The Asian/ Hong Kong first edition was released in Taiwan with an age ratings sticker on the front and a sticker from the distributor on the back. At some point reprints got updated stickers from the distributor. The insert is dual-sided with English and Japanese titles.
1. Front (Japanese title)
2. Back (Japanese title, old Justdan sticker)
3. Front (English title)
4. Back (English title, new Justdan sticker)
