Eat Sushi to Celebrate Promotion is the 27th episode of the Katekyo Hitman Reborn! anime.
After the defeat of Mukuro, life goes on normally and Tsuna and his friends all move up a grade at school. However, none of them are in the same class, so Reborn offers them a challenge to catch him, with the prize being a change of the roster. Later, they celebrate at a sushi restaurant owned by Yamamoto's father only to find they do not have enough money to pay for their food and have to work off their debt.
- In the manga, Haru wasn't in Yamamoto's father sushi restaurant with Reborn, Bianchi and Lambo, and hence didn't help Tsuna out.
