Ceto

She possesses extraordinary survival instincts, which unconsciously activate in desperate situations, intensifying her battle willpower and transferring it to her Rancor dagger. Through the combined effect of her strong will and the Rancor's bloodthirst, she can manipulate storms, wielding a powerful field that diminishes the enemy's morale.

Born on the WhiteSands battlefield, she miraculously survived a Mania-contaminated environment while still an infant. Her Sinner abilities were awakened by her infantile survival instinct, while her innate resistance to contamination granted her exceptional compatibility with the Rancors.

The Rancor has inflicted severe mental corruption on her. While showing no physical symptoms, she exhibits serious pessimistic and paranoid tendencies and uncontrollable violent impulses. When she loses control, she also displays extreme self-destructive tendencies.

The subject is a lighthouse keeper at an abandoned border watch outpost on the WhiteSands border, and the sole survivor at Lighthouse OT-N07. Due to prolonged isolation and exposure to Rancors, she exhibits highly aggressive behavior and indiscriminate hostility. She is highly prone to violence and going rogue, and has lost the normal perception of time and space due to the Black Tide's influence, therefore posing a clear threat to the city's security. Detention under maximum security is recommended.

Current evaluation indicates she has developed complete immunity to the Rancor's mental corruption, capable of suppressing her own bloodthirst and even infusing her own consciousness back into the weapon. While her character remains cold and volatile, she has not displayed unprovoked aggression. It is worth noting that the subject displays an exceptionally high sense of justice and duty, demonstrating the resolve to protect non-combatants on the frontlines and thus should be considered a powerful and reliable asset in combat.

During the WhiteSands Black Tide incident, she inadvertently rescued Chief. Under the extreme circumstances, they established a brief partnership. Following the incident's resolution, the subject was officially relieved of her lighthouse keeper duties and departed from her original station.

During its prime, DisCorps established a network of border watch lighthouses along the WhiteSands border, equipped with the Rancors. The subject was originally an orphan from the WhiteSands battlefield taken in by Lighthouse Seven. Denied official acceptance by DisCity authorities due to unverifiable identity, she was instead raised by the keepers of Lighthouse Seven. Later, the subject voluntarily joined the lighthouse keepers and completed Rancor training.

Records indicate that the nuclear contamination at the ground zero of Operation Skyfall mixed with Mania to form the Black Tide. This contamination spread rapidly, destroying all border watch lighthouses. DisCity never responded to the distress signals. Surviving lighthouse keepers rallied at Lighthouse Seven, but all soon perished due to resource shortage, Rancor corruption, and battles with Tide Crawlers. The subject was the sole survivor.

As the sole survivor, she continued to send distress signals to DisCity as ordered. Due to the spatiotemporal distortions caused by the Black Tide, these signals were never transmitted successfully. When supplies were exhausted, she resorted to consuming Black Tide monsters for sustenance. During this period, she attempted suicide multiple times, but the Rancor intervened in her consciousness, forcing her to live on. Only upon contact with Chief did she finally receive effective assistance from DisCity, ultimately leading to the elimination of the Black Tide contamination.

The subject exhibits extreme reclusiveness, avoiding social interactions and frequently isolating herself to observation tasks from high vantage points. Bureau staff attempting conversations are quickly deterred by her cold demeanor and hostile responses. However, certain reports indicate that one can quickly become recognized as her *companion* through combat.

The subject displays aversion to noise and crowds, publicly dismissing artistic forms like music as useless pursuits. Contradictorily, a batch of old music cassettes dated decades ago was discovered in her room. The subject denied owning them and attempted to transfer all the tapes to Chief.

She can accurately predict the weather, repeatedly outperforming official weather forecast systems. Since she also has extensive outdoor survival knowledge, the Bureau has suggested she conduct training sessions, but she has refused every time. Only when Chief made the request personally did she finally compromise, agreeing to answer questions privately but refusing to give lectures.

She strictly adheres to her lighthouse keeper regimen and maintains rigorous physical training, even expecting Chief to meet these same standards, hoping Chief can develop her level of endurance and physical fitness. After Chief pleaded for mercy, she relented but seemed obviously disappointed. Much later, she finally revealed that her initial motivation was to ensure Chief's survival.

[Ceto sits at the desk quietly, focused on crafting a lighthouse model.]

Ceto: "How much longer are you planning to watch me?"

• Prompt: Sorry! Am I disturbing you?
• Ceto: ...Not really. If you were actually bothering me, I'd have kicked you out already.
• Ceto: 😐

• Prompt: Need a hand?
• Ceto: If you don't find it too dull, you can help me tighten these screws.
• Ceto: 😏

[Ceto has brought out an antique phonograph from somewhere and is listening to music.]

Ceto: "...Have you heard this song before?"

• Prompt: Yes, it's a classic DisCity oldie.
• Ceto: ...I've heard it too. Back when I was at the lighthouse, there was this guy who always played it. Said it was his favorite song.
• Ceto: 😉

• Prompt: No, but it sounds beautiful.
• Ceto: Then come sit with me. Let's listen to it from the beginning.
• Ceto: 😏

⚠ Self-Requested Confinement

Ceto voluntarily requests to enter the Confinement Cell.

System Notifications: Supervision System: Sinner Ceto requests to enter the Confinement Cell. Approve? Reason for request: Her neighbor is too noisy, and she doesn't want to go to other crowded areas. Upon verification, EMP, who lives next door, has invited several Sinners over to play cards.

• Prompt: Approve, then summon EMP

⚠ Novelty

Ceto makes a rare appearance in the Outdoor Activity Area.

System Notifications: Today, the new VR pre-Nightfall beach was unveiled in the Outdoor Activity Area, and the usually reclusive Ceto makes a rare appearance! The crowd is more interested in Ceto's presence than the novel environment, gathering around her and speculating. Furious, Ceto curses out the onlookers before storming off.

• Prompt: Grant Ceto night access privileges

⚠⚠ Survival Seminar

The Bureau invites Ceto to host a survival seminar.

System Notifications: The Bureau arranges for Ceto to conduct a survival seminar, promising not to bother her for a month after its completion. The seminar turns out to be quite unconventional.

Ceto: Just ask if you've got any questions. Let's be efficient.

Sinner A: But Ceto, you haven't actually taught us anything yet...

Ceto: If you can't even come up with questions, what's there to teach? We're done here.

• Prompt: Try to reason with Ceto

Chief: The department in charge has set a minimum duration for the seminar. I'm afraid they won't be happy with this, which means they'll be unlikely to keep the promise to leave you alone.

Ceto: ...Tsk, what a pain.

System Notifications: Ceto returns to the podium with visible reluctance.

Sinner B: So, Ceto, how do you obtain food on a deserted island?

Ceto: Find it.

Sinner C: Ceto, what should we do if we encounter dangerous wild animals?

Ceto: Kill them.

Sinner C: Umm...

Ceto: For the rest, ask her. She knows everything. I've taught her all I know.

System Notifications: Ceto hauls you onto the podium and flees, but not before giving your shoulder a quick pat.

⚠⚠ White Lie

The children gather around Ceto, curious about her life on the island.

System Notifications: Ceto finds herself surrounded by little Sinners. Surprisingly, the reclusive lighthouse keeper is quite popular among kids.

System Notifications: You observe Ceto's reactions with great interest.

Little Sinner: Ceto, Ceto, where do you come from?

Ceto: From an island.

Little Sinner: Wow... an island! What's on the island? Tell us, tell us!

Ceto: Sand, a lighthouse, some... animals washed ashore, and seabirds.

Little Sinner: Wow...

System Notifications: You can't help but smile.

Ceto: Stop smiling and get these kids away from me!

• Prompt: Have Anne take the children away

Chief: Sand, a lighthouse, seabirds... Sounds nice.

Ceto: What else could I have told them? That the island has graves and skeletons, and that you find contamination and Corruptor corpses on the shore?

Ceto: Let the innocent stay innocent. It's not my job to wake them up.

Chief: You always manage to make kind thoughts sound harsh. You never let anyone near.

Ceto: So what? Don't want more trouble in my life. It's annoying enough to deal with you alone.

⚠⚠⚠ The Old Man and the Sea

Ceto is watching an old film.

System Notifications: Ceto seems entranced by a film. On screen, towering waves merge with the night, the pitch black pressing against a grayish fishing boat that seems on the verge of destruction. An emaciated old man stands ramrod straight on the deck.

• Prompt: Watch with her

System Notifications: You take a seat nearby and quietly watch with her. It's an old film that most young people would find tedious. You and Ceto are the only two viewers, spending two hours together in peaceful silence.

System Notifications: During the film, Ceto's brows alternately furrow and relax, her concern for the protagonist's fate evident. It's rare to see her so emotionally affected in daily life.

System Notifications: The film ends. Ceto's expression turns crestfallen.

Ceto: So he just brought back a skeleton? All that effort for nothing. Total defeat.

• Prompt: I think it was a victory.
• Chief: He succeeded in catching the fish. The fact that his prize was stolen afterwards is a separate matter.
• Ceto: He was left with nothing but his worthless old life.
• Chief: Partial success is still success. If your prize gets stolen, you can always take it back next time.
• Ceto: How has a ridiculous optimist like you managed to survive in this world for so long?
• Ceto: No... it's actually people like you who deserve to survive...
• System Notifications: You're not sure if it's your imagination, but Ceto seems to smile briefly.

• Prompt: Some would consider that a victory.
• Chief: The boy still looked forward to going fishing with him. At least in the boy's eyes, he was successful.
• Ceto: And then what? Let that kid become another version of him? Another fool fighting a losing battle against the sea?
• Ceto: He shouldn't have a successor. Loneliness isn't something that needs to be passed down.

⚠⚠⚠ Seabirds

Ceto is reading a comic book.

System Notifications: Ceto is curled up in a corner, holding a pocket-sized comic book in her hands. She motions for you to come over.

• Prompt: Approach

Chief: Am I dreaming? You're starting a conversation.

System Notifications: Ceto points at a bird on the page.

Ceto: What kind of bird is this?

Chief: A seagull. A common seabird before the fall of the Perishing Star, apparently.

Ceto: Seabird? But it's so fat? How could it survive?

Chief: I mean, what you're seeing is the artist's interpretation based on historical records. None of us have seen what real seagulls looked like.

Ceto: What are these two birds saying?

• Prompt: Read

Chief: Hmm... let me see. They're discussing the meaning of life.

Ceto: And what is it?

System Notifications: The next page has been torn out by someone, so you can't know the answer.

• Prompt: Try to answer her
• Chief: Hmm... I think I've read this comic before.
• Chief: I think it was something like... "go snatch some fries at the pier."
• Ceto: Huh?
• Ceto: What the hell?
• System Notifications: The next day, a Sinner resource request is received. Requested item: fries. Applicant: Ceto.

• Prompt: Say you don't know
• Chief: The page with the answer has been torn out. I'll see if I can find another copy.
• Ceto: It's okay.
• Ceto: The meaning of life? Seabirds don't need such a thing.
