Bikkuriman

Bikkuriman is a chocolate and peanut wafer snack made by Lotte that sold for 30 yen at the time of its introduction. Originally, the pack-in stickers were called “Dokkiri Seal” (どっきりシール, “Shocking Seal). Each Seal featured a realistic image on a clear background, with the intention of using them for pranks or gags (broken glass, clothing tears, fake wall switches, etc.) By the 1980s, the Seals began featuring individual gag-based characters with a theme that united a particular set of Seals. These style of stickers would remain for the first 9 sets of Seal releases.

In August 1985, Lotte released the first of the Akuma vs Tenshi Seal series. While maintaining the same humorous art style of the earlier series, the Akuma vs Tenshi Seals featured characters based on assorted mythological, folklore, and even metaphorical sources engaging in an overarching story-line. Akin to the Mars Attacks trading card series from America, the battle between the Tenshi and Akuma is told on the back of each sticker, with the plot progressing with each new set. Each set was divided into several themed tiers featuring a Tenshi, Akuma, and an Omamori (お守り, "Protector"), with an ultra-rare "Head" Seal that serves as the main character of its particular set. The Head Seals were typically printed with a prism or holographic holofoil to set them apart from the Tenshi's metallic silver or gold backing, the clear backgrounds of the Omamori and the multi-colored backgrounds of the Akuma. The rarity of the early Akuma vs Tenshi Seals were, in order: Head, Tenshi, Omamori, Akuma.

Unfortunately, the popularity of the stickers led to trouble for the series. The zeal to try to obtain Head Seals would lead children to buy Bikkuriman in mass quantities, retrieve the stickers inside, and simply throw away the snack. This, along with the fact that children and collectors were willing to pay high amounts of money for the rarer cards, led to parent groups expressing concern of possible gambling implications for the stickers. This led to action by the Japanese Fair Trade Commission, and the number of Head Seals per pack was increased from the average 4 to 24 individual Seals.

These stickers were a huge success, leading to a multitude of media tie-ins. The original Bikkuriman anime series, created by Toei Animation, aired from October 11, 1987, to April 2, 1989.[1] Sequels include Shin Bikkuriman, Super Bikkuriman, Bikkuriman 2000 and Happy Lucky Bikkuriman.
