The Swords of Mystery. This very strong and ancient site can heal but costs a price that is a mystery. The House of Life use this to bring back all the dead light members but in exchange the Elder One gives his life.
I remember when I couldn't stand One Piece back then because I thought it looked retarded af . Also partly because it was very popular, more popular than my past favorite anime (bleach). I decided to see what was so good about this anime and boiiii I was wrong. I even FORGOT about Bleach. Don't let the art work fool you . Watch this anime ! Its so badass
