Agito Makishima(巻島 顎人 Makishima Agito) is of medium build and muscular; he is a third-year student at the same high school the others attend, but looks older. Portrayed as an anti-hero, he almost never allows sentiment to stand in his way.
He appears shrewd and calculating. At one point a candidate-member of the Kronos Elite, he is now viewed by them as a traitor. Even though he may have activated his Unit before Oswald A. Lisker, the second Guyver, he did not openly appear in his Guyver armor until after Lisker was eliminated and thus he was dubbed "Guyver III". Agito shows a frightening knowledge of what the Guyver can do throughout the series.
- After the Kronos conquest, Agito leads a resistance organization known as "Zeus No Ikazuchi" or "Zeus' Thunderbolts", as he plans to overthrow Kronos and steal their power (as the god Zeus did to his father, Kronos).
Once the foster son of a man named Genzo, Agito came to hate the company that the man worked for almost as much as he hated the man himself. Genzo, who had driven Agito's parents into bankrupcy and later suicide, was a greedy, power-hungry man, with seemingly no redeeming qualities at all. Certainly none that Agito could see, or even care to look for.
Agito grew to young-adulthood with the knowledge that too many mistakes, too much defiance, would make him useless to Genzo and he would most likely be killed.
The first time Agito appears in the story, he is seen presiding over a meeting of the Narisawa High School student council. Sho, the secretary of the student council, also makes an appearance.
Manga and OVA series
Agito is first seen in the OVA talking to the Test Type Zoanoid who stole the Guyver Units, promising to help him only after receiving the units (although it isn't made clear until several episodes later that the person on the phone is Agito).
Another day presumably passes after that, because the next we see of him is at the end of school. He passes Mizuki Segawa and another, unnamed, girl in the halls, leading to the discovery that he is rather well-liked among the female population of that school. Stopping on his way out, he gave Mizuki a gentle reminder not to be late for the next meeting of the student council.
However, he was only interested in Mizuki insofar as he could use her to gain the cooperation of Sho, and thus to gain the use of his abilities by proxy. Agito has no real concern for her as a person, though he does put on a rather convincing act. He was once friends with her brother, though most likely just friends of conviniance considering his personality, and he later inquires as to the other boy's health when he and Mizuki are leaving school together.
When he learns that Mizuki has been taken hostage by the Hyper-Zoanoid Zerbebuth, through unknown means but it is likely he was informed by one of his unknowing dupes within Chronos itself, he took action to protect her. Killing the Hyper Zoanoid, he left after exchanging a few cryptic asides with Sho. Given his nature, it is likely that these remarks were calculated to make the younger Guyver more willing to see him as an ally. He eventually betrays Sho after refusing him access to the Guyver Gigantic chrysalis and eventually aquires his own Guyver Gigantic unit and challenges Sho to a final battle in the ruins of Tokyo.
As he has very little interest in mundane affairs, he cuts the meeting short and leaves quickly.
