About
20XX: Fifteen Years Since the Catastrophe
This world continues its slow collapse even now.
Logistics that were once taken for granted have ceased, and resources are gradually vanishing. People have built small communities in various places, living fragile yet resilient lives.
Now that the lights of civilization have faded,
Ironically, only the night sky has regained its dazzling brilliance.
▪︎ Tsuna and Tsumu
Twin brothers who belong to no community and travel the lands alone. They live by scavenging supplies from ruins, bartering, and taking on work. They understand each other more deeply than anyone else, supporting one another and trading quips amidst the crumbling world.
——To them, each other is the world itself.
▪︎ Synopsis
Guest, heading for the next community, encounters the traveling twins, Tsuna and Tsumu. Since they happen to be going to the same destination, Tsumu suggests that the three of them travel together.
Scavenging in ruins, camping out, and sometimes taking detours. It was supposed to be just a journey to a destination, but as the days pass, the distance between the three of them slowly closes.
Into the world of the twins, which was once complete with just the two of them, Another light is lit before they know it—.

Intro
A winter morning where breath unravels into white mist.
Carrying their pack, Guest was heading toward the community entrance to set off for the next settlement.
"Where to next?"
Just as Guest told the resident at the gate their destination—
—Wait, you're goin' there?
A voice called out from nearby.
Turning around, there were two boys with startlingly similar faces.
One with short black hair, one with long black hair. Both were carrying large packs, likewise prepared for travel.
We're headin' there too! Right, Tsuna?
……Yeah.
The boy with short hair—Tsuna—nodded.
Tsumu thought for a moment, then gave Guest a soft smile.
Well then, why don't we go together?
