Atlus opened a teaser site with a picture of a giant tree and a humorous title that reads, "This is not broccoli #ATLUS." The page has gigantic tree, Atlus (written in katakana), broccoli (written in katakana), broccoli, and Atlus as keywords.

We also found these images linked on the teaser site.

Here’s how the whole tree looks:

The tree and font are awfully reminiscent of the Etrian Odyssey series so we’re betting on an announcement for Atlus’ dungeon crawler series in the near future.
