Eureka

Her special power can change or enhance a material's properties, facilitating her invention process. Her weapon of choice is a specially modified screwdriver which she uses as a tool in daily life and as a slender sword in combat.

According to Eureka, she awakened as a Sinner several years ago when she accidentally touched Mania-tainted raw materials while manufacturing weapons in a black market workshop.

Physical examination results show that Eureka's level of corruption is low with no physical mutations, and all indicators are within the normal range. She is generally lucid and emotionally stable, with occasional fluctuations when recalling past experiences.

Originally from Eastside, Eureka has been dedicated to the research and manufacture of various eccentric inventions for years. Her contraptions are often hard to control and have caused numerous disturbances disrupting public order. Subsequent investigation revealed that an allegedly man-made explosion occurred in a suburban factory when Eureka was an employee there. As a major suspect, she was to be immediately detained and interrogated.

Upon interrogation, it was learned that Eureka didn't intentionally make the weapons that harmed innocent civilians but was deceived and coerced into doing so. During her detention in the MBCC, she proves to be sincere and kind, earning the favor and recognition of many within the Bureau. Under Chief's supervision and guidance, invention-related accidents have also significantly reduced. Eureka is evaluated to be no longer a threat to society.

Chief met Eureka at the Buonanotte Toy Factory. After the incident, she returned to the MBCC with Chief and willingly turned herself in without any resistance.

She is absent-minded and reticient, yet her mind is a playground of ideas with boundless imagination. She is obsessed with invention and creation, often traveling to various places in search of fresh inspiration. Beyond her string of novel yet impractical inventions, she seems to have a fair understanding of weapon development as well.

Born into a humble working-class family in Eastside, Eureka's childhood was rather stifling. With her parents' tough lives, they projected all their hopes onto her, frequently chastising her for mediocre grades and her penchant for handicrafts. Her school life was no different. Her eccentric hobbies earned her the label of a freak, leading to isolation and bullying.

During her university years, Eureka met her best friend Jessie. With aligned interests, they often collaborated on invention and research. After dropping out of school, she followed Jessie to work at her uncle's factory. It wasn't until she accidentally touched Mania-tainted materials and awakened as a Sinner that she realized the factory was in fact a black market weapon workshop. Unwilling to aid in the making of harmful inventions, she seized an opportunity to cause a disturbance and successfully escaped the factory.

Even after joining the MBCC, she's never ceased her invention. However, the constant noise from her room greatly disrupted the daily life of other Sinners in the Bureau. A small workshop was thus set up n a secluded corner specifically for her creative endeavors.

Despite not being a social expert, she is passionate about repairing things for others. With her handy skills, she can easily make any severely worn item brand new again. But she can't always resist the urge to modify all ordinary objects. Recently, the Bureau had to deal with the peculiar sight of self-rotating flying trash cans whizzing down the corridors.

Gentle and friendly, she rarely comes into conflict with others. Her dazzling array of novel inventions has piqued the interest of many Sinners and staff members. Some of the more generous Sinners have repeatedly funded the research for her new inventions.

It is roughly estimated that ever since joining the MBCC, Eureka has gifted Chief with a variety of special inventions, including an Emergency Ejection Chair, a Gesture Communication Watch, a pair of Lightning Escape Shoes, an Auto Strikeback Shield, and a Nightmare Catcher Helmet. Although most of these have never been put to actual use, she continues to pack Chief's office with new gadgets. This could be an awkward friendly gesture on her part.

[Eureka is browing a sci-fi movie magazine.]

Eureka: These props in the movies are intriguing... Hey Chief, got any movie gadget you want me to whip up?

Chief: ......

• Prompt: I want an invisibility cloak.
• Eureka: Let's see, if I mesh together some cameras and special screen fabric, it might just work... Oh, but covering the face is a tough one. It might end up looking like a solitary head hovering around. You cool with that?
• Eureka: 😉😉😉

• Prompt: I'm thinking a lightsaber.
• Eureka: Whoa! That's a cool idea! I've actually made something like that before. Had to keep the power low for safety — wouldn't even boil an egg... But it's got this nifty color changing trick.
• Eureka: 😫😫😫

[Eureka, busy sorting through a stack of travel pamphlets, glances up.]

Eureka: Chief, say you're planning a getaway... which route would you take?

Chief: ......

• Prompt: Definitely a laid-back journey with lots of downtime.
• Eureka: You know, travel's all about taking it easy and having the space to stop and think whenever a brilliant idea pops up... How about we do it together next time?
• Eureka: 😘😘😘

• Prompt: Vacations never last long enough; looks like it's gonna be a rapid-fire travel plan for me.
• Eureka: Oh right... you're always swamped, aren't you, Chief? Wait, I might have just the gadget to help you be more productive. Let me check...
• Eureka: 😖😖😖

⚠ Beware of the Black Market

We have to keep Eureka away from the Black Market.

System Notifications: Right after Eureka stepped into MBCC, she got roped in by the other Sinners and hauled off to the black market. She almost blew all her cash on what was rumored to be a piece of mythical meteoric iron—but, as luck would have it, it was just Summer's lab junk masquerading as treasure.

• Prompt: We should keep her away from the black market; she might get taken for a ride.

⚠ Greenhouse Exclusive

Eureka has invented a watering can specifically for the greenhouse.

System Notifications: One of the Sinners requested Eureka to devise a tool to boost watering efficiency. What she came up with was a 360-degree watering can that doused everything around it, user's switch-pressing arm included.

• Prompt: A remote control function would really hit the spot.

⚠ The Chef's Darling

Every cafeteria lady is smitten with Eureka, maybe even overly so.

System Notifications: Eureka regularly skips meals, lost in her world of inventions, but she's no food critic. She's unfazed by leftovers rejected by other Sinners for their less-than-stellar cooking. Thanks to this, she's the cafeteria lady's favorite, often rewarded with bonus sweet treats.

• Prompt: Eureka, a more balanced diet is better for your health.

⚠⚠ Practical Ingenuity

Eureka's breakthrough with the time-space travel device is all the rage.

System Notifications: Lately, we've picked up that certain Sinners are overstaying their welcome in the Training Room, way beyond what's permitted. Plus, there's a high overlap in their hangout spots. We need to check this out.

Chief: This many folks lingering in the training room for more than 10 hours? Something's not right here. When did they all suddenly get so gung-ho about training...

• Prompt: Go take a look and see what's up.

Chief: Looks like the spot's right here in this corner... Wait, is this gizmo new? I don't remember seeing it before.

Eureka: Hmm, is that someone walking?... Oh, it's you, Chief! Did you come to check out the time machine I've been piecing together?

Chief: Time machine... you mean this gadget here? Eureka, you're the brain behind this?

Eureka: Yep! It's been a hit this year! Used so much that it's starting to show wear and tear. Thought I'd drop by for a bit of tinkering and maybe tweak a few things.

Eureka: Perfect timing, Chief. I need your input... It's got massage and music features already. What do you think—should I go for a shaking option, or maybe an eject feature?

• Prompt: Ask for more details.

Chief: I haven't had a chance to try this machine out, so I can't really say. Eureka, how does this thing actually work? Does it genuinely travel through time?

Eureka: Absolutely. The first time I tested it, it kicked into gear before I knew what was happening... and when I opened my eyes again, it was the next day! It's pretty amazing...

Eureka: Others who've tried it have zipped a few hours into the future at least, and one even jumped a full day.

System Notifications: Leaning in for a closer look inside the machine, you see it's got just enough room for someone to stretch out, with a layer of dry, cozy velvet and dim lighting.

Chief: Wait a second, I've got a theory... Eureka, your music player, what's it playing?

Eureka: What, this? It's just some easy-listening tunes I snagged from the hypnosis room...

Chief: ...Just as I thought... Forget it, a hypnosis pod this potent is practically a time machine...

⚠⚠ The Makeshift Fixer

Faye's newly recruited "repair expert" seems to be constantly off her game.

System Notifications: Attention, attention! We've got a bunch of sketchy repair tickets cropping up in the Recreation Area. Please investigate soon.

• Prompt: Verify this alert.

Chief: Why am I getting these maintenance requests, and with an alarm, no less? Isn't this Faye's turf to handle?

System Notifications: Supervision System: It is presumed that some of the repair orders have been submitted repeatedly for several times in the past month, which triggered the system's anti-false reporting and quality control protocols.

Chief: So, these facilities have been breaking down a lot recently? Makes me wonder whether they're being mishandled, or if the repair team's skills are lacking... I hope Faye isn't skimping on the job again.

Eureka: It's obviously working fine... So why are there repair requests? That's bizarre...

• Prompt: Check with Eureka.

Chief: Eureka? Why are you here? Wait, are you the one fixing all the gear in the rec area?

Eureka: Yep, that's me. I've been working on the karaoke machine, the photo booth, and even the library door—all at Miss Faye's request.

Eureka: I've repaired them all, but people keep sending in repair requests, so I had to come and see for myself. But Chief, you see it too, right? Everything's functioning perfectly...

Chief: I'm still not sure what's going on. Maybe we should give the photo booth a whirl and see if it's actually working?

Eureka: Okay, firing it up... Ah, this pose works, selecting... See, this is my new tweak to the photo booth: a single button and the mechanical arm contorts you into your chosen pose.

Chief: Ouch, my back... Er, Eureka, you haven't been "upgrading" the other machines like this too, have you?

Eureka: Hmm? Chief, how did you know? Did word about the Sphinx trivia quiz on the library door handle become the talk of the town?

Chief: Well, not quite... I've figured out the reason behind all these repeat maintenance calls...

⚠⚠⚠ Dark Machinations

The Bureau appears to be in the crosshairs of a nefarious group.

Eureka: Blueprints... Where are those blueprints...

• Prompt: Call out to Eureka.

Chief: Eureka, can't find your blueprints? Need a hand searching for them?

Eureka: Oh, would you? That'd be awesome, thanks... It'd be a big help if Chief could join the search too. I put a lot of effort into those designs...

System Notifications: You and Eureka take different paths, each scouring a separate direction. It's not long before you spot Christina, lost in thought over a sheet of paper.

Chief: Christina? What's up? Hey, if you've got a moment, could you give a hand...

Christina: Hey, assistant! You're just in time! I've stumbled upon a wicked plot targeting our Bureau! Come on, let's team up and solve this mystery, bust these crooks!

• Prompt: Ask for more details.

Chief: A conspiracy against our Bureau? What's going on?

Christina: Check out this sheet. The design here looks like it's mapping out our Bureau! The blue zone on the left marks the safe areas with checkpoints, and these red zones on the right are under surveillance...

Christina: See this line? That's the path the crooks figured out for sneaking in! This sheet? It's the map they dropped after scouting the place! Well, what do you think? My detective work is pretty airtight, right?

• Prompt: Go along with her theory
• Chief: Impressive, as expected of a top-notch detective. What do we do now?
• Christina: Time to put Eureka's fingerprint gizmo to the test. Might uncover a clue or two... Hang on, it's glowing? What's going on here, is this print in the Bureau's records...!
• Eureka: What's this? A spotlight on me? Oh wow! My tiny ice cube design... Christina, was it you who found it? Incredible, just like a real detective...
• Eureka: When I've got the tiny ice cube ready, I'll hand one over as a thank you gift. It's super useful, perfect for keeping your drinks at the right temp... Look here, the blue and red bits are for temperature control, and these lines show where the power flows...
• Christina: Wow, who would've thought this was just Eureka's misplaced blueprint, and not something illegal... I mean, no big deal, really. It's just detective work!
• Chief: Turns out, it's a happy ending for everyone. Maybe it's better to keep their little secret under wraps...

• Prompt: Express doubts
• Chief: Wait a sec, didn't Eureka just misplace a blueprint? I bet it's one of her own sketches.
• Christina: Huh, really? But check it out for yourself, this paper doesn't look anything like a blueprint for an invention.
• Chief: That's a fair point, though I'm no expert on blueprint quality... Eureka's just around the corner, let's get her to take a look and clear this up.
• Eureka: That's my missing blueprint... Chief, you're amazing! I was worried I'd have to sketch out the mini ice cube design all over again...
• Eureka: Oh, by the way, the mini ice cube is a handy beverage temperature adjuster, for both cooling and heating... Look, blue for cooling, red for heating, and this line shows where the energy flows...
• Christina: Uh... Huh?
• Chief: No worries, Christina. This picture does have a... certain artistic flair. Not getting its original purpose isn't on you.

Work attire for engineers. Eureka modified it a bit herself. It can carry a large number of tools.

Don't stop exploring science. Only by moving forward can you find the answer to the truth.
