Hollywood Tone-Deaf: One method of getting Demons to join you is by having him sing to the demons, then the demons will do anything just so that he'll stop.
Hurting Hero: After he finds out (from the horse's mouth no less) that his mother was devoured alive by a demon. It's worth noting that the demon says "Aw, what's with that face! Come on, there's no reason to be sad. You'll see her soon enough... in my stomach! Until then, why don't you entertain me for a bit!! I hope you taste as good as she did!".
Possibly his feelings over having to kill the Law and Chaos Heroes, as they were his friends.
The Heroine is the leader of an underground resistance movement against Gotou. Although she cannot use the Demon Summoning Program, she has incredible magic powers. She eventually becomes the main companion to the Hero.She saves the Hero, Law Hero and Chaos Hero from the end of the world by teleporting them to Makai and is killed in the Great Destruction. She is reincarnated years later and (incorrectly) declared the Messiah by the Messians, but is captured by Ozawa's forces and put under the control of the Psycho Diver, who (under coercion from Ozawa) implants a demon inside her mind that slowly consumes her from within. Her psychic cries for help damage the Hero during each Full Moon until she is rescued.
Color-Coded for Your Convenience: Feel like going for Law? No probs! Shes got a lovely white and blue Templar cape. In a chaotic mode? Atlus has her decked out in a charming red and black combat suit under the cape. Neutral? Law and Chaos in Balance is the Neutral message in this game.
A young man who meets the Hero while searching for his girlfriend (who coincidentally shares the name of the Heroine). He survives the end of the world and gravitates towards the message of peace broadcast by the Messians.He saves the Hero in a Heroic Sacrifice and is reincarnated by divine power into the Messiah, The Chosen One of the Messians. Although he begins as a kind and well-intentioned soul, his viewpoint is poisoned by the Knight Templar angels until he becomes just as radical and unforgiving as they are. He dies in every route: slain by Chaos Hero in the Law route, and by the Hero in the Neutral and Chaos routes.
"Is this what...Is this what God wanted...? I'm...going to die...again? Wasn't I chosen by God... to offer him everyth...!! So that's it...Now I see I was nothing but a sacrifice. Nothing but a pawn to... accomplish God's ends... To be discarded at any time..."
A young and reckless gang member who is first met while he is being beaten up by Ozawa. Although he talks big, he is cowardly and wishes for the power he does not have.He survives the end of the world and eventually decides to fuse himself with a demon, gaining incredible power and ditching the Hero. He then joins up with the Gaian armies in his pursuit of more power, though remains somewhat affable with the Hero. In the Law and Neutral routes he is slain by the Hero. In the Chaos route, he is killed when he greedily snatches a powerful artifact called the Devil Ring from the Hero, and is consumed by its power.
"...So, my end comes as well... In the end, I couldn't beat you, [Hero]. You always were a step ahead of me. And I thought that I had finally gotten power that surpassed God's too ...Was this all... just a dream...? A nightmare...? No... It was a good dream... Goodbye, [Hero]..."
Freudian Excuse: He's been bullied by everyone. THAT'S why he's so power hungry.
Freudian Slip: "Now I have the power of a demon...!!! Now...Now no one will be able to pick on-DEFEAT me."
Hypocrite: After acting as The Load to you for the first quarter of the game, he has the gall to abandon you after gaining demonic power because you would only "slow him down".
An alluring young woman aligned with Gotou who pledges eternal allegiance to the Hero. For this reason, she is incredibly jealous of the Heroine.Her true identity is Lilith, the biblical serpent that tempted Adam in the Garden of Eden. Believing that the Hero is the reincarnation of Adam, she wishes to be his partner so that they can create a new world together. She is killed by the Hero in the Law and Neutral routes, but steps aside in the Chaos route so that the Hero can be happy alongside the Heroine.
But Thou Must: You're not allowed to choose her as a love interest.
Even Evil Has Standards: "You... You killed Chaos Hero... How can you live with yourself!?! Killing your friend with a straight face!? Have you no remorse!?" Coming from a demon that was willing to Murder the Hypotenuse that's pretty damning.
The wheelchair-bound genius who created and distributed the Demon Summoning Program. He was also the inventor of a teleportation system that inadvertently opened a portal to the underworld, setting off the events of the game. Bears absolutely no resemblance to Steven Hawking.
A Jerkassgang leader. He turns out to have a remarkable talent for Summoning and allies himself with Gotou.He survives the end of the world and strikes a deal with the new demonic regime so he can rule over the district of Shibuya. After Chaos Hero fuses himself with a demon, he kills Ozawa out of revenge.
Asshole Victim: When he dies, you really can't feel sorry for him. Even the Law Hero doesn't register a complaint over if the Chaos Hero kills him.
After demons begin to appear in the streets of Tokyo, the player can go to Inogashira Park and meet an old man who speaks cryptically of the hero gaining great power and of a choice between Law and Chaos. He then conjures up a vision in which the hero, Law Hero and Chaos Hero fight against the devil summoner Douman and are soundly defeated. The vision ends and the old man tells the hero that he is too weak to fight Douman, but that they will likely fight again and that he must be careful.After arriving in the post-apocalyptic world, the player can find the same old man in Ginza, where he will tell the player to return if no path forward seems possible. If the player then says both Echidna and Haniel, the old man will reveal a secret path to the otherwise inaccessible Cathedral.Near the end of the game, as the player prepares to battle Archangel Michael or the Asura Lord/Ahura Mazda, the old man reveals himself to be 太上老君 - shortened in the AGTP translation to Taijorokun (it should be Taijo-rokun, or Tai Shang Lao Jun). After both are defeated (at the end of the Neutral path), he appears in the ending to comment on the risks that the plans of Law and Chaos posed to the future of humankind, and urges the player to help shape that future free of the influence of outside forces.
Badass Creed: In the Neutral ending, on the need for a balance between Law and Chaos.
Expy: Not of any specific person, but he is basically supposed to support Taoism, a belief based entirely on balance.
