King of the Stone World
Senku and Taiju prepare enough revival fluid to free one person from stone, with Taiju choosing Yuzuriha to be first subject. However, they are suddenly chased by hungry lions so instead they revive Tsukasa Shishio, the strongest fighter in their school. He beats off the lions and also proves to be a valuable hunter, providing food for the trio. Senku assigns Taiju to harvest seashells and grind them into calcium carbonate as a first step towards advancing civilization. However, after Tsukasa smashes the stone body of a man who assaulted him as a child, he states that he is against reviving the corrupt adults of human society, clashing with Senku's ideals of reviving everyone.
