It seems like the Love Live! girls continue to find themselves in new promotions for Lawson. The convenience store chain announced a new campaign that kicks off next month. Unlike the most recent efforts, though, this one appears to focus primarily on bashful beauty Umi Sonoda.

Sonoda was chosen by customers to be the official Lawson Image Girl in a previous campaign. To celebrate the upcoming event, Lawson released a visual of Sonoda decked out in a Lawson uniform.

The promotion itself will primarily be a stamp collection campaign. Customers who buy specially marked rice balls, as well as those who buy 9 items or more, will receive a stamp, which can be used to exchange for limited-edition goods. In addition, the company will give away promotional tickets that offer customers a chance to purchase special-edition items starting on December 16th.

The prizes on offer include cell phone straps, ramen sets, name plates, a signed tapestry, and a μ’s Christmas poster.
