To win a D4FES commemorative skin you need to go to this site:

https://d4djcampaign.bushimo.jp/gacha2/top

-Click the big violet button below the "?" sign.

-You will get a random skin and you have to decide if you want to keep or not.

-If you don't want it, click the Big button again. You have a total of 5 tries.

-When you try again and have more than 2 skins to choose, you select the one you want the most by clicking it, and when you try again only the one YOU DIDN'T SELECT will change to other random skin. You always keep the one that is selected (the one with the yellow box on it)

-Once you got what you want, scroll down and click on the second big violet button. It will generate a serial number that you need to copy and save (if you click the yellow button it will auto-copy the serial for you).

-Click on the violet button or go to this site:

https://serial-code.d4dj-groovy-mix.com/

-First input-box: is for your PLAYER ID

-Second input-box: is for the serial code

-Click the Blue Button ("send") and that's it. You'll get the skin on your inbox

(I didn't claim that skin, so I think the first to do it can keep it. If you do please comment here.)
