Swiss-Army Weapon: His multi-purpose gun/computer known as a GUMP, which summons demons just as well as it shoots foes.
We Cannot Go On Without You: He dies first in battle or before the actual last party member, it's Game Over. And because he's the only person in Spookies to be able to take on demons, they rely on him all the time just as much as they do with Spooky.
Missing Mom: Nothing is mentioned about her mother except she died after she was born. Her father was living in America before the events of Soul Hackers took place. Thus, her grandmother was her "mom".
Willing Channeler: Later accepts Nemissa sharing her body, and the two talk back and forth and she controls the body occasionally when they aren't fighting.
Awesome, yet Impractical: At lvl. 75, she learns one of three available attacks Naomi possesses (though she has an extra fourth one that would possibly make Nemissa very broken) depending on how Hitomi was described. Unfortunately, these attacks take a long time to learn for the main game but are faster to get during the post-game.
A devil summoner and former employee of the Phantom Society who resigned in disgust to their questionable practices. His Vision Quest provides a password the protagonist need to unlock some hidden features on his GUMP.
Crutch Character: All of the vision quest protagonists qualify as this. Urabe in particular is the first character who is actually controlled in battle, and he's quite powerful compared to the first dungeon's enemies. The vision quest itself let's the real protagonist skip his earliest, most vulnerable levels.
Heel-Face Turn: In the past, which is the result of his family's death.
The second Vision Quest character. An accomplished Summoner and member of the Phantom Society, sent on a mission concerning the Manitou Net. However, he has started to doubt the goals of the group and is reconsidering his membership.
Heel Face Door Slam: Began questioning his allegiance and leaving the Phantom Society after a encounter with Rei Reiho. But dies before he could get the chance.
Real name Masahiro Sakurai, he founded and leads the Spookies from a mobile semi-trailer truck. He's always seen with a cigarette tucked between his lips. At the start of the game, he assists the Protagonist and Hitomi to hack into the mainframe servers of Algon Soft.
Hypocrite: For all his belitting and insulting of Yu-ichi for acting like a kid, he acts just as childish. It's possible that he doesn't want to see Yu-Ichi make such rash decisions after the traumatic experience Six went through when he was a child.
Lovable Coward: His crippling fear of demons quickly becomes a Running Gag. Though it is understandable, considering that, despite his Wall of Weapons, he's vastly underequipped to fight them compared to the Protagonist and Nemissa.
Meaningful Name: His codename comes from "Six shooter", which is slang for a revolver.
Skilled, but Naive: Claims that he's an expert in wielding small arms. Nemissa calls him out since he's not honest about it, which he admits since his combat training didn't prepare him to fight real monsters.
Wall of Weapons: Implied to have a hidden arsenal of small arms (Which are illegally acquired), considering Japan's strict anti-firearm laws.
Dull Surprise: After an ill-fated attempt to confront a villain instead of letting the protagonist handle it he slips into this. The other Spookies figure that it's shock but it's actually a sign that he's been brainwashed. Once the brainwashing is broken, he's actually very emotional about how much trouble he's caused.
Heroic BSOD: If Spooky dies, Yu-Ichi beats himself up over the whole thing.
The Load / The Millstone: He's definitely one of the two. He's certainly a Millstone after being brainwashed, but he was brainwashed in the first place because of his own stupidity.
It's All About Me: While Azazel and Shemyaza are by no means saints, they fully believed in the cause and were willing to die for it. Satanael simply laughs at their deaths and plans on profiting on Manitou only for himself.
Mr. Exposition: Explains what the Phantom Society is and what their goals are. Also touches upon the story of the previous game, comparing its characters to Soul Hacker's.
Transvestite: Rumored to have been in one in Devil Summoner and had Tomokazu Sugita as her voice actor in the Japanese version. Averted in the English version where Tara Platt portrays Ginko as a woman.
A high-ranking member of the Kuzunoha Clan. After saving Hirasaki City from destruction, Rei heads to Amami City to investigate the activities of Phantom Society.
Badass: Fights solo like Naomi, only using her demons to only cast spells.
Jerk with a Heart of Gold: Acts rude and seems like she doesn't care, but looks into things that she feels could help and gets the aid of Madame Ginko when she's worried.
Previous Player-Character Cameo: She was the heroine of the previous game in the series, Devil Summoner, playing a similar role to Nemissa. Briefly summarised by Madame Ginko as her having known 'that boy' (the protagonist of that game) very well.
A Summoner belonging to the Kuzunoha clan.
Body Surf: The current Kyouji Kuzunoha, who switched bodies after Devil Summoners Protagonist took up residence in his own.
The younger sister of the main character. She's an avid tech fan who would rather spend time playing Paradigm X over studying.
Brainwashed: She gets her soul stolen by Snappy in the VR Art Museum.
A guide to the Protagonist again after he helps save Hirasaki City in the first Devil Summoner game. He takes the form of different animals and appears at different points in the story to lead him through Vision Quests.
A Swiss scientist who became obsessed with the possible creation of life, he fled to Japan in secret after he was nearly killed by an angry mob. He offers his services in fusing demons to create better ones.
Corrupt Corporate Executive: Believed to be one by the Spookies after learning the true purpose of Paradigm-X, their tune changes once they meet him. Then he reveals he is as corrupt as previously believed after the Satanael fight.
I Cannot Self-Terminate: Manitou desires death because it cannot coexist with humans, and Nemissa was made to bring the song of death to it.
Non-Elemental: Magic based Manitou uses Armageddon, Demon Birth Cry, Necro Dogma, and Megidoloan. Physical based Manitou uses Abyss of Naraku.
Pure Is Not Good: Manitou is a "pure" spirit and has no sense of self. By itself it's harmless, but when surrounded by the madness of humanity it becomes a raging force. Despite this, Manitou wished to coexist with mankind until it reached a point where the souls it absorbed made this impossible.
The Protagonist of the original Devil Summoner, who inhabits the body that belonged to the true Kyouji Kuzunoha. The original final Bonus Boss for the EX Dungeon in the Sega Saturn and PlayStation versions of the game.
Body Surf: Came to this one after his original body was killed by Sid Davis.
Summon Magic: Summons Shiva, Vishnu, Metatron, Kali, and Anat for the boss fight.
