『 』

『　　』 (kūhaku, "blank") is the online game account shared by Sora (空) and Shiro (白). It became an urban legend in the real world for topping 280+ games without 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』.
