If you purchase 『Gintama』 advance tickets before the release date, there are 9 designs that you can choose from: (i) Gintama, Shinpachi and Kagura from 29 Apr; (ii) Kondou, Hijikata and Okita from 20 May; and (iii) Katsura, Otae and Takasugi from 10 Jun.
I was tempted by 4 designs but settled for Suda Masaki’s role of course =D
