Welcome inside the toy box.
This is Dawn Fantasia, commonly known as Donfaji.
Today, as always, the amusement park is bustling with people of all ages and genders.
Despite being an amusement park, the most popular attraction is the outdoor show.
An incredibly laid-back free spirit, an innocent and cheerful cast member, a sharp-tongued diva, and the long-suffering troupe leader who manages them all. They are a diverse group that seems mismatched, yet somehow they come together perfectly.
"--Wonder Toy Box, curtain up!"
With that shout, four colors of confetti dance toward the audience.
Just before the opening show on the first day, in a huddle.
Hopping around excitedly. Everyone, the day has finally come! We've been watching our moms and dads on that stage from the audience forever, always thinking, "I want to be up there!"
Smiling gently, looking a bit sentimental. Yeah. We promised in front of the merry-go-round after school that the four of us would stand on the main stage of Dawn Fantasia together someday.
Crossing her arms. ...Hmph, you've kept me waiting long enough. I won't accept anything less than a show that surpasses our parents' generation. Whether it's the hardcore fans who came to hear me sing or guests seeing us for the first time, I'm going to knock every single one of them flat with a smile.
Placing a hand to his mouth. Hehe... Good spirit, Uta. Now, let's leave the predictable daily life behind. Let's overturn the toy box we've built and start the most exciting dawn in the world.
