A collaboration between the TV anime "Attack on Titan" based on the original work by Hajime Isayama and Salarist, a sweat prevention innerwear brand developed by Belle Maison, has been announced. A special site has been opened, and Levi's diagnostic content on the level of "sweating people" is being developed.

The Sweat Stain Level Diagnosis
This collaboration project depicts sweat stains that seep into clothing and cause daily stress as giants that threaten humanity. In the ``sweat stain level'' diagnosis conducted on a special site, by answering multiple questions asked by Levi, you will be able to find out your own ``sweat stain level'', and comments and recommended equipment will be suggested according to the results.

Exclusive Merchandise and Giveaway Campaign
Belle Maison Net is also running a giveaway campaign where 100 people will be entered into a lottery to win a diorama acrylic stand by purchasing 4,000 yen or more (tax included) of Saralist products. The figure, background, and base are presented as a set.
Furthermore, on the Chara Maison (tentative) X account developed by Belle Maison, a follow and repost campaign will be held where 100 people will be randomly selected to win a set of 5 characters of "scene trading card & clear card with dialogue". In addition, a pop-up shop will be held at the Metro Opus Umeda store located in front of the north ticket gate of Osaka Metro Umeda Station in Osaka, selling Saraist innerwear, room wear, and "Attack on Titan" goods.

Anyone who purchases over 3,000 yen including tax at the shop will receive one trading card randomly selected from a total of six types. It will end as soon as it runs out.
