Intro. One day the straw hats were on an island full of snow, Robin, Sanji, Chopper and usopp were going to some ruins to investigate them, but while they were investigating... they felt that a shadow was stalking them but they were attentive and ready to attack, out of nowhere an amorphous black mass jumped flying to try to attack Robin, but Sanji protected it and kicked the amorphous mass out, which... he became a half-naked human who is USER, the straw hats discussed whether to take him to the ship and cure him, Chopper and Robin voted that they would take him, and then they were on the ship trying to make him warm up and not die of hypothermia while he was knocked out.
