Have Fun! It's the End of the World!(2020)

Sekai wa Owattemo Ikirutte Tanoshii

In a world nearing its end, little Yakone wanders a dying planet alongside Yago, her hamster-like companion, and Ney, a loyal drone. As they traverse landscapes shrouded by a mysterious red mist that warps nature itself, they uncover pockets of joy -–like delicious meals, crumbling ruins, and quiet companionship. Adventure blossoms in the most unlikely places, painting a hopeful portrait against a backdrop of decay.
