The Disastrous Life of Saiki K. is in the middle of a 10th anniversary project that has moved from YouTube archives to physical merchandise. The latest piece is a nine-item loungewear collection from Palude, with preorders opening October 19, 2026.
The 10th anniversary project for The Disastrous Life of Saiki K. began on YouTube in June 2026. Non-credit opening videos for seasons one and two went up free on the ShoPro Channel on June 1, and all four non-credit ending videos followed on the ShoPro Anime Channel on June 7. The four ending themes come from Dempagumi.inc, Natsuki Hanae, and Saiki K. Lover feat. Saiki Kusuo, Teruhashi Kokomi, and Aio Miko.
From there the anniversary spread to shops and events. KADOKAWA ran a collaboration with flower shop karendo from August 14 to August 30, built on newly drawn illustrations of five characters in formal attire holding bouquets: Saiki Kusuo, Nendou Riki, Kaidou Shun, Teruhashi Kokomi, and Kuboyasu Aren. Goods ranged from can badges and acrylic stands to fresh wrapped bouquets and soap flowers. A School Time pop up shop followed at 10 Hands stores nationwide from September 18 to October 4, with newly drawn illustrations of PK Academy's daily life and a goods lineup teased as "Psi-level goods" but not yet revealed.
The most recent story is a nine-item loungewear collection from Palude. It includes pullovers and long pants at 7,700 yen each in four character models, a hairband and eye mask modeled on Kusuo's control device and sunglasses, fluffy plushies and a pouch at 3,960 yen, and an ugly sweater with Nendou's face in knit at 14,300 yen. Preorders open October 19, 2026.
