Two massive franchises collide in three minutes of pure comedic chaos, and the show treats this like a genuine story instead of a wink at the camera. A Gundam pilot and Hello Kitty are forced to work together, and the writers commit to their odd-couple dynamic hard enough that you actually care when they bicker. The animation is too good for what is essentially a 15-minute gag, which makes the whole thing land even harder, it refuses to phone in the joke, and that refusal is the joke.

Hello Kitty is getting ready for a tea party when a distress call from Haro reaches her. Answering it, she crosses over into Gundam's Universal Century, aiming to aid Amuro Ray and the Gundam in finishing the One Year War. The three-episode ONA blends mecha action with comedy, and it was produced as a crossover honoring two milestones: four decades of Gundam and forty-five years of Hello Kitty.
