Kazuki Komon

Portrayed by: Takuji Kawakubo

"The reality one sees...if it were all a deception..."

The main character of the series. Komon is a kind-hearted, straightforward person who is always willing to help others. Throughout the series he bonds with the Dunamists and grows alongside them. This culminates in him becoming the fifth and final Dunamist, host to the true form of Nexus: Ultraman Noa.
  • 10-Minute Retirement: In episode 16, he leaves the Night Raiders but returns at the end of the episode.
  • Adorkable: Komon is a Nice Guy, but rather straight-laced. Also, there is his reaction when he gets tomato ketchup on his nose during a dinner in episode 30.
  • Alliterative Name: Kaizuki Komon.
  • Armor-Piercing Slap: Komon gets one from Nagi in episode 13. She was trying to snap him out of his grief for Riko's demise.
  • Bad Liar: This is a given, as Komon is a naturally straightforward person. He lied to Ren's boss that he was Ren's cousin, something that Ren joked about upon hearing about it. Even Ren's co-worker remarked on how Komon used honorifics when referring to his 'uncle and aunt'.
  • The Big Damn Kiss: Shares one with Riko in episode 10. Then, she dies 2 episodes later.
  • Catapult Nightmare: Has one in episode 7 where Nagi shot him.
  • Dark and Troubled Past: When he was a child he almost drowned. In episode 1, he is terrified and loses control of himself during a rescue operation taking place near a river.
  • Friend to All Children: Komon goes out of his way to rescue a girl trapped in a factory with her dog in episode 7. He meets up with her in episode 8 and proceeds to have a chat with her, but the Memory Police had already erased the girl's memory.
  • The Hero: Despite not being a Dunamist at first.
  • Heroic BSOD: Goes through one as a result as a result of Riko's death in episode 12. It is only in episode 16 when he gets back to his normal self.
  • Inner Monologue: As the main character, he has plenty of these.
  • Instant Sedation: When he wakes up in the middle of his physical examination in episode 1, he is quickly sedated before he can ask more questions.
  • It's All My Fault: For a while, he believed that Riko's death and a family being attacked by Nosferu in episode 12 happened because they cross paths with him.
  • Lotus-Eater Machine: Mizorogi conjures up an illusion of the late Riko, making Komon think that he can reunite with her.
  • Masculine Girl, Feminine Boy: Feminine Boy to Nagi's Masculine Girl.
  • The Medic: Komon used to be in a rescue team, so he was able to patch up an injured Ren in episode 27.
  • Naïve Newcomer: At first, because he is new to the fact that TLT and Space Beasts exist.
  • New Meat: Night Raiders' newest member. The start of the series highlights his unfamiliarity with the ways of the Night Raiders and TLT.
  • Nice Guy: Easily the best example in the show. He's straightforward, always willing to help others, bears no ill will towards anyone and is also quite empathetic.
  • Parental Abandonment: His girlfriend Riko's family is shown a few times, but there is hardly any mention about Komon's parents. However, he was shown on the phone with his mother in episode 13 and she seemed to care about him.
  • The Power of Hate: Nagi tries to get him to cultivate this. On the other hand, Himeya wants Komon not to give in to his hatred.
  • Say My Name:

    Komon: Riko!
  • Sensitive Guy and Manly Man: From his dialogue with Himeya in episode 15, he sees himself as the Sensitive Guy to Himeya's Manly Man.

    Komon: I'm not a strong man like you.
  • Strapped to an Operating Table: In episode 1, when TLT perfoms a physical examination on him. When he wakes up in the middle of it, he is understandably upset and confused at the situation.
  • Supporting Protagonist: Played straight, making Nexus the first show in the Ultra Series to use this trope. The story is told mainly from Komon's point of view, even though he is not a Dunamist (in other words, he does not transform into the titular hero).
    • He loses his role as this when he eventually becomes the fifth Dunamist in the final episode.
  • The Lost Lenore: His girlfriend, Riko. The fact that she was Dead All Along and was actually Dark Faust shook Komon considerably. Took him quite a while to get over that.
  • This Is Unforgivable!:
    • He is visibly angry with the Memory Police for erasing the memory of a girl he rescued in episode 8. The MP leader showed him why it was needed, which gave him second thoughts.
    • This is clearly on his mind when Mizorogi taunts him about making Riko his People Puppet in episode 13.
    • In episode 25, he says it out loud to Mizorogi after witnessing a defeated Ultraman.
  • The Watson: Justified, as he is new to the Night Raiders and TLT.
  • Wrong Genre Savvy: As a character, Komon would fit nicely in a typical Ultra Series, something which Nexus is not.
    • He is fortunate enough to be the first person to encounter Ultraman. After being saved by him in episode 1, he firmly believes that Ultraman is on the side of good and is upset when the other Night Raiders, especially Nagi do not support his belief.
    • In episode 3, he is surprised when Nagi revealed to him that Space Beasts attacks are covered up and that the victims' families do not know the truth of what really happened to their loved ones who are killed by Space Beasts.
    • In episode 8, he is happy to meet up with a girl he rescued during an operation. He expected her to recognize him and to name her dog with the name his suggested, much like how a typical Ultra Series episode with a Victim of the Week would end. Instead, he finds that her memory has been erased.

Nagi Saijyo

Portrayed by: Yasue Sato

The deputy leader of the Night Raiders. She is very strict, especially to Komon and can be quite brutal in certain situations. She is driven to fight by her hate of Space Beasts, stemming from incidents regarding her childhood and her former lover Shinya Mizorogi.

  • Anti-Hero
  • Armor-Piercing Slap: Gives one to Komon in episode 13 to snap him out of his grief for Riko's demise.

  • Commander Contrarian: Stubbornly refuse to entertain the idea that Ultraman is not evil.
  • The Cynic: Even though she has seen Ultraman destroy many Space Beasts, she explicitly express her distrust against them. This is one reason why she does not get along well with Komon.
  • Dark and Troubled Past: The murder of her parents and seeing her former lover go to the dark side.
  • Determinator: In her crusade against the Space Beasts.
  • Fantastic Racism: Her mother's death at the hands of an inhuman being lead her to have a seething hatred of the Space Beasts and anything inhuman in general.
  • Good Is Not Nice: Not the nicest girl around, but firmly on the side of good.
  • In the Back: Shoots Mizorogi in episode 18. It did not kill him.
  • It's Personal: When Mizorogi is involved.

  • Masculine Girl, Feminine Boy: Masculine Girl to Komon's Feminine Boy.
  • Parental Abandonment
  • The Power of Hate: Her immense hatred of Space Beasts is what drives her to take her job as a Night Raider very seriously. Revealed to have been invoked by Dark Zagi so that she would become a Dunamist.
  • Selective Obliviousness: She is steadfast in her belief that Jun Himeya / Ultraman is an enemy, even though there is evidence to the contrary.
  • The Smurfette Principle: Averted, as there is also Shiori Hiraki. Played straight in flashbacks, where she was the only woman in the team, the others being Captain Wakura, Ishibori and Deputy Captain Mizorogi.
  • Sour Outside, Sad Inside
  • This Is Unforgivable!: It's on her mind when it comes to the individual who murdered her mother.
  • Tomboy and Girly Girl: Nagi is the tomboy, Shiori is the girly girl.

  • Tritagonist: After Komon and the Dunamists.
  • Missing Mom: When she was young, her mother was killed by a being resembling The One.

  • You Killed My Mother

Jun Himeya

Portrayed by: Yusuke Kirishima

The second Dunamist and the first one seen in the show. He is a serious, somewhat brooding individual, not given to trusting institutions such as the Night Raiders.

  • Intergenerational Friendship: Forms one with Sera, a young girl who lost her family in the war and treated him when he was injured. He became a big brother figure to her.

  • Leave Me Alone!: To his former colleagues, Negoro and Sakuta.

  • Survivor Guilt: Himeya never forgave himself for Sera's death during the war.

Ren Senjyu

Portrayed by: Masato Uchiyama

The third Dunamist, Ren is outwardly, cheerful, optimistic and simple to the point of ditsy — this, however, conceals his past experiences. He receives the Light after Himeya's disappearance.
