Sleepless
Kinka (金華) and Ginka (銀華)

A team seen briefly in volume 2. Ginka (the woman) and Kinka (the man) are pretty minor characters, and aren't given very much dialogue or personality. After losing a fight with Soubi and Ritsuka, Sleepless have a nasty encounter with the boy Zeros, of which the outcome is not shown.

The location of their markings is unknown.
