Kirigiriso

 is a PC sound novel bundled with the third blu-ray box set of Danganronpa 3: The End of Hope's Peak Academy. The story follows the actions of the Ultimate Detective, Kyoko Kirigiri.

Summary
The main character is a normal student with nothing unusual about them. While taking a shortcut home, they get lost, and end up driving through a thick forest. Driving on the road that’s difficult to see, the main character meets a mysterious, beautiful girl named Kyoko Kirigiri, and offers to give her a ride in their car.

However, their drive together does not last long. The main character gets into an accident, and the two seek refuge in a nearby Western-style house. This house was actually where Kirigiri was headed, but it has a strange atmosphere and a huge tree growing inside.

The characters are assaulted by a creepy suit of armor, a skull buried in the flower bed, and a girl who’s the spitting image of Kyoko.
