Nobody talks about this one. Four episodes of two mascot characters stumbling through a sci-fi treasure hunt with the comedic timing of a buddy cop movie, except they're genuinely lovable disasters instead of competent at anything. It wraps itself up completely, leaves you smiling, and respects your time enough to not overstay, the opposite of every other show padding its runtime into numbness.
When a strange stone falls from the sky into Niigata, the city's two beloved mascot characters, Komachi Hanano and Dangorou Sasa, find themselves caught up in an unexpected mystery. The artifact vanishes almost immediately, and nobody can explain where it came from or why it matters. But Komachi and Dangorou aren't about to let the puzzle go unsolved. What begins as a simple search turns into a sprawling adventure across Niigata's familiar landmarks and hidden corners. The pair bickers constantly, crack jokes at each other's expense, and somehow manage to stumble through clues despite their complete lack of detective skills. Along the way, they encounter odd characters, uncover bizarre local secrets, and question whether they're actually equipped to handle whatever cosmic event brought that stone to their city in the first place. This is comedy wrapped around sci-fi speculation: lighthearted fun that treats mascot characters as real people having a genuinely weird day. It's short, silly, and exactly what you'd expect from a quirky local promotional project that refuses to take itself seriously.
