Another Eden Begins Serial Codes Hub

Serial codes bundled with Another Eden Begins are not Begins codes. You cannot type them into the premium campaign. They are early-bird gifts for Another Eden: The Cat Beyond Time and Space, the long-running mobile and PC gacha. If you only play Begins, you can ignore this hub. If you also play the original, read every platform caveat before 17 September 2026, because the UTC windows are real and the Switch rules are not the same as Steam.

The full game launches 17 September 2026 on Nintendo Switch 2, Nintendo Switch, and Steam. Codes are an early-purchase extra, not a live list of expiring gacha strings inside Begins. For the product difference, see Begins versus the original. For storefronts, see official links.

The three early-bird codes

Official copy lists three gifts.

1. Skip Part 1 “The Cat Beyond Time and Space” story.
This skip is for new players only. On first boot of the original game, choose Skip Part 1; the client then asks for the serial code. It jumps you to events following the main story of Begins, inside the original. Once per person. A used code cannot be entered again.
UTC window: 2026/9/16 15:00 through 2027/9/16 14:59.

2. Item Code Part 1 — Encounter Ramiu ticket x1, plus Begins outfits for Aldo and Feinne.
The ticket runs the “Encounter Ramiu” encounter in the original (5-star Ramiu at 100% on that encounter). Outfits dress the original’s Aldo and Feinne in their Begins looks; they might not appear in certain scenes, and you can only have one of each outfit. Enter from the original’s Menu → Other → Serial Code.
UTC window: 2026/9/16 15:00 through 2027/9/16 14:59.
The encounter itself ends at that timestamp regardless of app version. The ticket’s own use-by is one month from the date received. Extra Ramiu codes grant Light or Shadow; at cap (255) you receive items matched to rank and weapon type.

3. Item Code Part 2 — 5-Star Guaranteed 10 Allies Bundle (Begins) ticket x3.
Each ticket encounters ten characters that were available up to the Begins launch date; the tenth is a guaranteed 5-star or higher. Enter the same Menu → Other → Serial Code path.
UTC window: 2026/9/16 15:00 through 2027/3/15 14:59.
Same “one month from receipt” ticket rule. Duplicate characters upgrade class or add Light/Shadow; at 255 you receive matched items. Published rates for that bundle: encounters 1–9 at ★3 76.3% / ★4 20.4% / ★5 3.3%, encounter 10 at ★5 100%.

You may enter multiple different serial codes. You may not reuse one.

How you actually receive the strings

Steam buyers. Claim via the official Another Eden Begins website. Instructions are listed as forthcoming on that site. Official-site claims remain open until 2027/9/16 14:59 UTC. Steam-claimed codes work on any platform the original game is playable on. They still cannot be used in Begins.

Nintendo Switch and Switch 2 download versions. Serial codes are Japanese version only. Codes from those purchases work on the Android or iOS original. They cannot be used on the PC original, and they cannot be used in Begins.

Physical Japan copies on 17 September 2026 may include the same three early-purchase codes in the box depending on the edition. Western physical copies through Aksys are planned for 2027; do not assume they repeat this early-bird window.

An internet connection is required to receive serial-code items. After an encounter period ends, leftover tickets for that encounter stop working. Items may be reissued later. Questions go to WFS contact at https://www.wfs.games/contact/ — also listed on links.

What this hub will never be

This is not a page of weekly livestream strings for Begins. Begins has no in-game serial-code economy. If a screenshot tells you to enter a code on the Begins title screen, it is describing the original. Keep this hub bookmarked for UTC dates, then spend your actual play time on the demo, combat, and save transfer.

Write the UTC dates on a calendar the day you pre-order. The codes do nothing inside Begins, and they do even less after they expire.
