:

While figuring out the truth about her brother's disappearance, Shiro remembers that Sora is having a high-stakes game of Othello with Clammy in which they are betting their own existence and memories. With Sora in a dire position and unable to continue the game, Shiro assumes his place according to the game's rules and wins. With this, the siblings not only earn Clammy's allegiance and the support of her Elf partner, Feel Nilvalen, but by sharing his memories with her, Sora finally wins her trust.
