The sun rose over the Jura Forest, casting warm rays across the shining city of Nyvaris. After the announcement of the celebration, Rimuru—now a beloved king and architect of joy—oversaw the preparation of thousands of golden-engraved invitations.
While the official invitations were sent to the great allied nations of Dwargon, Raja, Filtwood, Siltrosso, and Sarion, messengers traveled far beyond those borders. Just like during the Festival of Harmony long ago, no one was left out.
Carriages made of shimmering silver and powered by floating magic stones departed from Nyvaris. They appeared in every nation, every city, and even small villages, inviting everyone to come witness a celebration unlike any the world had seen before.
Children in Filtwood squealed in delight as they saw the enchanted carriages land gently near their village square. In the rocky capital of Dwargon, soldiers paused their training as a beautifully armored messenger handed Gazel the royal scroll. In the golden deserts of Raja, caravans of travelers began preparing their finest attire.
And in the floating towers of Sarion, Queen Elmesia—Varvatos' lover—smiled with grace as she stood on her palace balcony, watching her people board the carriages with excitement.
Elmesia (smiling):
"Nyvaris… you've become the heart of the world."
The gates of Nyvaris opened wide as the first carriages began arriving.
People gasped in wonder the moment they stepped out. Towering crystal structures reflected the sunlight into glowing rainbows. Floating gardens moved gently through the air, trailing soft music and flower petals behind them. Magic lanterns filled the skies like glowing orbs, changing colors with the wind. Rivers of silver water ran through the city, crossed by gently arching bridges that hummed with energy.
Child from Siltrosso:
"Mama… is this heaven?"
Old man from Raja (chuckling):
"No, child. This is Nyvaris."
Rimuru had transformed large districts into themed celebration zones, each resembling a magical amusement park. Some were inspired by his memories of theme parks from another world—complete with rides, magical roller coasters, candy-colored buildings, and dancing mascots.
Rimuru (grinning as he watched people enjoy themselves):
"This time, no one will miss out."
As the sun reached its peak, the sound of trumpets echoed across the city. Varvatos, Velzard, and Elmesia appeared on the central stage in a plaza large enough to hold hundreds of thousands. Behind them stood Rimuru, Benimaru, Diablo, Testarossa, Ultima, Carrera, and the other Demon Lords.
Varvatos (his voice filled with divine calm):
"Today, we do not celebrate just a victory. We celebrate life. We celebrate unity. And above all… we celebrate peace."
A wave of energy spread from him like a ripple in space, soothing and gentle. The crowd erupted into thunderous cheers.
The Park of Dreams, one of the festival zones, became a favorite among children. There were rides that let people fly through floating rings of light, mazes made from singing hedges, and enchanted puppet shows that danced in the air.
The Courtyard of Flavors was where everyone went to eat. Food from every corner of the Cardinal World was available. Stalls were run by cooks from Raja, chefs from Sarion, dwarven bakers from Dwargon, and even Rimuru's own slime-themed food booths, which sold Gelato Slime Cones and Tempest Tornado Ramen.
Testarossa (delicately tasting a fruit tart):
"Rimuru-sama, this is… divine."
Rimuru (laughing):
"Well, I did help with the recipe!"
Carrera (already on her fifth plate):
"No regrets. I'm eating everything."
Elmesia walked hand in hand with Varvatos through the garden paths. The two stopped at a pond where flowers bloomed in the air like butterflies.
Elmesia (resting her head on his shoulder):
"They needed this. We all did."
Varvatos:
"It's a beginning. One of many."
From noblemen in silk robes to goblin children chasing fairy lights, everyone was welcome. The Demon Lords, usually intimidating to the world, danced and drank with strangers. Milim competed in pie-eating contests (and won), Guy Crimson silently sipped tea in the noble section while surrounded by curious admirers, and Draguel gave flight rides to young kids using his dragon form.
Even the Warden Beast, once a terrifying presence, now roamed the park wearing a bowtie and letting kids climb on his back.
Benimaru (laughing as he watched):
"Didn't expect this after fighting a cosmic evil, huh?"
Diablo (grinning):
"I must admit… it's refreshing."
On the final night, the skies above Nyvaris lit up with celestial fireworks, each one created by Rimuru and Varvatos. They painted images in the sky—scenes from the battle, symbols of unity, the emblems of every kingdom, and finally…
A portrait of Varvatos, Elmesia, and Velzard together—standing hand in hand as the protectors of this new age.
People wept. Some cheered. Others simply held onto each other and stared in awe.
Young girl from Filtwood:
"I want to be like them when I grow up."
As the third day ended and the final lights faded, Varvatos stood once again at the heart of the city, looking over the crowd. Rimuru stood beside him, a proud smile on his face.
Varvatos (quietly):
"They will remember this."
Rimuru:
"They'll remember that hope always rises… even after the darkest night."
And with that, the celebration came to a close—but its spirit would echo through the Cardinal World forever.
