoto.
