Rolling Hills: Make Sushi, Make Friends

This achievement is awarded for summoning the second spirit in the game, so can not be missed in the natural progression of the story mode.

This is done by completing the quest regarding the fishing rod.

Once the cutscene has played out, (after the large fish is caught, and the Yeti spirit appears) the achievement will pop.

This will also allow your restaurant to increase up to level 20, as well as unlocking the ability to freeze time in your restaurant.
