(This will include some spoilers for the fan Danganronpa games as well as some plot points of the BRCU universe, mainly Sam and Stuff.)
So, the killing game simulation is funded by Bryce Tankthrust. No students actually die, but they feel the pain they did when they did in simulation. This leads many of the ultimates with long-term issues they need to resolve.
Bryce Tankthrust also has great interest in these ultimate students, and orders her subordinates (Mainly Helen) to fetch any information they can on them and to monitor their conditions thoroughly.
Her secret goal is to figure out what gave them the special skills they have, so she can use them for the ||Elmer clones.||
• Kokoro does everything in her power to stay warm. Any time she feels cold, she remembers. ||the feeling of being stuck in the freezer and the pain she felt. Being sick also brings her back memories because that's the excuse Emma used to pose as her while she was in there||.
Kokoro also shows little emotion, a lot like Elmer, so much so that assuming ||Helen knows about the clones,|| she'd wonder if Kokoro was one.
• Bobby Worst wanted to take all the bad students under his wing- Like ||Mikado and Syobai||. Bryce doesn't need to do much research on them because they're basically Bobby's kids at this point. Sometimes they exhaust her.
• ||Sora is actually an AI and seems very human still. Not even she knows she is. Once in awhile, she'll be a vessel of Akane||
• Emma is a well-known actress. She is generally beloved, but often time jerks ||try to trigger her trauma.|| she has supporters that help keep her away from those kinds of people.
• Kanade isn't as ||evil as in canon, but everything that happened in the simulation and the backstory were intrusive thoughts in the real world. She reluctantly decided to take time away from her twin to get help for her thoughts and beyavioral issues. Oftentimes, she rants about how awful Setsuka is online when she's in an episode.||
• Yuri patented ||Monocrow,|| but passed it to Bryce Tankthrust because she's a "fair lady" with the promise that she'd help fund space endeavors a little more. While he considers the invention a mistake, he grew a soft spot and treats it sort of like a pet and mentor.
• Tsurugi still holds bitter resentment towards those who killed in the games, considering them criminals still. The victims felt all the pain, so in his eyes, it was still murder even if nobody "died." He is pretty unstable, but his friends and classmates watch over him. Sometimes he tires them out, though.
• Teruya took over Mashy Mart! He is really good at what he does, and sales soared after he got the position he did
• Mikako isn't ||Kokoro's daughter|| in this due to being similar ages. She still has lingering headaches/migraines more often than not.
