Dr. Stone (
Mirai tries sneaking into the cave where the injured Tsukasa is being kept, but is quickly caught by Yuzuriha delivering supplies. Senku asks for her help with sewing Tsukasa up, which causes Mirai to faint. Later, Kohaku tells Mirai that Senku will find a way for her brother to come back, and that she shouldn't worry.
Back in the cave, Tsukasa and Senku discuss options. The Stone World isn't a safe place for surgery, and Tsukasa claims he'd die of sepsis in days. Senku offers the option of "petrifying" Tsukasa again by cryogenically freezing him, killing him and preserving his body so Senku has the time to solve the petrification before Tsukasa dies properly.
Kaseki begins working on building a refrigerator for storing Tsukasa, powered by one of the waterfalls in Roppongi. Once it's completed, Kaseki shoos everyone out so Senku and Tsukasa can have a private final conversation.
Senku makes small talk with Tsukasa, asking him who he'd bring to space and the like. Eventually, while Senku is talking, Tsukasa stops responding.
Mirai is then let in to the refrigerator room, and vows to keep an eye on her brother as he'd done for her thousands of years ago. Senku then begins on his next project: the age of exploration!
