Kairyuu to Yuubinyasan

Hana, a 12-year-old girl in the Paldea region, wants to grow up to be a mail carrier — specifically because she idolizes Dragonite, the Pokémon famous for delivering letters. One day she finds a letter with no address on it, and instead of tossing it aside, she drags her partner Fuecoco across town trying to track down whoever wrote it. Turns out it's a kid named Rio who wanted to send a birthday letter to his dad, stationed far away in the Kanto region. What follows is a short, warm story about making sure the right words reach the right person in time. This is a single ONA episode produced by CoMix Wave Films — yeah, the studio behind Your Name and Weathering With You — so the visuals are genuinely gorgeous in a way Pokémon content rarely gets to be. The theme song is by suis from Yorushika, which sets the tone perfectly. If you liked Pokémon: Twilight Wings or Pokémon: Hisuian Snow, this fits right alongside those as a standalone story that uses the Pokémon world to tell something quieter and more personal than the main series ever does. It's not about battles or catching them all. It's about a girl, a letter, and the small but meaningful work of connecting people. The kind of thing that sneaks up on you emotionally even though it's aimed at kids.
