USK (sometimes written as USK, with the Greek kappa letter substituted for the K) is a Touhou player mainly specializing in Easy and Normal modes of Mountain of Faith. He is famous for optimizing some of the Easy mode replays to such extent where, as he has put it, "further improvement depends on luck from this point on".
