School Mode

School Mode is a bonus mode unlocked after beating Danganronpa: Trigger Happy Havoc for the PlayStation Vita and PC. Similar to Island Mode in Danganronpa 2: Goodbye Despair, the bonus mode serves as a dating sim, leading the player through a version of the main plot where there are no mutual killings.

Plot
The game starts out identically to the beginning of the main story, where Makoto Naegi enters the school and passes out. However, Makoto does not wake up in an empty classroom and instead wakes up at the sealed exit room along with some of the other students. After briefly discussing their situation, the group leaves towards the gym, where they meet with the rest of the students and Monokuma.

Once there, Monokuma makes an identical announcement as he does in the main story, however he declares that he is currently at a loss on what to do since he has forgotten to create "backups" for himself, and therefore cannot truly begin the group's "School Life". Although all the students are confused and reluctant to go along with Monokuma's words, he reminds the group that the door is sealed and that there is currently no way to leave. Monokuma then announces that in order to escape, the students must work together to create backups based on his specifications. After he leaves, the students all reluctantly agree to go along with Monokuma's orders since there was no telling what could happen if they refuse.

Gameplay
The player has 50 days to build the assigned backups for Monokuma. Using a special character management system, the player may assign students to gather materials for crafting the Monokuma backups or constructing tools, rest for the day, or clean the school. Gathering materials will slowly consume a student's energy, as well as reduce the cleanliness gauge. Resting a student will not provide any materials, but will prevent that student from reducing the cleanliness gauge. Cleaning the school will consume the student's energy, but will increase the cleanliness gauge. If the cleanliness gauge becomes empty, Monokuma will force the students to clean the entire school, which will waste a day.

Makoto will also be given one block of Free Time every day - two on the one day per week that Makoto and his classmates are allowed off - which can be spent in a similar way to the Main Game, either sleeping or spending time with any of his classmates. Using the Trip Tickets which are rewarded for completing Monokuma's backups, Makoto can take students to a location of his choosing based on the student's tastes in order to build his relationship with them.

Monokuma's Backups
Throughout School Mode, Monokuma will request the player to assemble backup Monokumas based on specified concepts, by gathering materials. Assembling these backup Monokumas rewards the player with Trip Tickets, which can be used to take classmates on a trip to locations within the school and bond with them.

Tools
Constructing tools can aid the player in collecting more materials or give the students more HP with which to explore the school.

Free Time
The player will be given one block of Free Time every day - two on the one day per week that Makoto and his classmates have off. The player can spend the block of Free Time with any one of Makoto's classmates, or sleep to skip that Free Time period.

Makoto will also have the option to go on trips with his classmates by spending the Trip Tickets received as a reward for completing Monokuma's spares. Each time Makooto takes a classmate to a location, and will be able to ask the classmate a question. Depending on how the classmate responds to the question, Makoto will earn zero, one half, or one full reputation heart on that student's report card. Getting all 10 hearts will unlock that student's ending.

Trigger Happy Heart
Trigger Happy Heart is a minigame in School mode. It uses mechanics used in the Rapid Fire Debate trial minigame in the main plot and is similar to the "Shot Through The Heart" minigame in the Island mode of Danganronpa 2. As Makoto builds his relationship with a character on Trips, Makoto will learn insights about the characters which can be used like truth bullets. Unlike the Rapid Fire Debate, there is no time limit on Trigger Happy Heart. The Trigger Happy Heart event occurs when Makoto gets close to full repution hearts on a classmate's report card. On the 51st day, if the player has completed Makoto's final spare, Makoto will be alone in the Gym with any characters that the player has earned full max reputation with. Talking to them will trigger the character's true Trigger Happy Heart event. If the player selects the correct answer, they will receive that character's special present - that character's underwear. This will also unlock a heart icon next to that character's picture's on subsequent playthroughs of School Mode.

Ending
After reaching the 51st day, if the player manages to build every backup assigned, the students will all gather around Monokuma, who yells at them for making a "backup" that doesn't even look like him. Out of anger and frustration, Monokuma decides to punish Makoto, saying that it would "motivate" the other students to do a better job next time, but the "backup" suddenly comes to life, introducing itself as Usami. After a small argument, Usami attacks Monokuma until he agrees to release the group and gives them the escape button before disappearing. Usami then thanks the group and says goodbye before mysteriously shutting down. Although many of the students are still confused, the group happily makes a small celebration as they are finally allowed to leave at last.

Trophies
A PSN Trophy is awarded for each character that the player achieves max friendship with. There are 17 trophies available in School Mode:
 * 1 bronze trophy for completing School Mode once
 * 1 silver for seeing every possibly School Mode ending
 * 14 bronze trophies for completing each classmate's report card
 * 1 gold for completing all report cards

Trivia

 * During the Monokuma Concepts segments, the blackboard scribbles, the pixels, and the names of the concepts are full of pop culture references:
 * Monokuma Casanova's name references Giacomo Casanova, and the pixel is dressed in the iconic white suit from Saturday Night Fever. The scribble on the board features Monokuma in a Minecraft scenario.
 * Monokuma Butler's pixel features a half-Monokuma, half-Roomba. The scribble on the board is a reference to Attack on Titan, with Monokuma as Titan and Makoto in Survey Corps uniform.
 * Monokuma Entertainment System's name references the Nintendo Entertainment System, and the pixel is a Monokuma Furby. The scribble on the blackboard features Monokuma as Anpanman.
 * Cooking Mamakuma's name references the game Cooking Mama.
 * The MoeMoekuma pixel features Monokuma dressed as Tinker Bell from Peter Pan.
 * The Monokumadult board scribble features Monokuma with a cape and Lightsaber, and girls being pushed away as if hit by a Kamehameha.
 * Warlockuma's board scribble features a magical girl dressed like Usami.
 * During the introduction and the end, Monokuma will break the fourth wall by referencing how he was destroyed during the Prologue and Chapter 5, and how certain events weren't supposed to happen until the sequel.
 * During Sayaka Maizono's ending, Makoto will have flashes of events from the main story involving him and Sayaka, who also seems to remember said events. This seems to imply that Sayaka really does have a limited amount of psychic ability.
