『 』

『　　』 (kūhaku, "blank") is the online game account shared by Sora (空) and Shiro (白). It became an urban legend in the real world for holding the top score of over 280 games without having any recorded losses. After Sora and Shiro were called to Disboard by Tet, they used the name to refer to themselves.

『　　』 is generally depicted by four game accounts, the main account being named 『　　』, and the others named 『　SUB01』, 『　SUB02』, and 『　SUB03』.
