Dr. Stone: Ryusui

Having rebuilt civilization from scratch using nothing but science and sheer stubbornness, Senku Ishigami now needs a boat. Specifically, he needs to cross an entire ocean to figure out why humanity got turned to stone thousands of years ago. The Kingdom of Science has the manpower and the know-how to build the ship, but they're missing one crucial thing, someone who actually knows how to sail it. Enter Ryusui Nanami, a petrified heir to a shipping empire who's equal parts brilliant navigator and shameless egomaniac. This TV special from TMS Entertainment covers the revival of Ryusui and the chaos that follows when you add a guy with zero humility and unlimited ambition to a group that already has plenty of strong personalities. The comedic chemistry between Ryusui and the rest of the crew is genuinely fun, and the show keeps doing what Dr. Stone does best: turning real-world science into surprisingly engaging problem-solving. It's one episode, so it's a quick watch that bridges the gap between seasons while setting up the ocean voyage arc. If you liked the strategic cat-and-mouse tension of The Promised Neverland or the way Steins;Gate makes science feel personal and high-stakes, Dr. Stone scratches a similar itch but with a lighter, more adventurous tone. Worth your time if you're already invested, and a good taste test if you're curious about the series.
