Istina is cool-headed and rational, though somewhat introverted. She often absorbs herself in her hobbies: the meticulous study of more profound Originium Arts, the study of the latest social theories, observation of others and their relationships, and fashion.

Over the course of her multiple interactions with the Ursus Student Group, Istina displayed rare communication abilities and an assured manner, and gave clear and focused answers. We are certain that Istina intends to hold proactive exchanges with Rhodes Island, and may be a positive factor in communication with the Ursus Student Self-government Group.

Archive File 2

It is now known that the 'Ursus Student Self-government Group' was originally proposed by Istina. The group's establishment helped the Ursus students work together and get past the initial phase of isolation and mutual distrust.

During consultation, Istina keenly answered several questions concerning Zima. Istina believes that although Zima is rude and sometimes unreasonable, she attaches great importance to her companions in the Self-Governing Group and is a competent leader. And if she could add her own input during operations, this would be even better.

While discussing Zima, the Doctor made many pointed remarks, but Istina gave opposing opinions. Istina believes that Zima will not become a destabilizing force for Rhodes Island, and that to believe that her ambitions extend only as far as Rhodes Island would be to underestimate her.

Archive File 3

Istina was born in Chernobog, a city in the Empire of Ursus. Her parents were both employed in local agencies. During the periodic riots by student organizations, Istina declined to participate and instead chose to read quietly. As she had no interest in the loud music and partying of her peers, she began to read some particularly interesting books coming out of Londinium, Victoria at the time. From these, she started to reevalute everything she thought she knew, and began to see everything in a new light.

Archive File 4

With regard to her whereabouts during the Chernobog incident, Istina modestly and succinctly declined to answer, but she showed several changes of emotion in doing so. On account of Rhodes Island's current policies and the need to protect certain company secrets, investigations into the Ursus Student Self-government Group have temporarily ceased.

In view of the background investigation into the Ursus Student Groups, there is no need to question Istina's background. Because of this, it is advisable to use psychologically founded methods to communicate with Ursus students. Future options for cooperation should be provided based on the suitability and independence of the student union members.

Note: Based on Istina's intense level of interest in the books in the Doctor's office, it is advisable to give her a degree of reading privileges.

    Module record

    Pastry flour 180g; cystymilk 120g; icing sugar 90g; dried berries 60g; fowl yolk 22g; salt 1g

    They might be the most basic cookies, but Gummy loves these.

    Let cystymilk sit at room temperature, then add the icing sugar. Once evenly folded in, add the fowl yolk. Dice the dried berries finely (full chunks will be slightly sour). Sift in pastry flour, knead until smooth, then trim and cut into 4 x 4cm squares.

    NB: If these are for Sonya, make bigger. Natalya likes more salt in hers. Drizzle honey for Rosalind's.

    Place in freezer to rest for 1hr, then transfer straight into a preheated 170°C oven for 20min until done.

    ......

    I see... And I thought all along the chief would turn out to be the true mastermind! Now that I look back at previous descriptions, he did plenty that he wouldn't have done otherwise. Blatantly letting the protagonist go on with the investigation, making such a solemn vow at the meeting, and him and his wife truly being in love all along, not a political marriage... He even began by committing suicide...

    The author's deliberately crafted narrative tricks may have had their impact, but I did still let first impressions blind me to many unusual details.

    It may be that people truly can be affected by information from all sides given specific circumstances, and end up overlooking facts that should have been obvious.

    I've overlooked a lot, that much is true.

    This is something I'll have to reflect on frequently in future.

    ......

    I've borrowed several books from the Doctor throughout my time here at Rhodes Island. As a student, I've certainly been through things most others my age have not yet. It's beyond me to more deeply comprehend some conundrums posed in books with my current level of knowledge, but with my experiences, perhaps the author's intent is something I can feel out.

    Pertinently, the passage on the 'mass' in Chashcha Lesa: 'Those who have done wrong once find they are not punished, for those around them who know of it will opt to turn one's blind eye to carry on living one's 'days of well-being,' so accordingly the wrongdoers will then go to do wrong a second and third time. May there merely be one willing to fix their firm eye and raise their voice, and this chaos can be dispelled.'

    May there merely be one willing to fix their firm eye and raise their voice, and this chaos can be dispelled., Excerpts from Istina's reading notes

Appointed as Assistant
Greetings, I'm here for my shift… That's a peculiar look on your face. Do I seem so unreliable?
Talk 1
We don't throw ourselves into battle because we want to. We just have a stronger will to survive than most. If you understand, that alone would be enough.
Talk 2
Zima, the girls, and I all came from different schools. But all the students in the city knew the legends of General Zima. Doesn't that sound cool? Literally. Zima is Ursine for 'winter', you see. Hm, yes.
Talk 3
How did we escape from Chernobog? Hmm... you really don't want to know. Sometimes the truth is better left untold.
Talk after Promotion 1
Oh? I'm reading a mystery novel… As a matter of fact, it taught me some lessons that proved useful in getting me through that terrible time.
Talk after Promotion 2
My favorite books? Hmm, I enjoy topics like politics, economics, and dialectical materialism… Baking magazines and stuff like that are nice too.
Talk after Trust Increase 1
Home? My hometown? Obviously, we can't go back there. You know as well as I do that there's nothing left of it. Even if we rebuilt Chernobog, I still…
Talk after Trust Increase 2
Rhodes Island is safe. And there are so many books here in your office... If I could, I'd really prefer to stay here…
Talk after Trust Increase 3
What will I do in the future? Hmm… No idea. My books don't have an answer for that. I hope someone will offer me one, someday…
Idle
Such a twist is beyond my imagination. 'Every last one of the passengers on this train, you're all murderers!'
Onboard
I am Istina. I'm still a student, but I was recruited for my ability to use Arts… Yes, it is rather strange for a student to serve here, isn't it?
Watching Battle Record
You want me to be stronger?
Promotion 1
Do you feel like you understand me better now? Naive, you're far from really knowing me.
Promotion 2
Now that you've offered me such recognition, I will reveal my true power. Allow me to demonstrate by reducing this office to a fine powder… Just kidding. There are too many precious books here. I would never do something so awful.
Added to Squad
Understood.
Appointed as Squad Leader
Hmm… The team is somewhat different from what I imagined.
Depart
Let's show our determination, earnestness, and boundless passion.
Begin Operation
May the star of victory shine upon us.
Selecting Operator 1
What is it, Doctor?
Selecting Operator 2
Go ahead.
Deployment 1
I have a distaste for war.
Deployment 2
It seems we must fight.
In Battle 1
Come at me.
In Battle 2
Please, no need to rush.
In Battle 3
Let us take it slow.
In Battle 4
Time to teach you a lesson.
4-star Result
Why do they fight... even when it may cost them their lives? What do they gain from it?
3-star Result
Doctor, if you have to commend us, now is the time.
Sub 3-star Result
Those enemies who fled... We probably won't see them again.
Operation Failure
Neither our numbers nor our efforts were sufficient…
Assigned to Facility
A secret room, where, shall we say, interesting things happen.
Tap
What?!
Trust Tap
It's too noisy here, I'd rather read in the Doctor's office.
Title
Arknights.
New Year's blessing
No, I, I'm not honey-drunk, Sonya just poured me a, a little, but I just felt I should convey to you, a, Happy New Year... Er, are these Sonya's flowers? For the New Year? Why is this flower, burning hot to the touch…
Greeting
Hello, Doctor.
Birthday
Happy birthday, Doctor. This hardcover is my gift to you, Ah, well done, you've discerned without so much as a flip that it contains not literature, but cake. No, I wasn't at all hoping to see you scoop up a handful of icing…
Anniversary Celebration
'The Silver Branch', 'Mathematical Theory of Originium Arts', 'Superpropositional Logic'... Hm? I'm going through the books I've read this year. Suspense fiction has its merits, but dipping into all manner of knowledge is comforting, in a sense. It lets me believe, undeniably, that I am moving forward.
