After leaving the pirate ship, Shard felt hunger, but his physical and spiritual energy had normalized within minutes. However, even with a fourth wish and the healing at the end of the Maze Lock, Miss Princess took longer to recover, and after swimming continuously for so long, the sorceress from the Five Rings looked strong but was actually near her limit.
The people on the small boat promptly noticed the floating plank and the two people swimming toward them, and they quickly converged.
The maid on the boat reached out to pull Miss Princess aboard, but the sorceress was too exhausted, so Shard had to support her into the boat first before he could clamber aboard himself.
