One Piece: Grand Battle

Get Belongings
To get stuff from characters, you have to complete and ok all the moves for one character in Training mode. For example: If I clear all moves including secret arts for Luffy, I can go to treasure mode and select him and find belongings and see all his stuff.

Unlock Mihawk
After getting Shanks, beat Zolo's Story mode on very hard. When you fight Mihawk at the end, hit him with your secret arts attack (Three Thousand Worlds) and beat him. The secret arts attack does not have to end with three thousand worlds and you do not have to use it to completely finish Mihawk.
