Plot
Makoto Naegi wakes up and finds that he and 14 other students are trapped in Hope's Peak Academy, and introduces himself to the other students. The self-proclaimed Headmaster of the Academy, a robot bear named Monokuma, informs the students about the Killing School Life they're forced to participate in.

Later that same day Makoto finds a murder victim in his shower room: His classmate Yasuhiro Hagakure, with a knife in his stomach. This is also identical to how Sayaka Maizono was murdered in the first game.

Makoto begins to investigate in his room and talk to his classmates in order to gather clues and evidence. Not too much later, Monokuma announces that they all need to meet up for the Class Trial in order to solve who murdered Yasuhiro's.

Makoto got 5 truth bullets in the investigation. It's pointed out how clean the room is as the killer must of used a lint roller, and on the aforementioned lint roller is potato chip grease. As in Sayaka's murder, also used a kitchen knife in order to murder Yasuhiro.

Trivia

 * There's a possibility that Danganronpa: Trigger Happy Havoc demo was originally going to have an English language localization, as there is a clip recorded by Monokuma's English language voice actor Brian Beacock featured at the end of the demo. The line is: "Alright, That's it! I can't let you go this any further! Cause this is just the demo!". This line was later reused in Cyber Danganronpa VR: The Class Trial.
 * Yasuhiro is also the victim in New Danganronpa V3 - Trial Version.
