This show tells you it's a cozy girls-on-a-train comedy, then systematically destroys that assumption every three episodes. The humor works because it's rooted in genuine character moments, the girls actually care about finding their friend, which makes the increasingly surreal and horrifying stops along the way land harder than pure absurdism ever could. It's a show that knows when to be funny and when to be quietly devastating, and it refuses to pick a lane even though that should make it fall apart. The pacing suffers from fitting 24 episodes of ideas into 12, but what made it through is strange enough that you'll keep thinking about specific scenes weeks later.
Four girls climb aboard an abandoned train leaving their isolated town with one mission: rescue a missing friend. Shizuru refuses to accept that her closest companion has simply vanished, so she convinces three others to join her on a journey into the world beyond their remote village, a place they've never been allowed to explore. The catch is nobody knows what lies outside their hometown. The train itself feels wrong, moving through landscapes that shift between familiar and utterly alien. Reality warps around them as they travel deeper into unknown territory, encountering increasingly bizarre phenomena that suggest something far larger than a missing person case is unfolding. Equal parts mystery and absurdist comedy, the show balances genuine stakes with moments of everyday friendship chaos. The girls bicker, laugh, and support each other while wrestling with the possibility that leaving home might mean they can never return. Every stop brings new questions about what happened to their friend and what's actually going on in the world outside their small town. The final destination remains uncertain until the very end.
