One collection, 36 artworks.
Each collection contains 24 Originals, 8 Rare, 3 Art and 1 Signature. Every card has its own illustration and story, with no alternate versions to collect.
Original cards have a paper frame; Rare cards catch the light in bronze, Art in silver and Signature in gold. Explore the four finishes.
Each collection page shows three Originals. The home page also presents real Rare, Art and Signature cards from its featured collection, plus a fixed five-card Hokkaido sample ending with a Rare card. Selected illustrations introduce each world. Viewing a preview never adds cards to your album.
Your free discovery pack.
Open five selected Tokyo After Rain cards before signing in: four Originals and one Rare. Confirm your email to keep these same five cards in your account. This fixed selection is a separate offer from randomly drawn boosters; the 70/25/5 rarity odds do not apply to it.
There is one discovery gift per account. It counts as one pack toward the collection’s twenty-pack completion guarantee. Finish any pending Tokyo opening or checkout before claiming it. If your Tokyo collection is already complete, you already have these five cards.
Your discovery pack is separate from Omikuji: all five daily stamps and the Omikuji booster remain available under their usual rules.
Open my discovery pack ↗What is inside a booster?
Five different cards from one collection: four Originals and one rarity slot. The fifth card has a 70% chance of being Rare, 25% Art and 5% Signature. These odds apply to the rarity category, not each individual card.
While you are missing Originals, the first card is chosen equally from those missing. The next three are selected equally from all remaining Originals in that pack. Within the fifth card’s drawn rarity, missing cards are chosen first with equal chances. Once that rarity is complete, any card in it can appear again.
Repeats are possible between boosters. A repeat does not fill another album space.
A collection you can finish.
Your twentieth booster in each collection includes any artworks you still need as a completion bonus, added after you reveal its five cards. Each collection counts separately. You can finish earlier through the ordinary draws.
No deadlines or streaks to maintain. Your next card will wait for you.
Open it. Make it yours.
Slide across the wrapper or choose “Tear open”. Swipe left, tap a card or press “Next card” to continue. Go back, reveal all five, or close and resume later. Sound is optional; reduced-motion preferences are respected.
Your album counts revealed, unique cards by collection and world. Open a collected card to read its story and choose up to three favorites per collection.
After revealing all five cards, “Share my five” prepares an image to download or share. Nothing is posted automatically, and account details are never included.
A little daily ritual.
Draw your Omikuji for an original Rainfolio thought and one stamp per day, saved to your account. A new day begins at midnight in Japan (JST). Your fortune stays the same that day, even after a refresh. Your stamps never reset when you miss a visit.
Your first five different days unlock one free five-card welcome booster per account. Choose any available, unfinished collection. The gift stays available until used; finish any pending opening or checkout in your chosen collection first. Daily fortunes continue after that first gift, without additional booster rewards.
The free booster follows the same rarity odds, duplicate rules and twentieth-booster completion guarantee as purchased boosters, and counts toward that collection’s total. The fortune’s luck level never changes your card probabilities.
About your purchase.
Purchased boosters cost €1.49. All saved boosters, including the Omikuji welcome gift, require an account. Sign in by email to save your five digital cards across devices. Resuming or revisiting a paid opening is free, including after a refresh or interruption.
Digital collectibles only: no physical delivery, cash value, trading or resale. Rarity never awards a monetary prize. The home-page sample adds nothing to your album. Older browser demos stay on their original device and do not transfer to an account.
