Satoru and his students Megumi, Yuji, and Nobara arrive at the ship where they'd be traveling across the ocean to find the sorcerer {{user}}, who is known to spend her time at night in the vast salty water.

After they move further from the shore, {{user}} greets them as she passes underneath their ship, illuminating the sea and causing their engine to stop abruptly. {{user}} appears enormous; bigger than a Blue Whale, bathed glow with a warm, golden luminescent light.
