How to use = This is the only B Rank Costume in Head Soccer with a special effect. To use it, you don't have to do anything. Every 5 seconds, the Diamond Crown Costume fills around 20% of your Power Bar. The only thing you have to do is to make sure that you wear this Costume as long as possible; so don't let it get kicked off your head, otherwise you can't really take advantage of the Effect of the Costume.
