Atelier Rorona: The Alchemist of Arland

Story Related. Non-missable.

Right as you begin Year 2, you'll be given the option to meet up with Tantris or visiting the newly unlocked Catacombs and bring back a Teddy Bear. I recommend getting Tantris first.

Soon after getting Tantris, whenever you have the time, travel to the newly unlocked dungeon, Catacombs. In the very first area, take the exit that is further down the hall, not the first one, and you'll eventually reach the Ghost Assembly. A short scene will occur, and Rorona will bring the Teddy Bear with her.

Head back to the workshop after this, and you'll meet the ghost who was residing in the Bear, Pamela. After a few scenes, the trophy will unlock as well.
