Badass Nickname Vampire refers, here, not to undead bloodsucking creatures, but to the leader of the Mafia in Judoh.
Berserk Button Woe be to you if Clair thinks you're being someone/something you're not! There's some Irony there, as he carries more angst than he lets on
Eye Scream His left eye is needed to open a safe protected by a retinal scanner. He's rescued by Daisuke, who needs to keep him safe in order to (hopefully) obtain some information from him when he comes out of the Angst Coma.
Foe Yay Many fans like to pair him with Daisuke. Generally, Wimpification ensues.
Likes Older Women (manga version only) Has a girlfriend or "friend with benefits" (it's never explained which, though this troper would guess the latter) who is in her mid-to-late-20's, and he's 19.
Hollywood Pudgy Spends an entire manga dieting (read: starving herself) to look good in a bikini to impress her crush at a pool party turns out he wasn't even there! even though she's really not fat.
Our Werewolves Are Different: Started off as completely human, then surgically and genetically altered as punishment for murder to have the head of a wolf, which he disguises with a holographic mask.
Broken Bird She lost her father at a young age. J is sort of based off him.
Christmas Cake Although, strictly speaking, she has another year to go before reaching true Cake status, she does receive comments from J about her lack of a husband. She takes it with a grain of salt, though.
Just a Kid Even though she's only 10, she has to earn money to support her family, because of her alcoholic mother and her Disappeared Dad. Because of her difficult life, she is more adult-like than kid-like, but is dismissed as this because she's only 10.
Wise Beyond Their Years Is able to discern that a man her mother has started seeing is nothing but trouble long before her mother, or even Daisuke does
Gory Discretion Shot Ian is shot by Senator Noriega while spying on him. Afterwards, his hand with the Phi Beta Kappa ring on it is chopped off, packaged up, and sent to Clair's office. All we see is the look of horror on Clair, Giovanni, and Mitchal's faces when they open the box.
Promotion to Parent Adopts Monica, because he sees that she is suffering (and far too jaded for a 10-year-old) without a father figure (or a good mom) in her life.
Everyone Calls Him Barkeep: She is known only by her title "Hime" ("Princess"), as amongst her people, only family members and spouses have the right to know each other's real names.
Space Amish: Her civilization lives outside the city limits, independent from Judoh's technologies. It is, however, a Crapsaccharine World, because its people are very cold towards one another
Gossipy Hens: Makes them good informants for Daisuke
Hooker with a Heart of Gold: No one comes right out and says it, but it is implied that they are prostitutes. (Most evident when they are seen going to a hotel with some businessmen.)
Broken Bird: It's implied that many of her current problems (drinking, poverty) are because her boyfriend (Monica's father) left her.
Children Raise You: Because of her drinking and generally irresponsible behavior, she cannot take care of herself. It's Monica that brings home the bacon and cooks it.
Love Makes You Stupid: Gets involved with a man who wants nothing more than to take her out of Judoh to either be killed or used as a Sex Slave, and doesn't realize it until it's too late.
Mama Bear: At times, such as when Daisuke tries to adopt Monica.
Missing Mom: Is prepared to leave Judoh with her new boyfriend, with or without her daughter
Naïve Everygirl: Despite being an adult and having a child, she still has shades of this trope.
Omniscient Morality License: Takes one anyway (see above), believing that Monica will join up with her later on and accept Christina's boyfriend as her father.
Second Love: Eventually begins a relationship with Edmundo
Stripperiffic: Is seen walking around in public wearing booty shorts on a date, and usually wears a slinky nightie.
Heel Face Turn: Used to be a prominent member of the Mafia, but became disillusioned and gave all of that up. He is now "retired", and supports himself by running a store.
Jerk with a Heart of Gold: Took Daisuke and Shun in when their father was killed, and gave Clair a place to stay after Noriega took over
