Ultimate Annihilation

Ultimate Annihilation (才囚学園の破壊 lit. The Destruction of Gifted Inmates Academy) is an execution featured in Danganronpa V3: Killing Harmony, with Tsumugi Shirogane, Monokuma, and the entire academy being executed by K1-B0.

In the end K1-B0 committed suicide by destroying himself along with the entire Ultimate Academy for Gifted Juveniles.

Shuichi Saihara, Himiko Yumeno, and Maki Harukawa, who were supposed to be executed as well in this execution, managed to survive and end the Killing Game.

Prelude
Due to the unexpected outcome of the last trial, where no one casts their votes; Tsumugi and Monokuma were forced to end Danganronpa and K1-B0 was ordered to shut everything down. Since this was an unexpected execution, Tsumugi hadn't prepared a proper one and she trusted the work to K1-B0; to execute herself and Monokuma, which the Ultimate Robot did not hesitate to do since he wanted the killing game to stop and help the remaining survivors.

Sequence
Launching from the class trial room, K1-B0 immediately shoots the entire academy at random with his upgraded laser, his free will finally allowing him to bring down the academy and end the killing game for good.

In the next scene, Tsumugi is seen in front of the door of the academy in cosplay as Junko Enoshima, imitating Junko's hand waving and grin in The Ultimate Punishment. However, as Monokuma drops down, she takes off her cosplay revealing her true expression, saddened and disappointed, still waving her hands along with Monokuma, as both of them are swiftly crushed by a falling rock.

Following the demise of the mastermind and Monokuma, K1-B0 intentionally let Shuichi, Himiko, and Maki survive. After confirming that the three of them were still alive, K1-B0 smiles before self-destructing himself and flying directly into the wall that surrounded the academy, shattering the glass cage and creating an opening to the outside world, with a final tune of the execution music playing, thus ending Danganronpa for good.

Aftermath
When the audience from the outside world decided to abandon Danganronpa, this reality show series created by Team Danganronpa will be no more and marked the 53rd Killing Game as the last season of the story. This execution led into Danganronpa V3's epilogue, where the survivors ponder the actual nature of the killing game, the mastermind, and the outside world, before proceeding into it together.

Trivia

 * Like most other executions, this one begins with a pixel art-style animation. However, unlike most, which feature the trial's blackened being dragged off-screen by Monokuma, this one instead features Tsumugi, Shuichi, Himiko, Maki, and Monokuma stood in front of a hovering K1-B0, before he puts on his mask and flies off. It has the text "Tsumugi, Shuichi, Himiko, and Maki will receive punishment. Time to destroy the Ultimate Academy."
 * The only other executions with a unique animation are The Ultimate Punishment, Please Insert Coin, and Strand of Agony
 * The intro also features the most characters of any execution, with the only other one that features more than two characters being Please Insert Coin.
 * This execution was of the most characters at once of any in the series.
