The maze-like interior of the “Seiraimaru” boat is home to a plethora of puzzles, including a Relay Stone puzzle that involves three Relay Stones and a lot of Electro lines. To access this puzzle, you first need to complete theMemory Tile puzzlesthat start at the entrance of the boat.
After the two Memory Tile puzzles are done, a hole in the ship’s wall will open (on the same floor as the second puzzle), leading to a large expanse that houses the Relay Stone puzzle.
The first thing you’ll find is a shipwreck with a Phase Gate and an inactive Thunder Sakura Bough. Use the Phase Gate to traverse the area—make sure it’s facing the direction you want to travel to. Your goal is to obtainthree Relay Stonesand place them in the same locations as prescribed in the images below.

The leftmost Stone should be on top of a protruding plank at the edge of the ship. See the below image for a clearer reference of its location.
It’s important that all the Relay, Cumulation, and Discharge Stones are connected to each other by the Electro lines. If they are not, then make micro-adjustments to the Relay Stones' positions until they’re all connected.

Look straight ahead from the Phase Gate on the shipwreck and turn on Elemental Sight. You’ll find a breakable Electro Rock Pile beside a Thunder Sakura Bough. Approach it, and break the Rock Pile to reveal another Phase Gate and a Relay Stone.
