Grand Fortune Wishing Wall[edit]
From 2026/01/16 to 2026/01/30, the player will be able to pick two out of ten Wishing Walls every day, which gives 
Orundum with the highest among the picked Wishing Wall being the reward (e.g. if the first Wishing Wall gives 400 
and the second gives 800 , then the player will receive the latter).
- The possible Orundum values in each Wishing Wall are 200, 300, 400, 500, 600, and 800.
- If the player receives less than 400 from the Wishing Wall, they will be able to pick a third Wishing Wall in the next day.
- All unused Wishing Wall picks do not stack, so they must be used before the daily reset.
Trivia[edit]
- The title has four-fold meanings. Ato (あと) in Japanese usually means "after; behind" (後) or "trace" (跡; as in "footprint " ashiato
足跡 ). It could occasionally mean "scar" in on-yomi (痕). Hence, the event's name has the symbolism of "leaving behind the scarred traces of ruins." - Ato features easter eggs from Japanese modern culture:
- In the zone images of District of Eternal Neon between AT-ST-2 and AT-6, two popular Internet memes appear. The lefthand side features three girls referencing a 2024 meme based on a Google Street View captured image featuring three female highschoolers striking a hilarious pose. The bottom right features three salarymen heading towards an underground passageway referencing the 2023 Japanese horror game The Exit 8.
- The zone image also features a graphic design bearing resemblance to three of the transit lines of the Toei Subway: the Asakusa Line, the Mita Line, and the Shinjuku Line.
- Between AT-1 and AT-2, there exists a convenience store whose color scheme resembles to that of FamilyMart. The zebra crossing is inspired by that of the Shibuya Crossing.
- With only a single word of 3 characters, Ato currently holds the record for the shortest event name.
Notes[edit]
- ↑ Cantonese for cold drinking house, a type of traditional restaurant popular in Guangzhou and Hong Kong area
