A person who was abandoned by the world, because of a strange combination of circumstances, traveled to Hokage and became a member of the Uchiha family. God said to accept the judgment of fate. After that, he entered the Soul Society on his own and lost all his memory as punishment for disturbing the order. Just the instinct to fight. Adopted by Shiba Haiyan.
Being abandoned by the world, knowing that everyone has forgotten you, even if you don't want to...
I once vowed not to be abandoned by the world. Then maybe just abandon it before it abandons you.
However, is this really possible?
