Strand of Agony

 is an execution in Danganronpa V3: Killing Harmony, with Kirumi Tojo being executed, and Monosuke being destroyed in the process.

Sequence
Kirumi is being chased through a hallway by a group of protesters, until being blocked off by another group of protesters. She wonders what to do until she sees a vine with thorns drop down from the ceiling. The vine goes through a couple of spiderwebs. Kirumi grabs on and climbs up, due to it being the only way out, piercing her hands in the process.

Kirumi then stops as she encounters a large group of buzz saws hanging throughout the walls. The saws then activate, but she proceeds to climb through. As she makes her way to the top, her skin gets slashed and lacerated several times, causing her to scream in pain. Soon after she escapes from the saws, she gets worn out and a lot of her clothes are cut off. She then looks up to see a blue sky and sunlight pouring through a hole on the ceiling. Thinking that it is a way out, she continues climbing and reaches for the gap. Instead, she touches the ceiling and the hole turns out to be a children's drawing of a sky and a sun. The vine then breaks, causing Kirumi to fall. On the ground, Monodam shoves Monosuke below where Kirumi is falling. She then falls onto Monosuke, which killed her and destroyed Monosuke in the process.

Trivia

 * The execution's intro shows Kirumi running away from Monokuma, rather than her being dragged away by him.
 * Monosuke is destroyed in this execution.
 * The vine tied to "nothing" Kirumi is forced to climb seems based on a magic trick called the Indian Rope Trick.
