Supplementary Investigation: Off-Duty Gavan Episode 3

Rui takes a can of her favorite cider and fills a cup of it for Setsuna, challenging him to drink it without making a funny face. Setsuna is worried that he'll fail again, because drinking soda causes his facial muscle functions to briefly malfunction. Emorgear Hisor rolls Setsuna a lemon, giving him the idea to reduce the drink's carbonation with the lemon. He then realizes that the lemon's sourness may make the challenge more difficult. He then decides to drink tea before taking on the challenge, but Rui tells him that she drank the last of the tea they had. Setsuna thinks about adding the cider to a helping of Miso soup, but Rui tells him to just drink it. Setsuna drinks the cider, but makes a funny face and falls unconscious twice. Neither he nor Rui notice a humanoid celestial figure writing on the sign they used to write down Setsuna's losses. (Source: Project R.E.D. Wiki)
