NIJISANJI's official Japanese X account (@nijisanji_app) announced on September 13, 2026 (Japan time) that a solo birthday project for affiliated Liver Shioriha Ruri (Ruri Shioriha, X: @Ruri_4ori8), titled "Shioriha Ruri Birthday Goods & Voice 2026," will be released. This is a new announcement specifically for Shioriha Ruri, separate from the birthday sets for Kokonami Iruka and Ryoma Barrenwort. According to the official post, sales will begin at 18:00 JST on Sunday, September 20, 2026. The sales channel is stated as the NIJISANJI Official Store (shop.nijisanji.jp). The wording "sales decided" indicates this is a pre-announcement, with orders not yet open as of September 13. The post does not disclose the product lineup, set contents, prices, or order deadline. Past birthday goods & voice sets have typically combined items such as acrylic panels, badges, cheki-style cards, a birthday voice track and bonus wallpaper, but the 2026 lineup for Shioriha Ruri must be confirmed on the official store product page and in future official updates. Fans are expected to be able to purchase from the Shioriha Ruri page on the NIJISANJI Official Store after 18:00 on September 20. Sales period and purchase limits will follow the store page.
