During a stream featuring Yuu Kamiya and Nana Momorio, Kamiya decides to show one of the artworks featured in the upcoming Art Book. In this shot, we have Sora with Shiro in his arm while the other holding 3 chess pieces. The full version of the artwork will include Jibril, Steph, and Chlammy, which are to the right of Sora and Shiro.
During the same stream, Kamiya pulls up an artwork featuring Sora. He jokes around by pointing the camera towards Sora's v-line, Nana giggles in response to this.
