Danganronpa: Trigger Happy Havoc IF

Danganronpa: Trigger Happy Havoc IF: The Button of Hope and the Tragic Warriors of Despair is a light novel written by Ryōgo Narita. It explores what would have happened if Makoto Naegi had received the Escape Button from the MonoMono Machine in the beginning of the game, which helps him slowly regain his memories. It is unlocked after completing Danganronpa 2: Goodbye Despair.

Chapter 1
Makoto receives a strange button from the MonoMono Machine, presses it, and receives a strange electric shock that causes him to have a terrible headache. As he's lying in bed thinking about how to escape, Sayaka Maizono knocks on his door, planning to start her plot for murdering Leon Kuwata. Unfortunately for Sayaka, Makoto collapses and loses consciousness during their conversation.

Makoto wakes up in the infirmary with Mukuro Ikusaba (disguised as Junko Enoshima). The two converse, and Makoto has a feeling, at the time inexplicable to him, that he's talking to someone other than Junko, but dismisses the feeling as just a symptom of his mysterious illness.

The students are all called to the cafeteria and Mukuro (as Junko) challenges Monokuma.

Just as the Spears of Gungnir are being released, Makoto yells for Mukuro to get out of the way while running towards her. She is so surprised at being called by her real name that she steps back, and Makoto is stabbed by the spears instead.

Chapter 2
The point-of-view switches to Mukuro as she reels from the shock of Junko's attempt on her life. Makoto weakly asks her why she's dressed up as Junko, but quickly passes out due to blood loss. The other students begin to question whether Mukuro really had committed an act of violence against the headmaster.

Junko switches gears and has Monokuma say that he has been hacked by someone from the outside world. She (as Monokuma) claims that Mukuro is a terrorist, and the cause of the sadistic killing game. The students are confused at first, but quickly fall for Junko's lies, and turn on Mukuro.

Because she's not very good at manipulating people and Makoto is near death, Mukuro grabs Makoto and attempts to fight her way out of the gym. She takes on Sakura Ogami, but Sakura turns out to be the better warrior. Realizing that she can't beat Sakura, Mukuro intentionally triggers Toko Fukawa's personality change into Genocide Jack. Jack distracts the students, allowing Mukuro to leave the gym, carrying Makoto, so she can treat his wounds, as Kyoko Kirigiri silently observes.

Chapter 3
Mukuro carries Makoto on her back as she runs to the infirmary to treat his wounds and save his life. She also ponders the fact that Junko just betrayed and nearly killed her.

The other students in the gymnasium face off against the serial killer Genocide Jack, and she starts a fight with Sakura.

Back in the infirmary, Mukuro uses the first aid equipment to stop Makoto's bleeding. She's in the process of performing a blood transfusion when Monokuma appears behind her.

As always, Junko uses her skills in manipulation to confuse and distract Mukuro from the correct course of actions, in an attempt to prevent Mukuro from saving Makoto's life. Junko says "I love you" to Mukuro, and in that moment Mukuro realizes that Junko is breaking all connections between them.

Chapter 4
More than ten minutes pass, and Jack is tied and locked up in her room. Half of the students stay behind to keep watch over her, while the other half search through the school building for Mukuro and Makoto. When they arrived at the infirmary, Kyoko finds a nonfunctioning Monokuma with a hole through his chest and the remains of a security camera.

Kyoko tells Chihiro Fujisaki to stay with her in the infirmary to search for clues, because he's the only one who can investigate Monokuma's body, and the others leave the infirmary. She tells Chihiro to use his laptop microphone and voice recording function, because she wants to record everything that they will hear from this point. Then she says that she has found Makoto, and he was in a bed that was in a blind spot from the doors, with a blood pack that was hidden beside the bed providing him a transfusion.

Kyoko also finds Mukuro's hiding place, so she asks Mukuro to explain her side of the story. Mukuro tells her that Kyoko is the Ultimate Detective and the rest of the story, and leaves the room. Finally, Chihiro finds in Monokuma's control system that he is the creator of the program.
