The Aloha shirt worn by Son Goku in the Goku Day campaign was distributed as a costume for the main character, Charlotte. The distributed Aloha shirt has a cover of 22 volumes
It seems that it will be the Aloha shirt worn at the time of the Air Car Driving School with Piccolo in 125 episodes of Dragon Ball Z "Licensed everyone? New trial of Goku".

The back view looks like this. A great gift for Goku fans.
