Katashiro Island Case

**Katashiro Island Case** is a minor case and the second of three Shoot Down The Angel Challenge Duel Noir cases featured in the sixth volume of *Danganronpa Kirigiri*.

## History

The Katashiro Island case seemed to be heavily inspired by Agatha Christie's 'And Then There Were None' novel, which had ten people lured to an island where they would be picked off by a killer. The name, Katashiro, was a reference to Yorishiro, an object used to attract spirits in Shinto religion, and involves self-purification. It is made by cutting washi paper into human figures. Katashiro Island is an uninhabited, dome saped, shrub filled island located in the Sanriku shoreline of Touhoku. Officially, it's known as Hirashima island, but its commonly known more as Katashiro Island.

Kyoko Kirigiri and Yui Samidare, taking residence at the harbor town that was the closest to Katashiro Island, and deduce that the Victim for this case was going to prepare in advance to kill nine victims using one Technique each, while leaving the tenth person, the Detective, alive. They also come to the conclusion that the two Triple Zero detectives, Licorne and Johnny Arp, had already used their wealth, be it a jet from a US military base or otherwise, to reach the island and would be perching on the highest point of the mansion there.

Kyoko and Yui's strategy for this portion was to try to snipe Johnny himself, or rather his gun. Once Johnny was putting the final bullet inside his gun, Kyoko would snipe it in order to destroy it, effectively ruining the defenders chances of stopping the attackers. In order to do this, they initially planned to use two boats, with both splitting off on one each. Yui would be on the boat to arrive at Katashiro Island first and is with a decoy Kyoko, which is just a cloth on top of something and secretly held together with rope to give the illusion it's Kyoko. This is meant to get Johnny to waste his first bullet. This gives Kyoko's boat time to come to shore, and she would be covered with cloth, so Johnny would waste his second shot on her to confirm it. During that less of a second window of opportunity, she would try to snipe at Johnny's gun to destroy it.

The Duel Noir started at Midnight, but Yui and Kyoko made their move 5 hours later. Unfortunately, before their plan could even be enacted, Kyoko's ribbon is sniped almost immediately by Johnny all the way from Katashiro Island and the ocean to their shore. They had misjudged his sniping capabilities and never expected he could a hit a target that not only 3,000 meters away, but also moving as well. Thus, Kyoko and Yui lost the second round. Still, despite this, they still go to Katashiro Island an hour later only to see nine identical victims with their faces cut off. At this point Ayako Saiko, the assigned Detective of this case, arrives and directs the girls away since she wants to solve the Duel Noir by herself in order to get the credit from it. Deciding to leave it in her hands, the girls depart in order to await the final round.

Later on, they would hear a news report detailing Ayako solving the crime, the entire island being able to slide horizontally at 2 meters above sea level, and that a 'Birlstone Gambit' was used with the bodies. It's unknown if the Victim was taken in by the actual authorities or if the Victim was handed over to the Victims Catharsis Committee to be possibly executed.
