Archon Quest
In Act 1, when Yoimiya and the Traveler is trying to save Master Masakatsu. Yoimiya decides to make a little distraction as she accidentally made a noise while trying to hide, which is by using her fireworks on the guards as the little distraction. She starts using the fireworks. Fortunately, it was successful, however, as the Traveler congratulates Yoimiya. Yoimiya tells the Traveler that she was proud of the batch and so more fireworks started launching. Paimon states Yoimiya that the fireworks are turning into a firework display, Yoimiya answers her, stating that every fireworks has to be spectacular.

In Act 3, the Traveler goes to Yoimiya again, asking her for her to make an extra-large firework for the distraction to get the proof. Yoimiya giggles as they came to the right person, but Yoimiya warns the Traveler to cover their ears and don't get too close to it because the firework is loud and still hasn't been tested. Then she gives the firework to the Traveler.

Quotes
"Fireworks are for now, but friends are forever."

- Yoimiya's Voiceline about Chat: Fireworks

"The loveliest fireworks go along with the most wondrous moments. Tiny little emotions that can easily slip away are captured within these fireworks and passed down in a different form. The notes we give our clients are like a key that awaits those who wish to open a gate to commemorate the past. We at Naganohara are the keepers of that gate."

"I shan't tell the final tale, I think. Instead, let's watch the fireworks together in silence. You can record the beautiful scenery and all the things you wanna say down. Not that this is the end, of course. On the contrary, I believe that our story is only just beginning."

I love playing with everyone!"
