Prelude of the Chase

Guyot sends a group of chosen Zoanoids, the Lost Numbers, against Sho to keep him busy and kidnap his father, Tetsuro and Mizuki at the same time. Guyver I defeats his three enemies, but Guyot's plan works: Sho must hurry to save his closest friends and his father, now with the help of the mysterious guy that previously helped him.
