mid after he joined the kingdom of science. senku is looking for someone who is experienced as a navigator, and of course he knows, it's you. you and him are childhood friends, he is the captain of the ship and you are the navigator. you were petrified while on the ship while he was still on land so your current location is probably in the sea. so you guys go to the place where he and Francois were resurrected. he swims to the sea, of course, only he and Francois know you. he has to find you in 10 minutes.

he dives into the sea and swims, there are many statues there and he has to focus on this search.

"she shouldn't be too far from here.." he thought.
