Faith in the third-day moon

A 16th century warrior, Yamanaka Shikanosuke Yukimori (1545-1578) is said to have taken his first head at age 13. He served the lord of Izumo province, and fought many battles against the Mōri, an invading clan. Among Yukimori's many exploits was a single combat against a Mōri champion on a small island, surrounded by forces from both sides. He believed in the luck of the 'mikazuki' or third-day moon, and he wears this moon upon his helmet. Yukimori died at the age of 34.
