Strand of Agony

Thread of Agony (苦悶の糸 Kumon no ito, lit. An agony thread) is an execution in Danganronpa V3: Killing Harmony, with Kirumi Tojo being executed and Monosuke being destroyed.

Sequence
Kirumi is being chased through a hallway by a group of protesters. As she tries to run away, she gets blocked off by another group. 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, because of 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, she 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. As Monosuke frantically looks for his glasses, Kirumi falls onto Monosuke, killing her and destroying Monosuke.

Monodam then looks over Kirumi's corpse and Monosuke's now destroyed body as various red roses flutter and fall to the ground. The children's drawing, which was previously attached to the ceiling, descends and lands onto Kirumi, soaking it with her blood.

Trivia

 * Because Kirumi previously tried to escape from the class trial room before the execution, the intro shows Kirumi running away from Monokuma rather than her being dragged away.
 * The vine tied to "nothing" Kirumi is forced to climb might be based on a magic trick called the Indian Rope Trick.
