Present only in Shadow Hearts 2: Covenant Director's Cut. You must have been to the Asuka Stone Platform at least once, and have spoken to the man in the Forest of Wind, for the Sea of Woods to appear on the Japan Map.
Sea of WoodsEdit
Appearing as a maze-like series of floating platforms, the player must activate small shrine-like structures, to create a path through to the centre, and dispel the barrier of Malice protecting the boss.
The Japanese name for the area (樹海, Jukai), is generally used to describe both an area of dense tree-growth, and as a metonym for the forest of Aokigahara. A woods known for its notority as a popular suicide spot, and it's unusual silence (due to the highly clustered nature of the trees).
