Zetman

Amagi Corporation

Mitsugai Amagi (天城 光鎧, Amagi Mitsugai)

Voiced by: Shozo Iizuka (Japanese); Steve Kramer (English)

Founder and ex-CEO of the Amagi Corporation, who believed in a distinct divide between the rich and the poor. In the pursuit of his dream to create the perfect artificial humans, he initiated the NET Project, but it eventually led to the escape of his creations, the Players. Having a heavy sense of responsibility for the incident, Mitsugai then commenced Project ZET to set things right, though once again his plans were foiled by the betrayal of Kanzaki. He then became hell-bent on retrieving ZET back after countless failures to create a new one.

Mitsugai's methods were often hard-handed, but after the destruction of his laboratory a second time by Players, he seems to have experienced a change of heart. He then gave Jin a choice of either becoming ZET or living as a normal human, though it is unknown if this is just a facade or not. He has also agreed to help Kouga in any way he can.

Seizou Amagi (天城 清造, Amagi Seizō)

Voiced by: Masashi Hirose (Japanese); Stephen Mann (English)

Son of Mitsugai, husband of Youko and father to Kouga and Konoha. Current CEO of the Amagi Corporation. An arrogant, sober and cold-hearted man and with elitist attitude. Amagi's entitlement attitude is tied in part to his family's name. He was named one of the masterminds of the NET Project by Jirou, but he feigns ignorance to all the various secret projects under Amagi Corp.

Hayami (早見)

Voiced by: Kenichi Suzumura (Japanese); Matthew Mercer (English)

An executive in Amagi Corp. and assistant to Seizou Kouga. He supports Kouga's actions as Alphas, though he only does so to prevent him from taking over Amagi Corp. After being left in a vegetative state, Hayami was brought back by an unknown individual, revealing to Kouga that he was in league with him in a plan to bring down the Amagi clan, which would allow Hayami to take position as the new C.E.O. of Amagi Corp. Soon after his revelation to Kouga, he injects him with one of the insects made by a clone of Ichirō, in order for Kouga's body to reach superhuman levels and help him achieve his agenda. Afterwards, Hayami, Seiji, and Suzuki ("Katou") launched a terrorist attack on a New Year's Eve party that Seizou is hosting, in an attempt to make Seizou confess to all the injustices that he committed on film. One of the hostages tried to grab a machine gun from one of the underlings, and in the chaos, Hayami was shot in the chest and seemingly killed.

EVOL

EVOL leader (マスター, Masutā)

Voiced by: Kōji Ishii (Japanese); Taylor Henry (English)

The mysterious leader of EVOL, he intends to conquer the world and wipe out humanity. It is unknown what the extent of his power is, though he has the power to keep Players from reverting, and his Player form was modeled after a wolf (while he was fully organic). He was one of the original 13 Players that rebelled, and the creator of the G2 and G3 Players.

Seiji Haitani (灰谷 政次, Haitani Seiji) / Anvil (エンヴィル, Envuiru)

Voiced by: Kōji Yusa (Japanese); Keith Silverstein (English)

The brains of EVOL. He seems to have an interest in Jin, as he implanted a ceramic spike into Jin's heart in order to allow him to freely become ZET. He is shown to be merciless when it comes to getting what he wants. As Anvil, Haitani appears as an angelic being with demonic wings, the complete opposite of Inzen's Degel form. He has even stated that his powers are the opposite of Degel's, so they are pretty much neutralized by each other. The eye in the middle of his chest, if gazed into by Inzen/Degel, is able to keep him frozen in place. He desires to become one with Degel, though is unable to because of their opposing natures.

The Sweeper (掃除人, Sōjinin)

Voiced by: Rikiya Koyama (Japanese); Marc Diraison (English)

Little is known about him except for his appearances to kill off defective Players and that there are dozens of him. He also shows some interest in ZET and wishes to fight with him.

Souya Inzen (陰禅 宗弥, Inzen Sōya) / Degel (デゼル, Dezeru)

Another high ranking EVOL. He and Seiji are two of the three main EVOLs, along with their mysterious leader. He is shown to disapprove of the tactics Seiji uses to get what he wants, and is weary of him doing whatever he wants. He is also a firm believer of the ends justifying the means. Inzen is shown to be strong enough to defeat Kouga/Alphasz in an instant. When he first appeared, he and Kosuri/Bat Player kidnapped the creator of the "Ginga Chōjin Alphasz" anime series for unknown reasons. He later appears during Haitani's attack on Amagi Corp., intent on ending the rogue Player for his betrayal as well as kill Jin, believing him to be too dangerous to allow to live.

As Degel, he appears in a towering demonic form with angelic wings, the complete opposite of Haitani's Anvil form. He is also able to shoot demonic-appearing rods out of his hands, which have the ability to transform into soldiers that follow his commands.

Other characters

Jirou Nakata (中田 二郎, Nakata Jirō)

Voiced by: Katsunosuke Hori (Japanese); Dave Mallow (English)

The father of Ichirou, one of the Players. Jirou is a former scientist of Amagi Corp. and an expert in researching the creation of the Players. He admits that the only people he ever cared for were his wife and son, and was devastated when he witnessed his son's murder. When he discovered that the Players were to be used as a means of entertainment, he spoke out against the idea to Kabe, and was sealed inside his underground laboratory soon after, along with the corpse of his son. He soon revived Ichirou by turning him into a Player, and the two survived in the laboratory for sixteen years on nothing but water and medications. When they were set free, he began to plot his revenge against Amagi Corp., along with Ichirou and Katou, a greedy Amagi employee.

Gorō Kanzaki (神崎 悟郎, Kanzaki Gorō)

Voiced by: Mitsuo Senda (Japanese); Adam Nevel (English)

A pioneer in both the NET and ZET Projects in the Amagi Corporation, Kanzaki escaped with an infant Jin in defiance to turning his 'child' into a killing machine. Later disguised himself as a homeless old man and posed as the grandfather of the growing Jin. He was killed in a bid to protect Jin from an awakened Player. Kanzaki's head was however retrieved by the Amagi Corp. and hooked up to a computer so as to obtain unknown information about ZET/Jin.

Akemi Kawakami (川上 明美, Kawakami Akemi)

The foster parent to Jin after Kanzaki. Always addressed as "old lady" or "auntie" by Jin, Akemi was an ex-hostess who had a son she lost custody of to her ex-husband. Her face was slashed by a crazed client, who in turn suffered near fatal injuries by a young Jin, having recalled how his grandfather was killed. She has been selling crepes at a roadside stall ever since. She was seemingly killed right in front of Jin's eyes in a bid to let Jin return to the Amagi Corp., but was later revealed by Mitsugai to be alive, and was given back custody of her son with the help of Amagi Corp.

Youko Amagi (天城 葉子, Amagi Yōko)

Voiced by: Aya Hisakawa (Japanese); Cricket Brown (English)

Seizou's wife, and mother to Kouga and Konoha. She was chastised by Mitsugai for doing volunteer work in secret, resulting in Konoha's childhood trauma. She then ran away from home while continuing her volunteer work, and never returned. However, she and Seizou are not officially divorced yet. It is eventually revealed that she has been staying at the home of her lover, Suzuki. She and Konoha are soon kidnapped by Seiji and Suzuki, the latter revealing that Seizou funded human experiments on his wife and his son, Katou. Soon afterwards, Amagi Tower starts to be destroyed, and in the chaos, she is seen falling into an inferno, but she was saved by Suzuki.

Satoshi Suzuki (鈴木 聡史, Suzuki Satoshi)

A friend of Jin's and Youko's lover. After Youko ran away, she went to live with him, where they continued to help the homeless. After Jin was nearly captured, he offers him and those with him sanctuary. Soon afterwards, it is revealed that he is working with Seiji, and the two of them kidnap Konoha and Youko. During Seiji's planned attack on Amagi Corp., he reveals to Seizou, Youko and Konoha that Seizou's funding of human experiments cost him the lives of his wife and his son, Katou. Thus, he reveals that he was Katou, the mastermind behind the incident with Jirou.
