Yoimiya's name is renowned throughout Hanamizaka.

She is the most skilled pyrotechnician in Inazuma and is known as the "Queen of the Summer Festival."

Yoimiya, who has inherited the mantle of "Naganohara", is able to give people an unparalleled experience with her ever-changing and spectacular fireworks.

In addition to being a craftsperson, she is also the "heroic sister" in the eyes of many children. No matter how big the problem is, Yoimiya always has a solution to save the day.

Be it the illusions of fear or the shadows of cold reality, they will all dissipate under the starlight magic of Yoimiya's fireworks.

The children are not the only ones she helps — as long as one is willing to talk to her about their troubles, she will lend a helping hand, and try her best to help them through the crisis.

Splendid fireworks, warm starlight and passionate lights all join in a swirling dance in Yoimiya's hands. Her bright smile is always able to inspire fellow travelers and light up the way for them.

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 Mitsudomoe — 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.

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."

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.
