Tsukasa Shishio
The warrior who killed a lion with one punch to protect his sister's memory.
Tsukasa Shishio is a youth who rose to fame in mixed martial arts as 'The Strongest Primate High Schooler,' physically powerful enough to kill a lion with one punch. After being reawakened by Senku to save him and Taiju from a lion pack, Tsukasa wears the pelt of the male lion he killed. He resents adults due to a doctor refusing to treat his comatose sister Mirai, who was already brain-dead and beyond help, leading him to view current adults as corrupt while seeking to create a new society by only reviving young people. Initially serving as the primary antagonist who establishes the 'Empire of Might,' he later accepts a truce with Senku in exchange for the theoretical revival of his sister. After suffering critical injuries and being placed in cryosleep, the Empire of Might effectively dissolved, and the Kingdom of Science absorbed some of his followers. Upon revival, he sides with Senku on their trip to the United States of America.

Lore & Background
Tsukasa was revived by Senku shortly after awakening in the Stone World. He founded the Empire of Might based on the philosophy that only young people should be revived, rejecting adults he views as avariciously corrupt. His conflict with Senku ended when he accepted a truce to potentially revive his sister Mirai. Following betrayal by Hyoga and critical injuries sustained in battle, Tsukasa entered cryosleep before his sister's revival was confirmed. He only learned of her recovery later. When revived, he joined Senku's expedition to the United States of America.
In Their Own Story
In the Stone World, Tsukasa kills a lion with a single punch and wears its pelt. He leads the Empire of Might against Senku's Kingdom of Science until Hyoga betrays him during a truce negotiation. Severely injured in the subsequent fight, he is placed in cryosleep while his sister Mirai is healed. Years later, after being revived from stasis, he accompanies Senku on a voyage to America.
