Spears of Gungnir

Spears of Gungnir (グングニルの槍 Gunguniru no yari) is an execution featured in Danganronpa: Trigger Happy Havoc, with Mukuro Ikusaba being executed.

Sequence
After Mukuro (disguised as Junko Enoshima) violated one of the school rules by using violence towards the headmaster Monokuma, the sadistic bear immediately called upon the Spears of Gungnir, which emerged from the floor and impaled Mukuro all over her body.

This execution was used by the mastermind, Junko Enoshima, to once again taste the despair of killing someone that she loved.

Aftermath
In chapter 5, Junko used Mukuro's body as the "victim" of the fifth murder case in order to frame Kyoko Kirigiri, the Ultimate Detective, for murder, allowing the latter to be executed in the class trial.
