What Lies in the Multiverse

• Chapter: 1
• Location: Milleville
• World: Light (as opposed to the Dark one)
• Requirement: sit on the bench alongside the the old lady and wait until her dialogue is over
• Story-related? No; if missed on your first playthrough, you can use chapter select

Upon arriving in Milleville, you'll pass by two wooden houses, a closed store and, finally, reach a big red-leafs tree. Under this tree, an old woman is sitted on a bench.

Go through all the conversation with the old woman and then sit on the bench with her (jump over the bench and then press ). Wait until her story is over. Achievement should pop right away.
