CR-S01

Is named Erhard Muller, a fact that already made the rounds in the 2010s

His nationality is also listed as German, though he clearly spent most of his life in America

Most of his backstory isn't anything new compared to in the games, but the artbook does provide a timeline: adopted by Professor Sartre at age 9 after his parents died, enrolled in medical school at age 12 and hailed as the youngest ever to do so, age 13 when Rosalia was adopted, age 16 when the Cumberland Institute incident happened

Erhard and Rose weren't super close siblings, but got along well enough and they had happy lives until the bioterrorism attacked

The government 100% knew Erhard wasn't the culprit when they arrested him - he was the public scapegoat because they couldn't find Albert Sartre, their real person of interest. They never stopped looking for Sartre, and S01's work to reduce his sentence was a quiet compromise for the fact that they, y'know, ruined this kid's life

After learning the truth, S01 is disappointed at his father's betrayal but also chooses to take blame for Sartre's crimes and work off his sentence rather than expose Sartre as the true culprit

Not in-game lore, but according to the concept art section he was nicknamed Chris (CRS) during development. Other people will be funnier about this than I am

Maria Torres

Has the shortest bio and the least amount of new information along with Tomoe, honestly

Born in the slums

Was already at the orphanage at age 10 when Rosalia (age 3) came there

Ended up in rehab of some kind after the orphanage fire

Hank Freebird

Also doesn't have much new compared to the game, sadly

Joined the military out of a sense of justice, left out of disillusionment following John's death and used the medical knowledge he gained in the military to become an orthopedic surgeon (not that this wasn't already implied in the game)

His bio specifically calls him out for being kinda clumsy/goofy. Poor guy

Tomoe Tachibana

Honestly the only thing that's new is a bunch of names, so this is the one time I break my rule and cite a translation directly. TAKE THIS WITH A GRAIN OF SALT, IT'S STILL A MACHINE TRANSLATION

The only daughter of the Tachibana Zaibatsu, a global organization run by a family descended from the leader of the Koga Shinobi Army, Hisayori Tachibana.

Gabriel Cunningham

Nationality is listed as Great Britain. Surprise!

His wife Lisa left him with Joshua and went to her parents' six years before the game because she didn't like his lifestyle

Lisa was willing to get back together if Gabe was ever willing to talk to her properly, but as seen in the game he kept his distance. He and Lisa met occasionally over the next six years, but he never saw Joshua - which is of course why Joshua never recognized him in the game

His decision to go through with the divorce was about acceptance of his failings and a desire to do right by Joshua and Lisa

Naomi Kimishima

NOW WE'RE COOKING WITH BACKSTORY

All right, so that bit in Second Opinion where she took a Savato sample after cutting ties with Delphi and used it to bargain amnesty with Caduceus [Europe in the US version; US in the JP version]? Yeah, apparently she transported that sample by CARRYING IT IN HER OWN BODY for Caduceus to extract

Her fatal condition is a result of that, though it's already implied to be a result of GUILT in the game anyway. It was a sudden development a few years later, followed by Derek's six-month diagnosis

There's also details about her illness! Apparently her specific brand of PGS or whatever involves excess serotonin and dopamine production, which she needs meds to regulate.

It also means she's no longer able to operate on the living, which is why she transitions to forensic medicine as part of her plea deal

[Insert grimace here] I don't want to get too into this because this bit because 1) machine translation fears, 2) even perfectly translated it's not likely to be accurate to actual philosophy/terminology anyway, 3) I'm not a doctor I don't know what I'm talking about…

But the bio then starts talking about pranayama and prana, defining prana as life essence and...saying Naomi lacks it because of her condition and its effect on serotonin? I'm not entirely clear on this and I'm hesitant to say anything for sure; the main thing is that they take her illness and use the concept of prana to connect that to...

Her new ability to hear the dead! Apparently Naomi reads the prana left behind in a corpse and translates it into the person's final words via her phone; the worse the damage to the corpse (e.g., skeletonization), the less prana remains and the weaker the voice she hears is

Whether any of this relates to the Healing Touch is not mentioned. IDK man

Technically this was in S01's bio, but it relates more to Naomi: Jacob Tillman originally wanted Naomi to perform his surgery and keep it secret. Naomi was already unable to perform surgery on living people at that point, though, so S01 was Plan B

Rosalia Rossellini

Admired her big brother Erhard :(

Albert Sartre

Adopted Rosalia to study the virus in her blood (that is, he already knew about it by the time he adopted her in case that's ever a timeline question)
