The Japanese Red Cross Society is known for using anime, manga, and light novels to promote its blood donation campaigns, including previous crossovers with the likes of Uzaki-chan Wants to Hang Out!. Now another promotion is kicking off with the help of Shirow Shiratori’s The Ryuo’s Work is Never Done! light novel series.
Those who donate 400ml of blood or take part in the apheresis donation at Tokyo’s various blood donation locations between July 1 and August 16 will receive a special clear file as a bonus. You can see the illustration—which combines Shirabii’s limited and standard edition covers of the novel’s seventh volume—below.
The Ryuo’s Work is Never Done! was previously adapted into a 12-episode TV anime in 2018.
