Every Summer 20th the Fireworks Festival is held. Starting on the 17th up to the day of, you can invite any of the marriage candidates. They must be at at least bond level 5. If you are already married, you can only invite your spouse. At 7pm you can find them on the beach on the right side of the village.

The morning of the Fireworks Festival Woolby will mention going to see Matsuri at the Summer God Shrine. Between 10am and 5pm speak to her to make a special firework for your date. She'll ask you for an item that will determine the color of your firework and then ask you to pick a size. There are six different colors (blue, green, orange, purple, red, and yellow) and three different sizes (medium, large, and deluxe). Your date will have one of three reactions to your firework; neutral, like, or love which will earn you 25, 35, or 45 bond points respectively. If you fail to speak to Matsuri, you and your date will see a generic firework and only earn 15 bond points.

Below are some easy to use items for each color of firework:

• Blue: Material Stone, Soil, Ores
  
• Green: Thread, Horns, Catalysts, Powders
  
• Orange: Scrap Metal, Furs, Fangs
