In-game character attributes and profile page text

Yoimiya, like the rest of her family, is loved by the people of Inazuma City for the fireworks she creates. Like her father, Yoimiya is devoted to the family business, stating that her customers' happiness is the first priority above all else. This service has amassed a massive and loyal customer base who are willing to help her out on any problems she have.

She is also loved by children due to her friendly hands-on approach with them, as she wishes to keep them happy so they don't have to deal with the harsh realities of Inazuma for the time being. Having very few worries of her own, she can also read peoples' hearts and can tell whether or not they're hiding something deep down.

She is somewhat of a fast speaker, and despite being the primary provider of fireworks, is also known to be quite reckless and unprepared, having been scolded by the city's fire brigade numerous times and noted by Amenoma Tougo to always make last-minute preparations.

Like many other Vision bearers, Yoimiya enjoys her Pyro Vision, as it helps her out with the business and she couldn't imagine a life without one. While not supportive of the Vision Hunt Decree, she still worships Raiden Ei.


Yoimiya is a young woman of average height with a fair complexion. She has shoulder-length light strawberry blonde hair, tied into a high ponytail that messily sticks out in all angles. She wears many festival themed hair accessories. Her eyes are a golden color with orange-red makeup painted at the corners.

Yoimiya's attire mainly consists of a short orange-red kimono with only one sleeve worn. Her right sleeve is rolled up past her elbow and tied with a string. The left half of the kimono is draped around her waist. Her chest is wrapped up in sarashi, as are her left forearm and upper thighs, extending down to her right leg.

There is a small flower tattoo near her left shoulder above the sarashi, and another similar tattoo patch around her upper left arm containing a red fish, flowers, and purple swirls. A festival pouch hangs from her waist on the left, and her vision is secured to her obi on her right.

Official Introduction

Fireworks are the highlight of the festival, and Yoimiya is Inazuma's best pyrotechnician. Every display she planned turns out fabulously. Ah, right, do not worry about the fire hazards. The Yashiro Commission and shrine maidens will take care of the necessary precautions so that she can fully express her creativity.

A talented pyrotechnician. The current owner of Naganohara Fireworks known as the "Queen of the Summer Festival." She is a household name in Inazuma.

Various celebrations held in Inazuma City every year all have elaborate firework displays created by Yoimiya. She possesses an exuberant creativity and passion for firework displays that always leave people pleasantly surprised.

Yoimiya has a childlike innocence, and is often found playing simple yet timeless games with children or accompanying them to find shiny trinkets and toys. The purity of children brings her unparalleled joy.

She also enjoys social interaction and seizes every opportunity to talk to others. She appears to have endless anecdotes and ideas to be shared.

Principle and craftsmanship are Yoimiya's dearest qualities. Even though fireworks are fleeting, their blaze and warmth lives in people's hearts forever.

Both a moment and an eternity, these fleeting marvels are an expression of "protection" she gives to those around her.

It is because of everyone's involvement that the firework shows can carry on in such a beautiful manner.

Character Story 1

(Unlocks at Friendship Lv. 2)

To Inazumans, fireworks symbolize summer.

The various festivals that take place at fixed times feature a rotation of various events, with fireworks being the sole constant.

Over a century ago, the Yashiro Commission once organized a dazzling fireworks display with "commemoration" as the theme.

The fireworks then were made by the greatest pyrotechnicians in the land, and this was the origin of the Naganohara Fireworks Show.

In latter days, fireworks would become more common, and the Naganohara Fireworks Show would slowly become an event in which all people would participate.

During the Fireworks Show, everyone can light their favorite fireworks, and the owner of the Naganohara Fireworks store will pick an appropriate time to set up a most lavish performance.

The year Yoimiya took over, her first fiesta was already jaw-droppingly good.

On the night before that Fireworks Show, Kamisato Ayaka enjoined Yoimiya thusly: "Her Excellency will be watching this fireworks display personally. As such, please add Her Excellency's emblem — the Electro Mistudomoe — into the fireworks repertoire, if you would."

"Haha, just wait for it!" Yoimiya replied, agreeing with great confidence.

Before the show could begin, Yoimiya ran all about the city, placing thousands of launch tubes in every nook and cranny. At the festival's finale, the blazing fireworks formed a gigantic picture scroll that depicted the city of Inazuma in the skies.

Yet Ayaka did not find the critical emblem in any one of these fireworks, and wondered if Yoimiya had made an error in her arrangements.

It was only after speaking with Yoimiya that Ayaka discovered that the image of Inazuma in the skies had an "angling" trick added to it.

If viewed from the Tenshukaku, the fireworks would form a huge, clear, and orderly image of the Raiden Shogun's house-crest — with some playfully lacy decorations on the side to boot.

Of course, how could Yoimiya miss a beat at a fireworks performance? This way, she won the praise of both the people and the Raiden Shogun, and this feast would become a timeless classic deeply rooted in the memories of countless people.

With Yoimiya around, the Inazuman summer shall not lack any glorious fireworks — thus was her nickname, "Queen of the Summer Festival," coined.

Character Story 2

(Unlocks at Friendship Lv. 3)

Naganohara's fireworks are loved by all, and work in the shop is always in full swing. As such, people often feel that coming up to the door without important matters might hinder the work.

However, it's just the opposite with Yoimiya, for chatting is her other great hobby. In fact, if there's no one to talk to, she might actually find it hard to focus.

If chatting with the guest is her way of "understanding their mood and way of thinking, such that the best fireworks can be crafted," then going with the flow and sitting down for tea and an idle chat with them after delivering the goods is how Yoimiya rewards herself. Sometimes, if that is not enough, she will make some small-talk with her neighbors on the way, give them some small trinkets, and receive a basket of small treats in return...

Yoimiya is always able to strike a balance between listening and speaking in such chats.

She doesn't repeat herself, doesn't cross boundaries, doesn't come off as indifferent or overly invested. After a talk over tea, everyone leaves in a good mood.

Her neighbors are all ordinary folk, and their lives are not exactly full of extraordinary things. Sometimes, the same news will be told by different people over and over, but Yoimiya does not find this upsetting.

What she enjoys is the process of talking to others — even if they speak of the same matter, different people will have different viewpoints.

After taking over the fireworks shop, Yoimiya's relationships with her neighbors became still more harmonious. Many old folks have taken her for an old acquaintance, and often invite her to their place to sit and recount the festivals of yesteryear. Middle-aged parents will ask Yoimiya to mediate the relationship between themselves and their children and will regale her with the little trivialities of daily family life. The young people treat Yoimiya as a sibling of sorts, volunteering to help her cart heavy fireworks-making materials around, hoping that Yoimiya will get off work faster and take the children out to play.

Yoimiya puts it this way: "I believe in the unique power of language. There's nothing that can't be talked through somehow!"

Craftsmen seeking perfection are often rigorous and self-disciplined, but Yoimiya is an exception, acting freely and taking unscheduled breaks.

Sometimes, she even has to work late into the night when she misses her daytime work due to chatting for too long. But when the sun begins to rise, she will climb up to the heights to see the sunrise with a sense of accomplishment at having finished her work in her heart. Looking out at the hazy amber-gold clouds, Yoimiya often gains new inspiration, imagining all manners of new fireworks in her mind, even as sleep draws near...

Her neighbors have often found her sleeping in places like eaves, tree branches, and stopped waterwheels. Sometimes, she even falls down, before blearily watching her sweet dreams and golden stars fade away into the distance.

Fortunately, she has never been seriously injured in such incidents, but she has gotten a number of scrapes and cuts, and it was on that account that she learned how to deal with wounds.

At some other times, Yoimiya will sleep until midnight, settling all matters with gusto before heading out for a stroll.

Perhaps it may turn out to be an impromptu adventure, or perhaps a test of courage. If a friend is interested, she might call upon them. If she wishes to be alone, she will travel in solitude.

Living as she pleases gives Yoimiya a sense of freedom. As for others, they may encounter her at any time at all. She enjoys this freedom, often saying that it has made her life very interesting indeed.

Of course, she will restrain herself on the eve of celebrations. Mistakes shall not be made during these all-important performances — her "official business."

Character Story 4

(Unlocks at Friendship Lv. 5)

Apart from selling fireworks, Naganohara Fireworks also sells various intricate knickknacks. This can be said to be Yoimiya's second career.

All manner of trinkets adorn the shelves, with some of them being exotic imports from Beidou that were modified and made into highly distinctive handicrafts, and others being practice works created during bursts of Yoimiya's explosive inspiration.

From the Scatterbloom Marbles that will blossom when they knock against each other, Leaping Tops that chirp like birds as they spin, the Neon Dragonfly that changes hue as it ascends into the air, and the somewhat-failed Onikabuto Chariot... All these toys are inspired by the little games that the common people play.

They are not only popular among the children, but are much-loved by adults as well. Even Arataki Itto, the head of the Arataki Gang, comes over to buy her specially-made knickknacks, which he then brings to go challenge the one he has declared his nemesis.

Yoimiya's knickknacks are not just toys. With some thought, they can be very useful in one's daily life. The most classic example of this is the Katydid Coil, which is a ring that can contain a variety of flammables and spices. When ignited and hung up in the summer, it can be used to repel mosquitoes.

Many people have come to ask Yoimiya for help on account of her excellent craftsmanship. And though she protests, saying, "Hey now, this is a fireworks shop, not an everything shop. Even I can't possibly do it all," she will still try her best to help, even if her earnings for the whole day are only enough to buy a few snacks. She'll enjoy the whole thing, too — everyone in Hanamizaka is her friend, after all.

Character Story 5

(Unlocks at Friendship Lv. 6)

"The rainbows become fireworks, and they my wishes know, my wishes rise into the skies, and through the night they show."

This nameless folksong has been around for a long time now. In recent years, it was misconstrued by the children to mean that as long as they brought some shiny trinkets, they could exchange them with Yoimiya for fireworks that belong just to them, and that if they lit those fireworks up, their wish will come true at some point in the future.

As such, the children of Hanamizaka set about searching for beautiful little trinkets with this song on their lips, before bringing them to Yoimiya, with expectation eagarly written on their faces.

Yoimiya was quite troubled by this at first, but after hearing how the children had interpreted that song, she accepted their requests gladly and even added her own spin to the tale: the "rainbows" in the song not only refer to shiny treasures persay. As long as she found them "sufficiently shiny," whether they were colored rocks from the creeks or shell fragments from the beaches, she would take them and make lovely fireworks as per the agreement.

Indeed, if they were to bring her expensive things, she might, in turn, say that they are too ordinary, and take the child to look for the owner of those lost goods.

But it really did not matter if the treasures were shiny or not. The important part was the conviction the children had that "rainbows" could indeed be exchanged for "fireworks."

Though some might take it for naivete, Yoimiya will give her all to protect the lovely wishes that only children can have.

"The things we believed in and experienced as children become irreplaceable treasures."

The legendary picture books of Inazuma are often filled with the following images: the cute and playful Great Mujina Youkai, the majestic Shiba Warrior, the Origami Nue who appears out of nowhere...

Perhaps those who drew demons in such cute forms also had a similar intention to Yoimiya.

The children gather around Yoimiya, enjoying a gladsome time even amidst Inazuma's lockdown.

Yoimiya's own child-like heart and liveliness never dulls, like fireworks and stars that shimmer and shine in the night sky.

Yoimiya's Candy Box: "Sweet Pearl"

(Unlocks at Friendship Lv. 4)

Every festival, Yoimiya not only tries snacks from every store, but she also collects all sorts of candies, wraps them up with care, before storing them away inside a small candy box.

Yoimiya's candy box is a small crimson ball that has been decorated with delicate lanyards and ornate accessories, much like the hair accessories she often wears.

Each time she encounters a joyous event, she will take one candy out of the box and eat it. If her friends or the children are around, she will share the sweets with them.

Yoimiya's neighbors often mistake her hair ornaments for the candy box, hence its erroneous nickname "Sweet Pearl."

The speed at which the box lightens is taken for an important measure of happiness.

The quicker it empties, the more pleased Yoimiya is.

Sometimes, when things get busy, she sometimes absently uses the candy box as a hair accessory, realizing her mistake only after the day is done.

Still, even this error would inspire Yoimiya. From then on, she would wear them interchangeably.

"Take a guess: does my hair ornament have candy in it today? Free pick of the sweets to anyone who gets it right!"


(Unlocks at Friendship Lv. 6)

Yoimiya is always up for a chat. It is only when the fireworks are ascending into the skies that she quiets down and just watches the lovely scenery.

People often say that fireworks come and go in a fleeting heartbeat, but if they are memorable enough, they will remain in bloom forever in people's hearts.

Those who accompanied you and the loveliness of the moment itself, will burrow deep into your mind as a beautiful memory.

And as you look upon the same fireworks, many years later, that same memory and the feelings that came with it will surely rise again to the forefront of your heart.

Is this not also "Eternity"?

The special firework formula slips that belong solely to the Naganohara family exist for precisely this purpose.

By incorporating goodwill and wishes into the gorgeous fireworks, ephemeral things are etched into eternity. This is the meaning of Yoimiya's line of work.

On one summer night following her taking over Naganohara Fireworks, Yoimiya could not sleep, and thus she continued in her research till daylight came.

Suddenly, she heard a tinkling sound, and a burning-red object fell into an unused launching tube.

At first, Yoimiya used her Vision as a sort of lighter. Fortunately, her father discovered it and explained a Vision's significance to her.

So, this tiny gem could grant a person astonishing and mysterious powers. And yet what else could it do other than protect the children or chase some mischievous monsters away?

"Even if it could have other uses," Yoimiya thought, "it may not ever need to do these things in my hands. I'm just someone who pursues happiness, a fireworks-maker who enjoys living life."

Time has flown since then, and Yoimiya has grown ever more skilled in the manipulation of "fire," with her skill at making fireworks having likewise increased.

Sometimes, she stops to ask herself this: "How did someone as ordinary as me receive the acknowledgment of the gods? Do the gods... enjoy fireworks, by any chance?"
