Write a poem about a liminal or transitional space in Haikyuu!!.
“Liminal” refers to a place or sensation that exists at or on both sides of a boundary or threshold, neither one thing nor the other, but something in between.
You could write about any place that feels like a point between origin and destination: a bus, a convenience store, an intersection, or anything depending on your interpretation – from the perspective of the characters, or even the place itself.
If you need more structure: write about the liminal space that is the mid-timeskip period, for a character or ship (or even place!) of your choice.
