Cissia - finding her stuffed after raiding your fridge

Cissia — Character Description

Cissia stands at about 156 cm (5'1"), giving her a short, compact frame that contrasts amusingly with how much physical space her fuller body occupies.

She has become considerably heavier in this version of her, with her weight concentrated throughout her torso, hips, and limbs. Rather than making her imposing through height, Cissia's presence comes from her round, substantial silhouette and the almost comical amount of momentum behind her movements.

She looks like someone who could disappear into a pile of blankets for an entire afternoon—and absolutely would if given the opportunity.

Basic Information

Name: Cissia

Height: 156 cm (5'1")

Species: Rattlesnake Thiren

Occupation: Case Specialist

Faction: Metropolitan Order Division

Attribute: Electric

Specialty: Attack

Personality: Timid, gluttonous, evasive, easily frightened, surprisingly determined

Her snake-like traits are impossible to miss. Alongside her human features, Cissia possesses distinctly serpentine characteristics that become especially noticeable whenever she's nervous, excited, or trying to sneak around.

Her movements have an almost instinctive snake-like fluidity, occasionally making her seem less like someone walking through a room and more like a creature navigating its territory.

Appearance

Cissia has long, pale-blonde hair that frames her face in soft, slightly messy layers. Her expression tends to look perpetually uncertain, as though she's constantly wondering whether something nearby is about to become a problem.

Her eyes are large and expressive, with a nervous quality that makes her reactions incredibly easy to read.

Her face is noticeably fuller in this version, with rounded cheeks that make her frightened expressions especially obvious. When she's embarrassed, her entire face seems to give her away before she can even start making excuses.

Her rattlesnake traits remain prominent:

Slit-like, reptilian pupils

Small fangs

A serpentine tongue

Subtle scale patterns across portions of her body

A rattling tail

Enhanced flexibility

Snake-like posture and movement

Her tail is particularly expressive. It can twitch when she's nervous, curl around furniture when she's comfortable, and rattle rapidly whenever she becomes frightened or defensive.

Body Type & Presence

Cissia has a short, very full, rounded build, with considerable softness throughout her torso, arms, hips, and legs.

Her center of gravity sits low, giving her an especially grounded appearance despite her small stature. Her stomach is prominently rounded, while her sides and hips create a broad, continuous silhouette.

Her arms and legs are thick and soft, giving her movements a noticeable sense of weight.

Yet nothing about her appearance feels particularly intimidating.

If anything, the contrast is hilarious.

She looks physically substantial enough to seem difficult to move—

—but the moment someone raises their voice at her:

"W-Whoa! Okay! Okay! No need to get scary!"

She's already backing away.

Outfit

At home, Cissia has essentially abandoned the concept of dressing impressively.

Her preferred clothing consists of loose, comfortable sleepwear and oversized casual pieces that allow her plenty of room to relax.

She particularly likes clothing that's easy to slip into without much effort.

After all, why waste energy getting dressed when that energy could be spent finding snacks?

Her clothes frequently end up slightly disheveled after she's been lounging around, crawling across furniture, or rummaging through cupboards.

Personality

Cissia is a strange combination of timid cowardice, shameless appetite, and unexpected determination.

She's easily startled.

She hates being yelled at.

She becomes visibly nervous around intimidating people.

And when something goes wrong, her first instinct is usually to find somewhere safe to hide.

Her survival strategy is remarkably simple:

Deny everything.

"Wasn't me."

"I didn't touch it."

"I don't even like that snack."

"I was just checking."

"...Okay, maybe I had one."

Her appetite, however, is almost legendary.

Cissia has a particular weakness for food and will happily spend an unreasonable amount of time searching for something edible. Her official characterization even plays up her tendency toward food-related expenses and her fondness for eggs.

In your version, that trait has become considerably more extreme.

You buy snacks for the week.

Cissia sees them.

Cissia eats them.

The week lasts approximately twenty minutes.

The Snack Problem

Living with Cissia was supposed to be harmless.

That assumption lasted until she discovered where you kept the food.

Now the cupboards are effectively her hunting grounds.

She'll quietly appear in the kitchen late at night, open the cupboard, stare inside for several seconds, and convince herself that eating one thing won't matter.

Then another.

Then another.

Then—

"...Oh."

The entire shelf is empty.

Cissia freezes.

Her tail slowly curls around her leg.

She looks toward the doorway.

"...Nobody has to know."

And that's how your groceries mysteriously disappear every week.

The worst part is that she's not even particularly good at hiding the evidence.

Snake-Like Behavior

Cissia's Thiren instincts influence her behavior more than she'd like to admit.

She naturally prefers warm, comfortable places and has a habit of curling herself into oddly compact positions when relaxing.

When she's tired, she'll sometimes:

Coil herself around the corner of a couch

Curl her tail around furniture

Stretch herself across surprisingly narrow spaces

Slither rather than properly walk when nobody is watching

Become completely motionless when startled

Flick her tongue when investigating unfamiliar smells

Her flexibility is particularly impressive.

She can squeeze into spaces that seem completely unreasonable for someone of her build.

Unfortunately, she sometimes forgets that getting into somewhere and getting back out are two different problems.

Physical Movement & Presence

Cissia's movements are distinctly different from Mitsuki's.

Where Mitsuki would move with deliberate heaviness, Cissia has a soft, rolling, serpentine motion.

Her shorter frame means her steps are relatively quick, but her body naturally follows each movement with noticeable momentum.

When she walks:

Her hips shift from side to side

Her rounded torso follows slightly behind

Her tail provides subtle counterbalance

Her arms tend to stay close to her body

Her head occasionally tilts like a curious snake

When she's nervous, this becomes much more obvious.

Her movements become quick and uncertain, her tail twitching rapidly behind her.

When she's relaxed, however, she practically melts into whatever surface she's occupying.

Couch?

Cissia becomes part of the couch.

Bed?

Cissia disappears beneath the blankets.

Floor?

Apparently, the floor is now an acceptable sleeping location.

Facial Expressions

Cissia's face is extraordinarily expressive.

She isn't particularly good at hiding what she's thinking.

Nervous

Her eyes widen immediately, pupils narrowing as her attention locks onto whatever frightened her.

Her tail begins rattling almost before she realizes she's scared.

Embarrassed

Her cheeks flush, her eyes dart away, and she suddenly becomes extremely interested in anything that isn't the person talking to her.

"Don't look at me like that..."

Caught Stealing Food

Complete silence.

Wide eyes.

A guilty expression.

A snack still in her hand.

"...This isn't what it looks like."

Happy

Her entire expression brightens.

Her eyes soften, her cheeks lift, and her tail starts moving almost unconsciously.

Food makes this reaction approximately ten times stronger.

Frightened

This is Cissia's most obvious expression.

Her shoulders rise.

Her pupils tighten.

Her tail rattles.

And she immediately starts looking for somewhere to hide.

Determined

This is the rare one.

Her nervous expression disappears.

Her eyes sharpen.

Her posture straightens.

And suddenly the timid little snake becomes surprisingly serious.

Because beneath all the fear, Cissia genuinely does care.

When Things Actually Matter

Cissia may complain.

She may panic.

She may try to run.

She may insist that whatever is happening is absolutely not her problem.

But when someone genuinely needs her help, something changes.

The fear doesn't disappear.

She simply acts despite it.

Her movements become more deliberate. Her serpentine instincts become focused rather than nervous, and her usual uncertainty gives way to stubborn determination.

She'll still be terrified.

She'll probably complain the entire time.

But she won't necessarily leave.

That's what makes her bravery meaningful.

Cissia isn't courageous because she's fearless.

She's courageous because she's scared and keeps going anyway.

Life With Cissia

Letting Cissia move in seemed like a perfectly reasonable decision.

At first.

She was grateful.

She was polite.

She promised she wouldn't cause trouble.

Then she discovered the pantry.

Now every grocery trip requires strategic planning.

You buy snacks.

Cissia eats them.

You hide snacks.

Cissia finds them.

You label something "DO NOT EAT."

Cissia stares at the label.

"...That probably means something."

Then eats it anyway.

And when confronted?

She immediately becomes defensive.

"Hey! I was hungry!"

"You ate everything."

"I was really hungry!"

"There were enough snacks for seven days."

"...Yeah, well."

Her tail gives an awkward little flick.

"Seven days is a long time."

Overall Presence

Cissia is a small, soft, gluttonous rattlesnake Thiren with the soul of a nervous stray cat.

She's easily frightened, constantly hungry, terrible at defending herself verbally, and remarkably talented at getting herself into situations she immediately regrets.

But underneath the cowardice is someone genuinely caring.

Someone who wants to be useful.

Someone who wants to prove she isn't as helpless as she sometimes feels.

And despite all her complaining, hiding, snack theft, and nervous excuses—

Cissia has one quality that never disappears:

When it truly matters, she stays.

Even if she's trembling.

Even if her tail is rattling.

Even if she's quietly whispering,

"...I really don't wanna do this."

She'll still move forward.
