History

First death

Maeharadeath.jpg

Jun is originally a member of the Nozama Peston Services, and an Amazon hunter. He is untimely killed during the hunters' confrontation with the Dragonfly Amazon, formerly Ryusuke Otaki, attempting to get through to his former comrade only to be mauled by the hungry Amazon. Mortally wounded, Maehara takes solace in that, though fated to die at the hands of one of the beasts, it was Otaki who did so, before he dies. BEAST INSIDE

Revival

Nozama Pharmacy, lead by Yugo Tachibana, then implanted Amazon Cells into his dead body, reanimating him, resulting in him turning into his Amazon Origin Form. He is also seen in a cage, chained, waiting for the moment to go outsideHERO OR NOT

Amazon Sigma vs Alpha

Takaaki Tenjo ordered Shogo Kano to give Jun the newly developed Amazons Driver, allowing him to transform into Amazon Sigma, an Amazon similar in appearance to Alpha and Omega. His first deployment was as a trap to kill Jin Takayama, where Yugo Tachibana sent an e-mail to him,  mentioning "a new type of Amazon". He was easily able to overpower Amazon Alpha, severely wounding him and forcing him to retreat.INTO THE CANNIBAL'S POT

In the next encounter between him and Nozama Peston Services, he then overpowers Amazon Omega, even managing to deliver a near-fatal blow through Omega's torso. JUNGLE LAW

Afterwards, he received a maintenance check in Nozama Pharmacy. His next deployment was to intercept Jin, who was chasing the Tlaloc switch stolen by Shogo Kano. Again, he managed to defeat Alpha even more easily, though this time Jin didn't fall, stating that he simply didn't want to, which the dead would never understand.

Immediately after, Nozama Peston Services and Haruka came, with Jin recovering and joining the fray not long after. In the ensuing battle, Amazon Sigma was able to fight more than evenly against the Alpha-Omega duo, until he was caught off-guard by an electric bullet combination from Kazuya Misaki and Kota Fukuda, his previous teammates. Taking the chance, Amazon Alpha hit him with the Violent Slash, followed by Omega's Violent Strike.

Second Death

Jun killed by Mamoru

Even after all of the punishment he received, Amazon Sigma was still able to stand as if nothing happened. However, it turned out that he just didn't feel pain; his body started to dissolve, the damage to it finally taking its toll. When he realized this, it was too late. Upon him attempting to escape, his torso was impaled from behind by Mole Amazon, killing him. KILLING DAY

The news of his death reached the Chairman of Nozama Pharmacy quickly, who became enraged, thinking that he was being used as an "accessory to failed research" by Yugo Tachibana. He then stated that despite Amazon Sigma's power, a lifeform who doesn't eat is garbage.

It is very likely that the project was discontinued and no other Amazon Sigma was produced anymore, except for one Five years later.

Powers and Abilities

Little was known about Jun's abilities while he was a living human, other than him being a skilled hacker and fighter, as well as an accomplished chess player, the latter of which is often referenced in his fights as an undead Amazon, used for taunting his opponents as to how many moves he would take to finish them off.

As a biological weapon designed and built to surpass the 'old' Amazon in every way, his basic fighting abilities as an undead Amazon is easily on par with that of Alpha's and Omega's, while his lack of morality and sense of pain boosts his parameters significantly, enabling him to easily take on Alpha or Omega on one-on-one fights, and almost defeating them altogether after being upgraded. However, his lack of sense of pain also serves as his weakness as he is unable to gauge the damage he has taken in fights, causing him to overexert himself all the time, thereby taxing his regenerative abilities heavily.

As an undead with no need, as well as being incapable, of consuming food, he is forced to rely on researchers back in Nozama Pharmacy for maintenance of his wellbeing. His overall abilities are also dependent on how good said researchers are at their jobs in maintaining and upgrading him, as he is thoroughly incapable of growth in any way. This makes him a deadly yet easy to control weapon.
