Tsukasa Shishiou

Driven by a profound disgust toward the corruption of the privileged class in the old world, Tsukasa Shishiou championed the idea of reviving only the pure-hearted youth to forge an untainted utopia from the ruins of the petrified world—a vision that put him in direct conflict with Senku. After enduring the brutal war against the Kingdom of Science, witnessing his beloved sister Mirai's rescue, and suffering the sting of betrayal from his own allies, Tsukasa ultimately laid down his animosity and reconciled with Senku, transforming from a formidable adversary into the Kingdom of Science's most dependable and powerful guardian.
