Operator Overview
Name in Cyrillic: Истина
Meaning of name in Russian: Objective Truth
“You want to praise us? Do it now, then!”
For the sake of maintaining her reading privileges, Istina leverages her sociological knowledge and her control-type Arts to support Rhodes Island. A Supporter Slower Operator who deals Arts-based damage, Istina uses her spells to inflict DPS and to Slow the enemy’s advance.
Among the Slow-focused Supporter units, Istina stands out for her second Skill, Literature Storm. When activated, Literature Storm increases Istina’s ATK power, her range, and the number of enemies she can attack at once. Being able to Slow multiple targets over such a wide range can stop any enemy wave dead in its tracks, creating plenty of time for the rest of your team to pick the enemies apart. This power is bolstered by Istina’s Explorer Talent, which increases her attack speed, allowing her to apply her Slows more frequently and consistently.
Explorer does come with a drawback: it lowers Istina’s DEF, which is already one of the lowest in Arknights, meaning she needs to be protected in her placement. Her ATK is also noticeably lower than dedicated Caster Operators, reducing her direct damage potential. But despite her ATK, Istina can be an effective damage contributor in her own way because of her cheap DP cost, her large attack range, and her S2’s multi-target capabilities.

Increase Trust to 25.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.

Increase Trust to 50.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 amibitions extend only as far as Rhodes Island would be to underestimate her.

Increase Trust to 100.Istina was born in Chernobog, a city in the Empire of Ursus. Her parents were both employed in local agencies. During the periodi 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
Increase Trust to 150.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.

| Appointed as Assistant | Hello, I'm on duty right now. You don't seem happy about it... Do I look that unreliable to you? |
|---|---|
| Talk 1 | I'm not willingly putting myself on the battlefield... but none are as determined to survive as I am. It is my hope that you understand my sentiment. |
| Talk 2 | Zima, I, and the others all come from different schools, but one thing all schools have in common is that they know of Zima's reputation. She's widely known as the Winter General. A cool nickname, is it not? Literally... |
| Talk 3 | How did we escape from Chernobog? Um... you don't really want to know. Sometimes the truth is better left untold. |
| Talk after Promotion 1 | I'm reading a mystery novel... As a matter of fact, the things it taught me came in use when I fled that catastrophe. |
| Talk after Promotion 2 | What other genres do I read? Well, books on topics like politics, economics, and dialectical materialism... I also read magazines on making snacks. |
| Talk after Trust Increase 1 | My home? You mean where we came from? Obviously we can't go back there. You know as well as I do that there's nothing left there. Even if we rebuild Chernobog, I still... |
| Talk after Trust Increase 2 | Rhodes Island is safe. And there are so many books here in your office! If possible, I really don't want to leave... |
| Talk after Trust Increase 3 | What about the future? Mmm... No idea. The books didn't say. I hope someone will be able to tell me someday... |
| Idle | Whoa, I never expected this solution! "All the passengers on this train are murderers!" |
| Onboard | I am Istina. I'm still a student, but I'm able to use Arts, so I was recruited as a Caster... I know, it is rather strange for a student to be in a place like this. |
| Watching Battle Record | Do you want me to become stronger? |
| Promotion 1 | Do you feel like you understand me better now? Too bad... you actually don't know a thing! |
| Promotion 2 | I suppose I must cast a spell that turns this office into fine dust... I'm merely joking. There are too many valuable books in here for me to ever do such a thing. |
| Added to Squad | Got it. |
| Appointed as Squad Leader | The team... Hmm, it's somewhat different to what I imagined. |
| Depart | Let's show everyone our determination, earnestness, and burning 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 am not fond of the battlefield. |
| Deployment 2 | It seems we must fight. |
| In Battle 1 | Come here. |
| In Battle 2 | Please don't rush me. |
| In Battle 3 | Let's take things slowly. |
| In Battle 4 | It's time to teach you a lesson. |
| 4-star Result | Why do they fight... even though they may lose their lives? What do they gain from that? |
| 3-star Result | You want to praise us? Do it now, then! |
| Sub 3-star Result | Those enemies who fled... they probably won't be back again. |
| Operation Failure | It seems our efforts were not enough... |
| Assigned to Facility | Seems like a locked room where interesting things happen. |
| Tap | Mh?! |
| Trust Tap | It's too noisy here, I'd rather return to your office and read there, Doctor. |
| Title | Arknights. |
| Greeting | Hello, Doctor. |
