Author/Opus: This is the 197th puzzle from our contributing puzzlemaster Grant Fikes.

Rules: Hybrid of Nurikabe and Sashigane, originally created by Grant Fikes. Standard Nurikabe rules are in place for the “ocean” (connected and no 2×2 squares) but the island rules have changed as follows:
1. All islands must be L-shaped and one cell wide. Islands cannot share an edge.
2. An arrow clue points from an end of an island towards the bend in the middle.
3. A circle clue indicates the bend in the middle of an island; if a number is also present, this is the size of the island in cells.
4. An island can have 0, 1, or more of these clues given.
