Picture Scroll of Punishments Past and Present (今昔仕置絵巻 konjaku shioki emaki) is an execution in Danganronpa V3: Killing Harmony, with Korekiyo Shinguji being executed, and Monodam being destroyed in the process.

Sequence
Korekiyo is tied from the ceiling. Monotaro and Monofunny then begin to rapidly spin Korekiyo around before having his ties from the ceiling cut off by a samurai and falling down a hole.

He lands into a boiler. Monotaro and Monofunny ignite the fire and start boiling Korekiyo. He promptly starts crying blood. Monodam jumps into the fire under the boiler, killing himself along with Korekiyo.

Korekiyo's soul is freed, and he reunites with his sister Miyadera. They share a happy reunion until Monokuma shows up as a shinto priest and sprinkles salt onto Korekiyo. Miyadera joins in the sprinkling as Korekiyo is "purified" and dissolves into another plane of existence. Monokuma and Miyadera then sit on a perch overlooking the city as the execution ends.

Trivia

 * The ending of the execution can be interpreted in different ways. Korekiyo's soul could have ceased to exist after having the salt thrown at him, or the salt could have caused his soul to fade away into the afterlife, a purgatory, or another life plane.
 * Monodam is destroyed in this execution.
 * The execution features an array of punishment, torture and execution methods used in Japan historically, along with customs from antiquity.
 * The execution begins with Korekiyo being tied in what is known as a "shrimp tie" (海老責め ebizeme, more specifically "reverse shrimp tie", a kind of bondage (see Hojōjutsu) used in the Edo Period as a torture and interrogation technique, as the position it forces on the victim causes a burning sensation over time. Interestingly, a variation of this archaic bondage is used today in BDSM (short for Bondage Dominance Sato-Masochism, see Shibari), making this punishment reflective in a way of Korekiyo's unorthodox relationship with his sister.
 * The way the rope binding Korekiyo is eventually cut by a man holding a katana seems to be reflective of Seppuku, specifically the stage where after the disembowelment itself an attendant beheads the subject of the ritual.
 * The actual method of execution used on Korekiyo, that is death by boiling, was a form of state approved execution method for severe criminals in the Tokugawa Shogunate. One notable character in Japanese history and theatrical tradition who suffered this fate is Ishikawa Goemon
 * Throwing handfuls of salt as a means for expelling evil spirits is a tradition in Japan originating in ancient history. Also, the outfit Monokuma wears for this stage of the execution is often identified with Onmyōji, practitioners of Japanese esoteric cosmology, who are traditionally said to have been capable of communicating with and controlling spirits.
 * The scenery Monokuma and the spirit of Miyadera are viewing in the closing of the execution seems to based on ancient Kyoto, which served as the capital of imperial Japan from antiquity until 1869.
