Tetsuro is a chubby third-year student and is Shō&#039;s closest friend. He is highly intelligent, keeps his hair cut short and wears glasses. Tetsuro is a Science Fiction fan and the leader of the Sci-Fi society club in the school, which gives him some knowledge to make quite a few assumptions about the things involving the Guyver. 

Lurking under the facade of everyday life lies a dark world of pain and destruction.​ The world is controlled by a sinister brotherhood that hides their fangs behind masks of humanity.​ They are the Chronos Corporation.​ 
 
While investigating a mysterious explosion near his school,​ Sho Fukamachi happens upon the Chronos Corporation's greatest weapon: a techno organic suit of bio armor known as "the Guyver.​" But Chronos is determined to conceal their secrets at any cost.​ Sho soon finds himself relentlessly pursued by its army of horrific bio-monsters.​ With nowhere to run,​ Sho is forced to call upon the fearsome power of the Guyver and rip his opponents limb from limb in a desperate struggle for survival.​

To retrieve the object, they send out vicious monsters known as Zoanoids. So no one is safe in Sho's life; not even himself.

No one close to Sho is safe from Chronos. He must fight.
