    Kenji and his former classmates 

Kenji Endou

  • Action Survivor: When shit starts happening, he's just an average guy with no special skills who really believes in justice. He still Jumps At The Call, because somebody has to do it, and slowly becomes a Bad Ass.
  • Adorkable: Both as a kid and as an adult, he doesn't mind making a fool of himself if he believes that it's the right thing to do or that it will be fun. It's one of the main reason people like him and he ends up becoming The Leader.
  • Anti-Hero: Starts out as a former rock guitarist now living with his mother and working at a convenience store. He later starts La Résistance, and finally becomes a Rock and Roll Messiah!
  • Badass Biker: How he enters the stage at the beginning of the third arc. Of course, his Badass Bike is out of gas after a couple of panels.
  • Badass Pacifist: When confronted by a self-appointed Card-Carrying Villain, who's acting as an Evil Overlord of sorts and who killed his sister's fiancee, Kenji still refuses to fight and brings him down by talking.
  • Breaking Speech: During the third arc, he manages to Drive To Suicide a guy who spent his whole life trying to be a villain simply by explaining to him how pointless his way of life is and how he comes off more pathetic than menacing.
    Kenji: "It's not that easy to be evil incarnate, is it? Personally, I think it's easier to be a man of justice."
  • Cool Shades: Wears them during the third arc, part of his new Rock'n Roll persona.
  • Decoy Protagonist:
    • Once the first story arc finishes, the story stops focusing on Kenji to shift to Kanna for most of the remainder of the series.
    • Subverted: During the last third of the story, after everybody finally accepted his death, he comes back to be a protagonist again.
  • Determinator: His main trait, even noted as such in Friend's virtual reality game.
  • The Hero: As a kid he loved heroes, always wanting to play as one in pretend games. As an adult, despite being an underachiever in his daily life, he demonstrates he is willing to be truly heroic when the situation calls for it.
  • Not Quite Dead: At the beginning of the third arc it turns out he survived his apparent death, though he needed several years to come to terms with his failure.
  • Messianic Archetype: Finds self in the desert, spends three days simply grieving, seemingly dies and comes back to save the world?
  • Nice Hat: Eventually gives it to Kanna as a memento.
  • Our Hero Is Dead: At the end of the first arc. Several characters spend the whole second arc coming to terms with this.
  • Took a Level in Badass:
    • During the first arc he takes a couple of levels after founding La Résistance, even physically training himself.
    • When he returns for the third arc he hasn't gained any new skill, but he has pushed his Determinator trait to its extreme.

Otcho (Chouji Ochiai)

  • The Atoner: After indirectly causing his son's death, he spends the rest of his life trying to atone for it.
  • Bad Ass: He's definitely the strongest and most skilled of the main characters, and probably the smartest. He's essentially a ninja in a modern-day setting.
  • Badass Beard: When you put a Bad Ass in prison for several years, you get this. He never bothers shaving it after his escape.
  • Badass Longcoat: He wears this all the time after his Training from Hell.
  • Badass Grandpa: During the second and third arc he's visibly old, but he doesn't seem to have lost even a bit of his strength and skills.
  • The Berserker: In Friend's virtual reality game, and occasionally in real life.
  • The Lancer: Both in his childhood and as an adult in the La Résistance. Despite being the smartest and strongest member of the group, Otcho acknowledges that Kenji is the better leader; other characters often informally treat Otcho as the second-in-command, especially when Kenji isn't there.
  • Parental Neglect: He spent so little time with his family that his son thought a stranger was his father and chased him into the street, where he was hit by a car. Otcho blames hiself for his death.
  • Red Baron: He's called "Shogun".
  • Salaryman: Originally was one, but quit after he realized the effect his workaholism had on his family.
  • Simple Staff: He's skilled with a bo, but usually uses a pipe instead of a wooden one.
  • Training from Hell: He went through this as part of his atonement, then used his new skills to mantain a bit of order in a very poor and unruly part of the city.

Yukiji Setoguchi

  • Cool Old Lady: After the timeskip. Her physical strength doesn't come into play often, but her inner strength and determination are very notable to the end.
  • Cute Bruiser: As a child she was the strongest of Kenji's group.
  • Parental Substitute: She is this to Kanna during the first timeskip, after Kenji's disappearance.
  • Old Maid: Even after the timeskip it's shown that she never married.

Yoshitsune (Minamoto)

  • The Chains of Commanding: He really doesn't want to be the leader after being separated from the rest of the group, especially since the job requires a great deal of pragmatism he's frankly too nice to be comfortable with.
  • Heroic Self-Deprecation: At first it's just regular Self-Deprecation but as time goes by and he reluctantly becomes leader of the heroes it turns into this.
  • Rebel Leader: After Kenji's death and Otcho's capture, he's forced into this.
  • Reverse Mole: He infiltrates Friend Land by working there as a janitor.
  • Salaryman: Before joining La Résistance he's a pretty pathetic example of this.
  • Took a Level in Badass: After the timeskip he becomes legitimately badass in his own quirky way.


  • Big Eater: One of his most noticeable traits since he was a child.
  • Flashback Echo: He seems to develop post-traumatic stress disorder after the Bloody New Year's Eve.
  • Taking You with Me: Comes very, very close to doing this with Friend and a bomb. Remembering Kenji's words about not hurting innocents convinces him not go through with it at the very last minute.

Mon-chan (Masaki Shimon)


  • Creepy Child: When he was a kid, of course.
  • Mad Scientist: He considers it a game to make as terrible a virus as possible to see how long it will take Kiriko to develop a vaccine for.
  • My God, What Have I Done?: His reaction to finding out Friend planned to kill 99% of the world's population.


  • Animal Motifs: With the frog, both in looks and name ("kero" is the Japanese onomatopoeia for a frog's croak).
  • Badass Normal: Lacks the kind of training that Otcho has, but still rushes into a burning factory to save lives regardless of his burns.
  • Gonk: Sort of. Keroyon isn't hideous, but he has a very froglike visage.
  • Refusal of the Call: Ignores Kenji's request to stop Friend, and terribly regrets it.


  • Attention Whore: His desire to rule the world is due to him wanting to be the center of everyone's attention and admiration.
  • Big Bad: He decides to be this to Kenji's Hero.
  • The Bully: He was quite a jerk as a kid. Notably, he's the one directly responsible for Katsumata's Start of Darkness.
  • Dead All Along: Turns out Friend did die before thing started falling apart.
  • Rival Turned Evil: He pushes his childhood rivalry with Kenji to utterly insane heights.

Donkey (Saburou Kido)

  • Agent Scully: Even as a child he firmly believed in science over superstition.
  • He Knows Too Much: What ultimately leads to his death is the fact that he happened to witness Fukubei's faked "miracle," and would know that any other resurrection he would have as Friend would be fake as well.
  • The Pigpen: As a child he didn't take many baths.
  • Posthumous Character: His death starts the story.

Sadakiyo (Kiyoshi Sada)

Yanbo and Manbo


    Other good guys 

Kanna Endou

'God/Kami-sama' (Kamigama Kyutaro)

Shouhei Chouno



Kyoko Koizumi

Father Nitani

Father Luciano

The Pope

  • Too Good for This Sinful Earth: To the point that after the second major Time Skip near the end, he's the only one close to having enough clout to match Friend's.
  • My God, What Have I Done?: Realizes sometime after after Friend's "ressurrection", that the man was a fake who was planning something terrible. This is what led to his near poisoning so he could be replaced with a Friend-allied clergy.


  • For Science!: One of the primary reasons for making his giant robot: he thought the fake one was such a piece of crap that he felt obligated to make a real one.
    • It was probably all he had left, given he eventually realized (off-screen) that his daughter wasn't being held hostage, but had actively joined the Friends.

Haru Namio

  • Chekhov's Gunman: Appears early on as a successful enka singer who works with Friend, Later revealed that he's protecting Maruo and helping the La Résistance covertly.
  • Stepford Smiler: Subverted when he turns out to be one of the good guys. Then you realize it's probably necessary to get close to Friend.
  • The Atoner: Left Kenji's band to join another and felt obligated to help him when the time comes.
  • Reverse Mole
