After School Lesson

After School Lesson (補習 hoshū; lit. Detention) is an execution in Danganronpa: Trigger Happy Havoc, with Makoto Naegi (in the good ending) or Kyoko Kirigiri (in the bad ending) being executed.

Makoto's Version
Makoto is in a room filled with school desks. In the center is a large conveyor belt where his desk is located. As he sits there, it goes backwards towards the end of the room. Behind him at the end of the conveyor belt is a large block resembling a trash compactor that slams down every few seconds intending to crush whatever is underneath. Above is a television showing Monokuma's face on it. As his desk moves backwards, Monokuma dressed as a teacher appears in front of him and attempts to teach him a lesson in class (specifically sex ed), while Makoto constantly turns his gaze behind him, nervously watching the compactor. However, as luck would have it, just as his desk is about to go under the compactor, at the last second, the Monokuma on the television is replaced with Alter Ego for a moment. The compactor stops just as Makoto is about to be crushed flat. The conveyor belt keeps moving on and a door in the floor opens. Makoto and the desk then fall backwards through the very large and deep hole in the floor while Monokuma looks on in panic. As he falls, the white board has changed to "yet again to, The end of life, showing stabbing, drowning, burning, etc."

This ending is the good end route of the chapter, where it would lead to the true ending of the game as well. The ending can be achieved by not calling out Kyoko's lie in the fifth trial. Once it is achieved and the execution ends, the sixth and final chapter of the game is unlocked, in which the last trial takes place, where the remaining students try and solve the mystery of the academy itself.

Kyoko's Version
Kyoko is in a room filled with school desks. In the center is a large conveyor belt where her desk is located. As she sits there, it goes backwards towards the end of the room. Behind her at the end of the conveyor belt is a large block resembling a trash compactor that slams down every few seconds, intending to crush whatever is underneath. Above is a television showing Monokuma's face on it. As her desk moves backwards, Monokuma dressed as a teacher appears in front of her and attempts to teach her a lesson in class, while Kyoko constantly turns her gaze behind her, nervously watching the compactor. Eventually, her desk goes under the compactor, and Kyoko is crushed flat.

This ending is the bad end route in the game, where the surviving students despairingly spend the rest of their lives in the academy. The ending can be achieved by calling out Kyoko's lie in the fifth trial. Once it is achieved and the execution ends, the player can replay the trial again, starting from Makoto's last decision, and choose to not call out Kyoko's lie.

Trivia

 * Both the fifth trial and this execution were held on Wednesday, April 1st as written in the original Japanese's execution title.
 * This is the only execution with both a good and a bad route.
 * In both execution versions, Monokuma first taught Makoto/Kyoko about how the conveyor belt and the large block resembling a trash compactor works which written on the blackboard. However, in the next scene, Monokuma taught Makoto/Kyoko about human reproduction which is also written on the same blackboard.
 * In DISTRUST, Sayaka Maizono and Leon Kuwata were the ones who were to face this execution.
