A teenage detective is cryogenically frozen by a villainous professor in the mid‑1900s, only to be thawed out in the 2000s by Hikari—the granddaughter of his former assistant. Now adjusting to a world that has changed beyond recognition, he stumbles through modern life with Hikari, turning everyday encounters into a series of awkward and amusing misadventures.
