As far as I know, there isn't any ID-checking on regular tickets, since those are going into the sales for non-dears members after this.

I have ordered tons of tickets for friends who are going with me or others or a group we're in, and my friendly person told me it wasn't a problem to buy regulars for non-dears members.
After all, they are meant for bringing your friends. So have fun at Gackt's coming tour! I might even spot you without knowing, lol XD
