You need to buy it.

But first you have to buy Toriprime then you buy theV.I.P

how much VIP per month to pay

AoZ, How bout you check out the page? -.-

If you have much tc (app. 500k), I heard you can request it from crux.
But rl money payment is good way either.

To be able to buy VIP, you have to buy toriprime first.

Toriprime is $10.00 for a full year.
If you would like to add on VIP to your toriprime, that would cost you an extra $7.00 every six months, or $14.00 a year.
