"Dr. Stone" Chapter 205 will explore the ability of Ryusui's math genius brother Sai Nanami. As some say that the professor has a brain that works a million times faster than the average person, can he help Senku pull off interplanetary calculations?

 Sai Nanami is not an ordinary math professor. With that, Senku needs his help to make calculations correct up to 15th place of decimal in "Dr. Stone" Chapter 205.

According to Epic Dope, Ryusui is very confident of his brother's ability, so he will surely live up to expectations. Therefore, the exploration team may continue to stay in India for a couple of days to fully enjoy their trip, just like they did when they were in Spain.

So, Senku may revive more people in India. This way, they can establish a new base in the country.

If not, they may go straight ahead to Japan to revive Ruri and others. With their moon mission, Senku needs as many people as he can get and can only do it by traveling the world further eastward.

In addition, fans may see Kaseki and Joel's reunion in Corn City in "Dr. Stone" Chapter 205. This get-together may even result in discovering a few more secrets about the medusa device.

In "Dr. Stone" Chapter 204, Kohaku had no idea why they were heading to India. She knew that it was called Math City but still did not know the meaning behind it, OtakuKart News noted.

Ryusui then quoted Galileo Galilei, who said the "universe was written in the language of mathematics." Senku just enjoyed watching Ryusui controlling the boat, while Ryui said they were looking for a universal language.

Chrome added what Ryui said sounded fantastic and Kohaku got excited about it, though she knew nothing about it. Ryusui then talked about how he guided the missile manually and said things about the trajectory.

Gen believed things would be difficult for Senku to calculate. The science genius then realized Ryusui's plan would not work for the rocket if their number were one digit short.

The rocket would not operate and might only explode in the air - resulting in everybody's death. The group then talked about NASA and Chelsea said they had to make the correct calculations.

From here, Ryusui realized it was hard to defeat India when it comes to its education - knowing its people could memorize the times table up to the double-digit.

"Dr. Stone" Chapter 205 will be released Sunday on Viz Media and Shueisha's Manga.
