I have been thinking what has been of koby during the past 2 years, and also of the Ex-Marine officers Sengoku and Garp. Maybe Koby was trained by Garp and Sengoku seeing how the marines need new young strong soliders to keep things running also while koby was in the infirmary the Dr. told him he should ask Garp about his haki.
But now am asking what do you guys think about Garp and Sengoku training koby? PLEASE COMMENT!!!!! ;)
