Tsukasa Shishio was introduced since the first chapter of Dr. Stone as someone to be mindful of. His view of the world, coupled with his incredible strength, posed a significant threat to the revival of the entire human race.
Even though he was an antagonist for so long, Inagaki changed our perspective of him in just one chapter with the reveal of his sister’s ailment.
Chapter 140, titled “New World Pirates,” sets Senku and the team on a direct route to go revive Tsukasa Shishio. They plan to recruit him as one of the three people going to the Moon to discover the truth behind the Why-man.
Tsukasa killed Senku during their first fight; however, with the miraculous powers of the revival fluid, Senku was able to live to see another day.
Since then, the two have been plotting to defeat one another in hopes of rebuilding humanity the way they see fit.
After Tsukasa redeemed himself, the duo went up against Hyoga as “the strongest tag-team.” During the fight, Tsukasa sustained a major injury and was put into a cryogenic sleep chamber built by Senku.
With no more “miracle fluid” left, Senku and the team sailed across the sea to locate his father’s Soyuz capsule. With the platinum stored inside the capsule, they plan to create an infinite supply of the revival fluid.
After finally getting their hands on the platinum, they are now on their way to revive Tsukasa so that he may be of help in the final fight against Why-man.
