What a Friend We Have in Jizōs 8

A month after he killed his cousin Yoshinaka at the Battle of Awazu, Yoshitune defeated the Taira at the Battle of Ichi-no-Tani and, again in 1185, at the Battle of Yashima. But it was on March 24, 1185, at the Battle of Dan-no-ura, during a half-day engagement in the Shimonoseki Strait, that he won the major sea battle of the Genpei War, wiping out the remaining Taira clan to the westernmost of Honshū. 
According to the narrative, the grandmother of the child Emperor Antoku jumped with him into the water.  She turned her face to the young sovereign, holding back her tears.

    ‘Don't you understand? You became an Emperor because you   
     obeyed the Ten Good Precepts in your last life, but now an evil 
     karma holds you fast in its toils. Your good fortune has come to 
     an end. Turn to the east and say goodbye to the Grand Shrine of 
     Ise,  then turn to the west and repeat the sacred name of Amida 
     Buddha, so that he and his host may come to escort you to the 
     Pure Land. This county is a land of sorrow; am taking you to a 
     happy realm called Paradise.’ 

Enter the crab. The Heikigani, Heikeopsis japonica, the Samurai Crab, has a shell that bears a pattern resembling a human face of an angry samurai. Local fishermen believed the crabs are reincarnations of the spirits of the warriors defeated at the Battle of Dan-no-ura, as told in The Tale. Over the intervening centuries, the crab carapaces have, in fact, come to resemble samurai faces more and more. The reason, as first recognized by Julian Huxley in 1952, was that crabs with shells resembling samurai were thrown back to the sea by fishermen out of respect for the Heike warriors, while those not resembling Samurai were eaten, giving the former a greater chance of reproducing. It appears that unnatural selection can also be a voice in the cosmic fugue.
A single Samurai crab in an uncovered bucket will find a way to climb up and out on its own. But if there are others in the bucket, they will fight to pull down the shining striver. And so it was that Yoritomo not only didn’t appreciate Yoshitune’s achievements, he resented them. There is no retraining a Samurai crab to walk straight.
