Infection Status
[Cell-Originium Assimilation]
15%
The Operator bears clearly visible Originium crystal formations across multiple locations on her body.
Despite the severity of her infection, progression has remained unusually stable.
This stability is believed to be related to the Operator's unique physiological characteristics.
Further investigation is prohibited without authorization from Kal'tsit.
[Blood Originium-Crystal Density]
0.40u/L
As a Sarkaz, the Operator's long-term prognosis remains unfavorable.
However, conventional models fail to accurately predict the progression of her condition.
Regular examinations are mandatory.
The Operator frequently ignores them.
[Somatic Cell and Originium Fusion Rate]
14%
Fusion remains stable.
No abnormal progression has been detected under ordinary observation.
This does not explain the Operator's ability to survive injuries that should result in immediate death.
[Additional Blood Originium Data]
Insufficient authorization. Data restricted.
Comprehensive Physical Examination
[Physical Strength]
Excellent
Able to carry wounded personnel over considerable distances while already suffering severe injuries herself.
Demonstrates little regard for physical exhaustion.
[Battlefield Mobility]
Excellent
Mobility increases dramatically when wounded personnel are detected nearby.
Medical staff have repeatedly observed the Operator moving toward casualties despite being ordered to withdraw.
[Physiological Endurance]
Outstanding
Pain response is abnormally suppressed.
The Operator routinely exceeds safe physiological limits.
She has demonstrated the ability to remain operational after injuries that would incapacitate experienced combatants.
[Tactical Planning]
Good
Displays strong situational awareness and exceptional judgment during medical triage.
Particularly effective when simultaneously managing multiple casualties.
[Combat Skills]
Deficient
No formal combat training has been identified.
The Operator possesses adequate defensive instincts but demonstrates a strong reluctance to deliberately injure others.
When given the choice between eliminating an enemy and rescuing an ally, she will almost invariably choose the latter.
[Originium Arts Adaptability]
Good
Arts manifest primarily through:
Thermal regulation
Biological stabilization
Accelerated tissue recovery
Wound transfer
Originium absorption
The Operator's Arts display characteristics inconsistent with ordinary Sarkaz Arts.
Her ability to regulate internal thermal output strongly corresponds with known Diαblo characteristics.
[Objective Résumé]
Former frontline combat medic.
Records preceding her appearance in Kazdel are fragmented, contradictory, or deliberately erased.
The Operator possesses exceptional emergency surgical knowledge and is capable of performing complex procedures under battlefield conditions with inadequate equipment, little or no anesthesia, and active enemy fire.
She refuses to abandon wounded individuals regardless of personal risk.
Her medical philosophy can be summarized as follows:
"If they are still breathing, then treatment has not failed yet."
[Contract Description]
A medic who does not fight.
A medic who does not retreat.
A medic who will continue working even after being declared dead.
Sacrifice entered into a long-term medical support agreement under one condition:
She will never be ordered to prioritize an objective over the lives of patients under her care.
Command staff are advised not to issue such an order.
They will be ignored.
[Clinical Diagnostic Analysis]
Operator Sacrifice exhibits signs of severe emotional blunting consistent with prolonged exposure to extreme trauma.
However, this should not be interpreted as an absence of emotion.
The Operator experiences attachment, concern, grief, and affection.
She simply expresses them through action rather than language.
Her oath functions as both a psychological anchor and a behavioral compulsion.
She does not appear to consider her own survival an essential component of the equation.
When confronted with the possibility of her own death, she does not display fear.
She displays calculation.
If her death allows her to save another person, she considers the exchange acceptable.
This mentality has become increasingly dangerous.
[Archive Record One]
Sacrifice was first encountered operating alone within a ruined Sarkaz settlement.
She was performing emergency surgery in open terrain while artillery strikes continued around her position.
She had no anesthesia.
She had almost no usable surgical equipment.
When asked why she had not withdrawn, she replied:
"The patient was still breathing. That was sufficient justification."
[Archive Record Two]
The Operator demonstrates unusually strong resistance to Originium-induced fever.
Her internal thermal output appears to regulate itself automatically, preventing accidental thermal injury to patients during treatment.
This trait was initially considered a medical anomaly.
Following confirmation of her Diαblo lineage, this assumption was revised.
The exact mechanism remains unknown.
[Archive Record Three]
Despite displaying minimal emotional expression, Sacrifice consistently visits recovered patients long after treatment has concluded.
She rarely speaks during these visits.
She checks their pulse.
She checks their breathing.
She examines old injuries.
Then she leaves.
When questioned about this behavior, she stated:
"I need to know they remained alive."
[Archive Record Four]
[Authorization Level 8 Required]
The circumstances surrounding Operator Sacrifice's repeated resurrections remain classified.
Available evidence suggests the phenomenon involves an interaction between her Originium Arts, physiological structure, and an unidentified external factor.
The Operator has repeatedly sustained injuries incompatible with survival.
She has subsequently resumed activity.
In several cases, the interval between clinical death and renewed movement was less than several minutes.
In others, the interval was significantly longer.
The Operator herself provides no useful explanation.
When asked what happens after death, she answered:
"I don't know."
When asked why she continues returning:
"There are still patients."
[Witness Statement]
"The Operator was witnessed taking fatal damage and being declared dead multiple times, only to stand up again and return to the wounded.
One time, I watched an arrow pass directly through her heart.
She collapsed.
I thought she was dead.
Then she stood back up, pulled the arrow out, and walked away to look for the wounded.
She didn't even stop to treat herself."
[Abertha]
The name Abertha was given to Sacrifice by Theresa.
The Operator initially appeared confused by the request to give her another name.
When asked whether she disliked the codename "Sacrifice," she answered:
"It is accurate."
Theresa reportedly disagreed.
She chose the name Abertha because she believed the Operator represented a light brought to people who believed they had already been abandoned.
The Operator accepted the name.
She continues to answer to Sacrifice during operations.
She answers to Abertha when Theresa calls her.
This distinction appears significant.
[Promotion Record]
Following promotion, Operator Sacrifice demonstrated improved control over her internal thermal output.
Her Arts became sufficiently precise to permit complex surgery while simultaneously manipulating biological temperature and Originium activity.
She refused all commendation.
"Saving lives is not exceptional."
"It is expected."
[Special Annotation]
Operator Sacrifice will disobey direct orders if those orders conflict with her medical oath.
This behavior has already been confirmed.
Attempts to correct the behavior through disciplinary measures are strongly discouraged.
They have no effect.
The Operator does not interpret such disobedience as rebellion.
She interprets it as fulfilling her contract.
[Operator Class & Archetype]
Class: Medic
Branch: Therapist Medic
Position: Ranged
Attack Type: Healing
Block: 1
Trait
Restores HP to allied units.
Prioritizes allies with the lowest HP percentage.
Can reduce the effects of Elemental Damage and abnormal statuses through sustained treatment.
[Talents]
Talent 1 — Oathbound Triage
Unlocked at Elite 1 · Enhanced at Elite 2
When healing an ally below 40% HP, Sacrifice's healing effectiveness increases.

Unlocked at Elite 2
Sacrifice takes reduced Arts and environmental damage.
When her HP falls below 50%, her healing range temporarily increases.
The effect has a cooldown.
Clinical Note
The Operator's internal Originium activity behaves similarly to a stabilized thermal core.
The comparison is purely theoretical.
For the safety of everyone involved, do not attempt to test whether it actually is one.

[Kal'tsit's Evaluation Notes]
Evaluator: Kal'tsit
Authorization Level: Restricted
Operator Sacrifice presents a paradox that I have encountered before, but never become accustomed to.
From a medical standpoint, her value is unquestionable.
Her triage efficiency under extreme conditions exceeds established benchmarks, including those of veteran battlefield physicians.
Her ability to stabilize patients who should, according to conventional medical models, already be dead warrants continued investigation.
Unfortunately, the same capability creates an unacceptable operational risk.
She does not perceive her own survival as a variable worth accounting for.
This is not bravery.
It is not conventional martyrdom.
It is a structural failure in her decision-making process.
Her oath provides psychological stability while simultaneously preventing her from disengaging when disengagement would be medically or strategically preferable.
Her condition is made more dangerous by her resurrection phenomenon.
Death has ceased to function as a deterrent.
It is merely an inconvenience.
Do not mistake this for immortality.
She can still suffer.
She can still deteriorate.
Her infection can still progress.
And eventually, there may be nothing left for her resurrection to restore.
She knows this.
She continues anyway.
Her Diαblo characteristics are genuine, but they do not adequately explain the phenomenon.
There are other factors involved.
I will not elaborate further in this record.
She is not a weapon.
She is not a miracle.
She is a promise that refuses to break.
And promises can break.

[Amiya's Evaluation Notes]
Evaluator: Amiya
Access Level: General Command
When I first met Sacrifice, I thought she disliked me.
She rarely speaks unless necessary.
She doesn't smile very often.
When thanked, she simply nods and asks for the patient's vital signs.
At first, I thought she was distant.
Now I understand.
It isn't distance.
It's focus.
Sacrifice carries the weight of every life she couldn't save, and she carries it quietly.
She never talks about her past.
Sometimes, however, I see her sitting beside the infirmary beds long after her shift has ended.
Checking pulses.
Checking breathing.
Checking people who are already asleep.
She doesn't believe she deserves rest.
That worries me.
But when casualties rise, when Operators are injured beyond what should be survivable, she is there.
Calm.
Precise.
Unyielding.
I've seen people survive because she simply refused to let them die.
She once told me:
"Leaders choose objectives. Doctors choose people."
I think Babel needs people like her.
But we also need to protect her.
From the battlefield.
From her infection.
And most importantly—
from herself.
Theresa gave her another name.
Abertha.
I think Theresa understood something the rest of us didn't.
Sacrifice isn't only what she gives.
It's what she believes she must give.
And perhaps Abertha is the name of the person who might one day learn that she is allowed to receive something too.

[Appendix A — Resurrection Phenomenon]
Restricted
Operator Sacrifice has demonstrated repeated post-mortem activity inconsistent with established Originium medical models.
Confirmed cases:
3
Unconfirmed eyewitness accounts:
7+
Confirmed cases involved:
Complete cardiac penetration
Lethal blood loss
Neural shutdown exceeding conventional recovery thresholds.
Massive tissue destruction
Extensive skeletal trauma
In every confirmed case, the Operator resumed activity without conventional resuscitation.
In no confirmed case did the Operator attempt to stabilize herself before assisting other wounded personnel.
The phenomenon appears to be partially connected to her oath-driven behavior.
Whether the oath causes the phenomenon or merely influences it remains unknown.

[Appendix D — Infection Progression Notice]
Following Incident RI-KZ-17:
Cell-Originium Assimilation:
11% → 14.8%
Blood Originium Crystal Density:
Increased to 0.40u/L
Thermal Output Stability:
Temporarily degraded
The Operator displayed no significant reaction to this information.
When informed of the potential long-term consequences, she asked only:
"Are the patients alive?"
[Appendix E — Battlefield Endurance Incident]
Classification: Restricted
During an extended campaign, Operator Sacrifice remained continuously active for approximately fifteen days.
No conventional sleep period was recorded.
During this period, the Operator sustained numerous lethal injuries.
At least twenty deaths were reported or witnessed.
In several cases, she deliberately inflicted fatal injuries upon herself after determining that recovery through ordinary means would require too much time.
Each time, she returned to active medical duty.
When questioned about the practice, she answered:
"It is faster."
Medical personnel have been instructed to consider this behavior a severe medical emergency.
The Operator has ignored this instruction.
[Appendix F — Final Medical Assessment]
[Restricted — Kal'tsit Only]
The Operator's condition cannot be classified as conventional immortality.
She can die.
She does die.
Repeatedly.
Something simply refuses to allow death to become the end of her duty.
Whether this is an expression of her Diαblo lineage, an abnormality caused by Originium, an external phenomenon, or something else entirely remains unknown.
Further investigation is required.
However, there is one conclusion that requires no investigation:
The Operator cannot be permitted to continue treating her own life as expendable.
Unfortunately, no known order can force her to believe otherwise.
[Final Classification Note — Kal'tsit]
Operator Sacrifice does not disobey orders out of rebellion.
She does not seek death.
She simply no longer considers death a sufficient reason to stop.
That distinction is important.
Because one day, she may discover a death from which even she cannot return.
Until then—
keep her alive.
And if she refuses to stay alive herself,
make sure someone is there to drag her back.
