A stamp rally in collaboration with "Kaiju Decode" was held at the 52nd Sakai Festival on October 19, 2025. As a prize, a limited edition T-shirt (20 pieces only) provided by Toei Animation was awarded, but I am selling it as I will not be using it. Brand new, unopened. Size: L (as it is unopened, I have not taken measurements) As a bonus, I am also including the completed stamp rally card. The new anime "Kaiju Decode: Aida's Ring" is set in Sakai City. This is an original CG animation jointly produced by Tsuburaya Productions Co., Ltd. and Toei Animation Co., Ltd., with the theme of "a story of kaiju and a girl." The story follows Mar, a boy living peacefully in the city, a society free from the constraints of body, mind, space, and time, and Coco, a girl from the Aida tribe living in the dangerous land: the Zone, where super-dimensional beings reside. The story explores how these two, from opposing positions, seek a way to live together. Color: Black系 Pattern/Design: Print (logo, etc.) Stains, tears, odors, etc.: None
