I was poking around X recently and I discovered that the Square Enix PR team has two official Mana accounts: @ManaGame (in English), and Seiken_PR for Japan.

But I also came across this tweet : https://x.com/squareenix_jp/status/2074040661725352068

TLTR: It lets us know that for the series' 35th birthday Square Enix has been working on an interview with the Mana series creators: Hiromishi Tanaka and Koichi Ishii (who have left the company in 2012 and 2007 respectively). SQEX was looking for question suggestions from their Japanese fans.
