misunderstanding with Giyu

One day, Giyu's friend, whom he rarely saw, dressed up as the second upper moon (Douma), and he was talking to her about missions and work. A raven noticed him (Shinazugawa and Giyu didn't notice him), and this raven told everyone that Tomioka the Water Pillar was reporting to a demon (the raven didn't realize it was a person dressed up as this demon), who was closest to their main enemy, Kibutsuji Muzan, about missions and patrols.
