Chiaki is forced into a dungeon maze full of dangerous traps. Forced to escape to reunite with her friends, she kept moving through the halls but had activated a hidden switch on the floor, allowing a spike to impale her foot. Not giving up on hope, Chiaki is then fired with metal balls that injures her right eye and arm. As Junko Enoshima, who watches her through cameras in the dungeon, starts a countdown, Chiaki desperately tries to limp to safety only to be speared in the knee. Junko proceeds to mockingly state that she has a despairingly bad temper. At the end of the maze is a large door marked "GOAL", behind which stood Chisa Yukizome and her classmates. Upon Chiaki opening the door, she saw her classmates and teacher happily waiting for her. Chisa reaches out for Chiaki but she only happens to be an illusion; instead a spear fired and went through Chiaki's body. Simultaneously a bed of spikes appear around her, catching her as she fell.
Unlike other executions, it does not end in her immediate death, allowing Izuru Kamukura to talk to her briefly. It is also more eventful and tortures her a bit more before she dies.
- Unlike other formal executions, only its broadcast is "hosted" by a Monokuma as a stuffed bear; Junko herself directed the execution through video screens.
- This is by far the longest execution in the series, taking up over half the episode in which it takes place. Comparatively, most other executions last around 2 minutes maximum.
- Chronologically, this is the first formal execution in the Danganronpa series.
- Interestingly, the execution of Chiaki's AI counterpart happens to be the last formal execution in the Hope's Peak Academy Arc.
- Chiaki's death in Despair Arc is very similar to Mukuro's death in Danganronpa: Trigger Happy Havoc: being suddenly impaled by dozens of spears. The deaths also double as acts of betrayal from those who were closest to them (Junko, in Mukuro's case, and Chisa, in Chiaki's case).
- It should also be noted that her AI counterpart in the Super Danganronpa 2: Sayonara Zetsubō Gakuen THE STAGE (2015) is executed by spear impalement as well.
