Hello, World (HELLO (ハロー) WORLD (ワールド) Harō Wārudo) is the two hundred and sixteenth chapter of the Dr. Stone manga.


The chapter begins with another rocket exploding, and Chrome discussing how difficult it is to get a rocket into space with Suika. The pair continue observing their mentors' work, while working on their own return rocket design and learning from the mistakes made with each failed rocket.

Eventually, a rocket makes it into space and successfully gets a recon satellite into orbit on their 7th attempt. With a rocket in space, Chrome faces the fact that the rocket he's building with Suika needs to be at least five times bigger than the one that got sent up.

The first images from space get beamed down to Earth, allowing Chelsea and Ryusui to begin globetrotting once more to revive the rest of humanity, using a more accurate map. A new revised globe is shown, and several new boats and cities have been built around the world. Soon, a space telescope is also sent into orbit.

With the new view of the moon's surface, Kohaku begins scanning the images. Xeno is skeptical, but Senku points out that Kohaku's eyesight is based off her high focus and attention to detail. Outside, Chrome and Suika establish their rocket's deadline: the moment Kohaku locates Why-man. When that happens, Senku will want to speed off into space as soon as possible.

More time passes, until one day Kohaku finds an odd black blob on one of the images that changes over time. Xeno confirms that it's not a normal lunar phenomenon, and thus Why-man is located.
