== Tradition ==
Maruko began a tradition usually performed by the Kaito Shrine-Keepers, to climb the peak of Garanto Mountain, to reach the snow-swept summit to meditate for three days. After such period, they fired a single arrow, which would go to wherever that shrine keeper's destinity lies. The keeper sought the arrow until they found where it landed. This tradition rose a superstition among the Garanto peasants, and they left untouched any arrow sticking up form the ground, to pluck it from the earth would be to invite a terrible calamity.
