The Disastrous Life of Saiki K. is in its 10th anniversary period, marked by free releases of non-credit opening and ending videos on YouTube and a collaboration with flower shop karendo running from August 14 to August 30, 2026.
The Disastrous Life of Saiki K. is in the middle of a 10th anniversary project that has moved from digital archives to physical retail. In June 2026, the non-credit opening videos for seasons one and two were released for free on the ShoPro Channel YouTube channel, followed a week later by all four non-credit ending videos. The endings cover both seasons, with first season songs by Dempagumi.inc and Natsuki Hanae, and second season songs by Dempagumi.inc and Saiki K. Lover feat. Saiki Kusuo, Teruhashi Kokomi, and Aio Miko.
The anniversary push then turned to merchandise and in-person events. KADOKAWA announced a collaboration with flower shop karendo running from August 14 to August 30, 2026, under the theme of flowers. The key visual shows five characters in formal attire holding bouquets: Saiki Kusuo, Nendou Riki, Kaidou Shun, Teruhashi Kokomi, and Kuboyasu Aren. Original goods use newly drawn illustrations, and flower products range from fresh wrapped bouquets to soap flowers in LED rainbow bouquets, glass domes, and cake-style arrangements.
The collaboration includes purchase bonuses: a random illustration card for every 2,200 yen spent on eligible products, and a mini character sticker with each flower product purchase. Six stores display large panels of different characters, while 13 stores sell only flower products. Online orders run from August 14 to August 30, with delivery around December 2026. A special site is open for the collaboration.
