under the same sky

First, a bit of backstory.

1) Early on in the DRK books, Yui Samidare asks Kyoko to call her "big sister." We learn that Yui lost her actual little sister when she was abducted for ransom and ultimately killed. The case went cold and the perpetrator was never found - leading to Samidare becoming a detective. By the second and third books, it's clear from Samidare's internal thoughts that she'd take nearly any opportunity to find her sister's killer. 

2) Most of the series involves our lead duo getting dragged into various "Duel Noirs" that are set up by the so-called "Victims' Catharsis Committee." These are scenarios in which so-called "Victims" are challenged to kill their "Targets" (someone who did something to them or someone they love). Each Duel also has a "Detective" and an "Innocent" who are sent a letter informing them of a location where they must go. And the Victim can opt to invite more than one “Innocent,” too! What happens at the location where the Detective and Innocent(s) are led is really up to the "Victim" - but it often involves the Victim, with the Committee’s help and support, setting up some elaborate game or puzzle designed to perhaps kill the Target, perhaps ensnare/delay the Detective, perhaps frame an Innocent as the mastermind, or perhaps some mixture of the above. Note: The Victim is not allowed to kill the Detective. Victory for the Victim means they are given the chance to set up with a new identity in a new country and given a monetary reward. Failure for the Victim means the Committee cuts all ties and leaves them to face justice.

Based on the above points, you probably already know where this is going. I’ll warn you that we don’t actually have a full translation of the final book or anything like that. So what we know about how it turns out is partly courtesy of Reddit, partly courtesy of the Wiki, and partly courtesy of both @siknakaliux‘s summary of the conclusion and @yuissamidare ‘s own distinct summary plus an ask that @drmedicsgamesurgery answered for me just recently. So credit to all of them, but also: Because I’m gluing all these pieces together, it’s possible we’ll one day learn more context that will provide some changes to this summation.

Let’s get into it.

(Spoilers for Danganronpa Kirigiri Vol. 7 under the cut. There will be many details as well as some complaining.)
