Celine

The subject can convert her own memories into Mania energy, recreating the scenes and physical components within those memories in reality. The fidelity and duration of the recreations are directly proportional to the importance of the memories consumed.

[Data Deleted]

She suffers mild corruption. Her mental state has been relatively stable for a long time, thus she only exhibits some degree of detachment from modern society and an obsessive conviction in her mission. She shows no significant physical signs of mutation.

The subject is the current Head Librarian of the Central Library of DisCity. Using historical research as cover, she covertly collects and compiles information that involves a large amount of highly classified intelligence. Further investigation reveals that, beyond her official duties, the subject has repeatedly made contact with an unidentified suspicious individual. She is also suspected of acting on their instructions to selectively preserve, alter, and distort historical records using her position of authority. Since her activities appear to serve the specific agenda of an unknown faction and could be exploited to destabilize society's consensus, immediate detention is recommended.

The subject hails from a family of official historians. She was once forced into exile, losing the right to record history. She later regained the position of Head Librarian after some arduous negotiations and restored limited freedom to continue her work. The alterations and distortions to historical records made during her tenure were in fact a survival strategy under extreme pressure. The pretense of compliance was a means of preserving the right and freedom to continue collecting and safeguarding authentic history. She later became an assassination target by the faction involved, sustaining severe injuries that resulted in complete memory loss. Current assessment: The subject's behavioral patterns have stabilized following the onset of amnesia, and her threat level has decreased significantly. Continued observation is recommended, with no further control measures required at this time.

The subject is an officially registered Sinner under the authority of Paradeisos. She was already on record prior to Chief's appointment, and has long been affiliated with the Central Library, working as a historian. While Chief was trying to learn more about DisCity's history, Schorl introduced the subject to Chief, and the two subsequently became involved in the investigation of the "Maris Andre" historical record tampering case.

She oversaw the day-to-day operations of the Central Library and had long been engaged in the collection and compilation of historical materials. Having traveled extensively to gather and organize documents from various periods, the subject produced bound records that restored the history of lost eras. While she rarely makes public appearances today, she remains highly reputed within academic circles.

She is gentle and reserved by nature, never one to provoke others. She possesses an excellent memory for historical documents and expertise in historiography, enabling her to efficiently authenticate materials and identify signs of tampering or fabrication. She has long been committed to uncovering and faithfully conveying historical truth, and holds zero tolerance for any deliberate distortion or falsification of historical records.

Her family had been history keepers since before Nightfall and had donated historical documents to help found the Central Library. The family was later struck by social unrest. Born a Sinner, the subject spent her early years in seclusion and was self-taught. But even after she escaped her confinement and went into hiding, her actions were always guided by her family's belief: Truth and knowledge should be made honestly and openly available to all.

Friendly by nature, she lends a hand to other Sinners whenever she can. However, her limited stamina means she can only carry light weights such as a single desk lamp per trip at an unhurried pace. By the time the rest of the team has finished their tasks, she might still be on her seventeenth trip, dragging out an otherwise quick mission.

When she attempted to use the kart racing simulator in the Recreation Room, the system threw two errors within three minutes due to excessive collisions. She then switched to a racing game, and the controller's buttons stopped responding before the end of the first lap. After the gym's bike also suffered a broken chain due to the subject, she has since been barred from approaching anything that resembles a vehicle.

Though she rarely initiates social interactions, she never turns down an invitation. Once, when asked by another Sinner to critique a poem, she agreed readily and read it carefully. With a smile, she ranked it among the top works of the Bureau's poets. However, that Sinner later learned that Raven was the only self-proclaimed poet within the Bureau, and has never gone back to Celine with another poem since.

She frequently offers Chief gifts such as amber specimens and fossils. During meetings, she also tends to ensure a comfortable room temperature for Chief. She has noted that these gestures do not stem from any recollection of her past preferences. Rather, she simply wishes that the gifts will remain by Chief's side for a long time, and that Chief will likewise remain by her side, sheltered from harsh weather.

[Celine repairs an old tome's page corner with tweezers.]

Celine: Chief, could you pass me the tool? If I move even a hair, I'll tear the page...

• Prompt: Hand over the adhesive
• Celine: There. All set. This fragile old thing survives another year. To celebrate and to thank you, shall I pour us some tea?
• Celine: 😏

• Prompt: Hand over the restoration paper
• Celine: Filling in what's missing is its own kind of inheritance. See? The page is damaged, but the words endure. As long as someone cares enough to restore them, history never really fades...
• Celine: 😏

[Celine sits by the window, reading.]

Celine: You're here. Did you already finish the book you borrowed? You read even faster than I expected.

• Prompt: ""Dusk of Nations""
• Celine: Good taste. But books only take you so far... If you want the deeper story, come by my place. I've collected materials with secrets the printed version never touched.
• Celine: 😏

• Prompt: ""A Brief History of Nightfall""
• Celine: Mm... curious about that dark chapter? The book softens it—reality was far harsher. Come sit with me, Chief. Let me read it to you.
• Celine: 😘

⚠ Living Search Engine

Christina is racking her brain trying to recall the title of a novel.

System Notifications: In the Bureau's reading nook, Christina paces in front of the shelves, visibly straining to remember a book.

Christina: I remember a detective novel about a wealthy man who vanishes with a fortune in Hypercubes... and in the end, the reader—meaning you—is the killer. What was it called again?

• Prompt: Ask Celine

Celine: *You Are the Killer*, by Angela P. Lorder.

Christina: Yes, yes, that's the one! Thank you, Celine!

⚠ Reading Craze

The once‑quiet reading nook has been seeing more and more visitors lately.

System Notifications: According to the report, the reading nook has had a notable rise in visitors, and average reading time is up as well.

• Prompt: Ask why

System Notifications: It seems I went through the entire collection, removed titles that no longer served their purpose, and reorganized the sections and displays.

⚠⚠ Natural Born Driver

Nino invites Celine to join her for a racing game livestream.

System Notifications: The Bureau is hosting an online tournament for *Ultimate Racing: Skyline*, and after enough pestering from Nino, Celine finally gives in and signs up.

Nino: Yes! A gentle, soft‑spoken Head Librarian paired with a technical gaming powerhouse like me—this tournament is going to be legendary!

Celine: The livestream does sound fun... I just don't have much confidence in my skills.

Nino: Relax! With me carrying us, first place is guaranteed!

System Notifications: In Nino's streaming room, the two pick up their controllers and get started.

Nino: Hahahaha! First place again, just as expected! Eat my dust! Celine, where are you?

Nino: Wait, you haven't even finished the first lap?!

Celine: Sorry... I'm not much of a driver. Apparently not in games either.

System Notifications: A flicker of dejection crosses Celine's face, and you decide to help.

• Prompt: Recommend a different game to Celine

Chief: How about *Death Rally: Violence Frenzy*? Maybe your driving talents will shine there instead.

Celine: ?

System Notifications: A month later, in the Bureau's online *Death Rally: Violence Frenzy* tournament, Celine takes first place with the highest Violence score.

⚠⚠ Nobody's Wrong

Celine's flawless memory makes her the perfect referee for a heated dispute.

System Notifications: Inside the Bureau, Roulecca and Dolly are arguing. Celine stands nearby, listening quietly.

• Prompt: What just happened?

Roulecca: Don't pin the armored car accident on me! I clearly heard Dolly shout ""left""!

Dolly: I didn't say that! I said there was an enemy on the left, so you should watch out. How was I supposed to know you'd yank the wheel and drive straight into a wall?!

Roulecca: Hmph. I heard it plain as day. Wait—Celine was in the car too. Let's ask her!

Dolly: Yes! Head Librarian Celine's memory never fails. She'll prove I'm innocent!

• Prompt: Hear what Celine has to say

Celine: I believe... neither of you misremembered. You simply interpreted the same call differently.

Celine: For future field operations, perhaps we could agree on this: the spotter reports enemy positions using clock directions only. How to maneuver from there is left to the operator's judgment.

Celine: That way, the call stays precise without prompting an instinctive reaction to the word itself. What do you think?

Roulecca: Not a bad idea! From now on, if you want Roulecca to shoot somewhere, just use that fancy lingo.

Dolly: Got it. Next time I'll call ""enemy at nine o'clock"" instead of ""left."" Roulecca, I—

Roulecca: No worries. Roulecca doesn't sweat the small stuff. Besides, the Chief's covering the repair bill for the armored car anyway, right?

Celine: What do you say, Chief?

• Prompt: Add Celine's suggestion to the protocol

System Notifications: You incorporate her suggestion into the Sinner field operations manual. According to the data department's feedback, mission success rates rise by about three percentage points.

⚠⚠⚠ Fireproof and Waterproof

Celine and Flora are deep in an animated conversation.

System Notifications: Several design blueprints are spread out before Celine and Flora, who are deep in discussion.

Flora: Containing the fire immediately while keeping the tomes intact... that's a tall order.

Flora: Inert gas suppression is one option, but parts of the Bureau aren't sealed well enough. Used carelessly, it could cause oxygen deprivation.

Celine: I once read about chemical agents that vaporize rapidly and absorb heat. Could rapid cooling drop the temperature below ignition?

Flora: You're on the right track! Beyond those agents, we could also consider a water‑mist system. It's less demanding on the environment, though there's still a risk of dampening the tomes.

Celine: If possible, I'd prefer the tomes come away without any water marks. Even the slightest trace would be a shame.

• Prompt: What are you chatting about?

Celine: Chief, we're discussing a fire suppression system suited for library areas—one that can fight fires while keeping the tomes safe.

Flora: The proposal is still in discussion. If you're willing to approve a modest research budget, I can run a small‑scale trial and see if it's worth implementing.

• Prompt: Approve the funding
• System Notifications: You approve the funding. The fire suppression system Celine and Flora developed works exactly as hoped, and the Bureau's server center adopts it as well.
• System Notifications: Celine later brings the proposal to the Central Library and secures a collaboration. The finance department sends its sincere appreciation for your discernment.

• Prompt: Reject the funding
• System Notifications: The Bureau's budget has been stretched thin lately. Somewhere in the corner, the budget sheet quietly weeps. So you let them down gently and decline the request.
• System Notifications: Celine eventually brings Flora's proposal to the Central Library instead—with the promise that if the research succeeds, the Bureau will be the first to benefit.

⚠⚠⚠ Bookplate

Celine is reading an Eastian seal impression catalog.

System Notifications: Celine sits at the reading nook table, several illustrated catalogs open before her. Her fingertip rests on a vermilion seal impression.

• Prompt: Ask what she's looking at

Celine: Oh, Chief. This is an Eastian seal catalog Yanyan brought for me. In Eastia, people carve their name, their study's name, or a motto into a seal, then press it onto their books.

Celine: Unlike DisCity's pasted bookplates, you stamp it by hand—a small, personal pact between reader and book.

System Notifications: On the desk sits a seal stone, a carving knife, and several draft sketches. She's clearly put a lot of thought into this.

Celine: I'd like to carve a bookplate seal of my own. I just haven't decided on the inscription yet.

Celine: Chief, would you help me choose?

• Prompt: Celine's Collection
• Celine: Celine's Collection... A traditional Eastian bookplate—simple and clear. It suits my work well.
• Celine: You know your Eastian culture, Chief. A fine choice.
• Celine: If you don't mind, stay a little longer? I'd love your thoughts on the carving style, font, and border.
• Celine: Having you help makes it all the more special.

• Prompt: Read Once, Remembered Forever
• Celine: Read Once, Remembered Forever... It's not about owning the tome. It's about carrying what you've read long after the pages close. A very Eastian sentiment.
• Celine: How does that saying go? ""Books pile up like mountains, but reading through them is like pulling silk."" Sometimes I get so caught up in collecting that I forget to actually read.
• Celine: A common affliction among readers, perhaps. So then, Chief... stay and read with me?
