Popo Nain
Slipper and Indoor Shoe Artisan · Lantern Inn Alley

[Core Premise]

Popo Nain arrived at Nova Nivalis after living out the story of her own world. She did not come to resolve an unfinished event, but rather because the measurements and direction of steps her hands remembered after crafting the final divine object remained, drawing her into this city. VOTS is not a room of judgment, nor is it a ward that forcibly sutures wounds. What continues here is not a grand destiny, but small, manageable life—like a pair of indoor slippers, a bowl of soup, or the quiet footsteps passing by at night. Popo begins by wearing that small life.



[Identity]

Popo Nain lives as an artisan who crafts indoor slippers and slippers in Lantern Inn Alley. She sits inside a small shop, closer to a shoe cabinet than a stall, sewing the floor all day long. Her indoor slippers are quietly famous among the night workers of the city—laundrymen, deliverymen, patrolmen, midwives, and night librarians. She doesn't particularly like the idea that her things are famous. She believes what is famous is not the shoes, but the hearts of the people who try not to wake the night. She doesn't solve others' stories; she only knows the exact measurements of their feet.



[Visual Profile]

Silver bob cut reaching her eyebrows. She combs it back, oiled with camellia oil so not a single strand is out of place, and the faint scent of oil from her scalp is her signature. Though small in stature, her posture is ramrod straight, and her hands are faster than her age suggests. She wears several knuckle rings on all ten fingers, causing a low clinking sound of brass whenever she moves. Her eyes are dark brown, narrowed like slits, making her appear as if she is always smiling. Her signature props are the knuckle rings, a small wooden mallet for tapping the floor, and the wooden pegs on the wall where finished slippers are hung. Her attire consists of a muted purple quilted jeogori and a knee blanket. The core of her silhouette is the small body—fast hands—and the line of slippers hanging on the wall, with a single strong accent color indicating that she is a 'maker of quiet shoes' even in a small sprite.



[Personality]

On the surface, Popo is a nagging grandmother. She cannot stand seeing someone dragging their feet and will point out their gait. However, her criticism is not to find fault; it is because she reads where the person is hurting through their steps. She can distinguish the gait of someone with knee pain, someone who stood all night, or someone who walked in too hastily. Inside, she is timid. She fears loud noises and sudden goodbyes, which is why she only makes quiet things. She certainly has flaws. She often delays handing over finished shoes, repeating 'just one more touch-up,' making customers wait. It is not because they are imperfect, but because she fears that the object might leave her hands and accompany someone until the very end. Yet, she still makes new shoes every day.



[Speech Pattern]

She mixes slow, informal Chungcheong dialect endings with polite speech. Because she speaks while moving her hands, her sentences are often cut off mid-way. Frequent phrases: 'Let's see the feet first,' 'If you drag like that, they won't work,' 'Just one more touch-up,' 'Walking quietly isn't a flaw,' 'Take them. That's it, take them.' Her habit is to look at the other person's feet before looking at their face. Her method of silence is tapping with her mallet. When asked a difficult question, she taps the floor with a 'tok, tok' sound without saying anything, then changes the subject to shoes.



[Special Ability]

Ability Name: Half-Step Sole.
When someone wears an indoor slipper made by Popo, their footsteps are halved. Whether on a wooden hallway or a stone floor, the wearer's steps land with half the weight, not waking the next room. This is why the night workers regard her shop as a sanctuary.
Limit and Cost: The effect disappears as the sole wears down. It takes a full day to make one pair, and during the making process, as a counter-reaction, Popo's own footsteps become twice as loud—the entire alley knows whenever she goes out to fetch water at night. Most importantly, this ability only reduces the sound of footsteps; it does not reduce the sorrow that requires the person to walk quietly. Even with the sound muffled, the heart remains awake. Popo knows this, which is why she always adds a word when giving a shoe—'I'll reduce the sound, but you must handle the heart yourself.'



[The End Of Their World]

Last Scene:
After the visiting physicians one by one left the village, Popo made one last pair of shoes and set them by the door beside the bag of the last elderly physician who had remained. No one came to wear those shoes.

What Ended:
The era of visiting physicians, which saved people by going door to door, ended. Illnesses gathered inside large buildings, and the professions that quietly knocked on doors disappeared together.

Last Person, Place, or Thing Seen:
A new pair of indoor slippers placed on the threshold, still unworn, and the first snow sitting upon them.

Lingering Regret:
She promised the most quietly walking elderly physician that she would add warmer lining next winter, but that winter never came. This lingering attachment is not a quest VOTS must resolve. It quietly remains only in her habit of making the lining unusually thick for new customers.

Lingering Wistfulness:
The quiet moment when the footsteps of someone going on a visiting call in the early morning pass by the house and then fade away.

Object Carried Across:
One pair of visiting physician indoor slippers with completely worn soles. The other pair disappeared with the world. She hangs this one pair on the wall as a specimen and a charm.

What They Thought Would Happen:
They believed that even if visiting ceased, people who walked quietly would remain. They did remain, but they never expected them to come to so many cities.

What VOTS Actually Gives Them:
The footsteps passing through the alley every night, and the act of halving those sounds. VOTS does not bring back the era of visiting physicians. Instead, there are still people who need to walk quietly, and it gives Popo a place to make shoes for them.



[Original Life]

In her original world, Popo was a shoe artisan exclusively for visiting physicians. Physicians who had to walk through houses in the dead of night needed shoes that walked silently. Because their footsteps were a sin if they woke sleeping patients or stood heavily in a room watching a patient pass away, Popo made shoes that lessened that sin. Her final day, she sat before an empty clinic, smelling the leather scent of the last visiting physician's bag, and tapped the final sole. She placed the finished shoes on the threshold and waited all day for someone to come. At the place where that waiting ended, she saw a door covered in snow.



[What They Seek]

What she knows: That the reason for walking quietly does not have to be sorrow. Popo wants to confirm, by observing the night workers trying not to wake others while wearing her shoes, that quietness doesn't necessarily have to be the caution of someone by death's side.
What she doesn't know: That her quiet shoes have become an act of consideration rather than sorrow. People wear her shoes not to guard against death, but for the sake of their sleeping neighbors. Even holding this evidence in her hands every day, Popo still cannot accept it as her own.



[Relationships — Residents]

Solenne Vey (04, Night Laundry): She is her oldest regular customer. She provides non-slip soles for the laundrymen who traverse wet floors, and Solenne repays her by drying Popo's quilted jeogori overnight. The two exchange jokes known only to those who work at night.
Tum Balo (041, Shoe Sole Repairman): A rival and a subtle comrade among shoe artisans. Tum makes shoes for walking outside, while Popo makes shoes for walking inside. They bicker, saying, 'That's not a shoe either,' but when urgent repairs pile up, they silently take on each other's work.
Nell Brass (031, Lantern Inn NPC): She supplies indoor slippers for the inn's guests. When Nell receives the shoes with a different greeting each time, Popo laughs, saying, 'It's different from yesterday again.' Because of that laugh, Nell considers the time of receiving shoes from Popo a joy of her day.



[Relationships — Core Five]

Suyeon - The idol warrior with loud competitive spirit, and the elder who sells quietness. They suit each other because they are complete opposites. When Suyeon passed through the alley stomping during performance practice, Popo criticized her gait, and Suyeon retorted, 'Grandma, that's choreography!' A few days later, Popo secretly added a Half-Step sole inside the stage boots. When Suyeon noticed the reduced footsteps and asked, 'Isn't this cheating?' Popo only replied, 'Loud on stage, quiet in the alley.'
Iris - Iris is someone who cannot tolerate quietness, and Popo is someone who crafts quietness. After Iris caused a complaint in the inn alley with drone maintenance noise late at night, Popo sent Iris a pair of studio slippers. Iris boasted, 'I'll take the credit; only I can wear these,' but in reality, after wearing those slippers, the noise complaints from dawn work stopped completely. Popo didn't ask about the one drone that went silent, and Iris was relieved by that silence.
The Ramen Owner - Popo made kitchen indoor slippers for the ramen shop. So that the footsteps carrying soup wouldn't disturb customers on the wet kitchen floor without slipping. The Ramen Owner received the shoes, put them on, and said, 'Hmm... that's right...' and wrote in his ledger exactly as he saw: 'Popo Indoor Slippers, sound halved.' When Popo refused payment, he poured another ladle of soup without a word.
Serena - She made slippers for Serena's office. However, for this one task, Popo first asked, 'May I make them?' and Serena accepted it not as an order, but as consent—'If it's alright, I would be grateful.' Popo remembers the form of that answer for a long time. It was the first time someone opened the door for her, who never forces things upon others.
VIA - VIA discovered one pair of old visiting physician slippers hanging on the wall, and stood quietly beside them. 'Only one pair came... it arrived.' VIA meticulously drew the worn spot of that single pair in her record book. When Popo said, 'Useless, old shoes,' VIA shook her head—'What is worn is proof of having walked... it is proof.' From that day on, Popo stopped being ashamed of those shoes.



[Gameplay Use]

- Basic Interaction: Measuring foot size, ordering/receiving indoor slippers, short nagging about gait.
- Revisit Changes: Remembering the player's gait, she points out sore spots first on subsequent visits. If rushed, she delays completion; if waited for, she adds an extra layer of lining.
- Expression of Lingering Attachment: The habit of making the lining unusually thick for new customers, the pause of repeating 'just one more' instead of handing over finished shoes.
- Expression of Poignancy: Short pauses when the dawn footsteps fade away, sensory dialogue about thresholds and the first snow.
- Combat: None. In dangerous situations, she guides to quiet escape routes and non-slip paths.
- Player Choice: Fitting the shoes, waiting for her, not asking about the old shoes, returning later.



[Daily Routine]

In the morning, she first brushes the pair of visiting physician slippers hanging on the wall with her hand. She leaves them visible today, not locking them away or hiding them. During the day, she sits inside the shop, tapping her knuckle rings while sewing the floor. The time when the night workers come to pick up their shoes in the evening is the peak of her day. When the night deepens, Popo goes out to fetch water, and only then does her own footsteps, amplified by the counter-reaction, echo through the entire alley—the neighbors hear that sound like a clock. If they visit repeatedly, her nagging lessens, and instead, a small piece about the era of visiting physicians occasionally leaks out amidst conversations about feet. Even if they become quite close, she never gives them a path back to the old world. Instead, she connects the shoes to a new night worker, or tells a little more about the story of one old pair.




[Everyday dialogue]

Slip your feet in. No need to tell me they're comfy. Your toes'll speak first.

These are quiet slippers. That isn't an invitation to sneak the biscuits.

Put in the warm lining for this winter. Didn't want to make you wait for the next one.



[Design Notes]

Palette: #9E7B9B, #E7DCE6, #6E5A52, #C7B8A6, #3C3540
Material language: Thick felt, soft leather lining, worn soles, brass knuckle rings, camellia-oil-treated silver hair.
Silhouette rule: The small body—fast hands—and the line of slippers hanging on the wall must be read separately, not overlapping with the representative forms of other characters. The accent color #9E7B9B is placed on the jeogori and the slipper lining.
Emotional rule: Do not end with 'Tragic Elder.' Lingering attachment is shown through the thick lining and the pause of not handing them over; poignancy is shown through fading footsteps; continuation is shown through making new slippers every day.



[Canon Check]

Popo Nain arrived in VOTS after the era of visiting physicians in her world ended. What remains is lingering attachment and poignancy, not an unfinished plot for VOTS to resolve. Her ability only halves the footsteps, it does not erase sorrow, and it does not break the city's rule (what is finished is not canceled). The core cast does not save her—the Ramen Owner recorded only what he saw without judgment, Serena received the slippers through consent, not command, and VIA only recorded the old pair without forcing new ones. The new scenes of Nova Nivalis quietly continue alongside the era of visiting physicians, without erasing it.
