Mostkawaii

When I created my account, I didn't know that this nickname would be the same in game and I made the account in a hurry. I just want to change the "k" to "K" (Mostkawaii for MostKawaii), but that costs 25 euros and is VERY expensive for someone living in Brazil . I was wondering if it is possible to make this change or delete my account so I can create it again? Edit: My English is bad so I'm using a translator :v
