The Runaway: Ran away with Yuki-Rin to become a pirate.
Tomboy and Girly Girl: The girly-girl to Yuki-Rin's tomboy. While Molly sometimes wears punk and goth-inspired dresses and is more of The Stoic, Yuki-Rin never wears dresses and is more of a Genki Girl.
Broken Bird: He was shunned by the World Nobles and their families for not acting like them. It is really driven home when Heathcliffe's family - thinking he died - put him in a coffin and sent him to sea when he was asleep. Heathcliffe then had to play his guitar on the streets for money and live alone in filthy, unsafe tenement housings for a year, until Yuki-Rin found Heathcliffe - who was filthy, lice-infested, starving, and begging on the streets - and took him into the crew.
Lonely Rich Kid: A major part of his backstory. Grew up as one of the three sons of Saint Sarutobi, a World Noble. He only had his two brothers, Holden and Soren, to hang out with since the commoner kids shunned Heathcliffe for being a Noble's son and the kids of Nobles shunned him for not conforming to Noble society. Then, it got Invoked hard and Heathcliffe was kicked out of his home and forced to live in filth and poverty for a year, living through hunger, lack of a proper shower, lice, and death. Fortunately, things turn around for Heathcliffe and he's got some good friends (and his brothers and his girlfriend) backing him up.
Unlucky Childhood Friend: She's grown up with Kartik all of her life, and she constantly wonders why Kartik won't take their relationship further. Plus, there's also Karin competing for Kartik's attention.
Heroic BSOD: Occurs in the Project Mei/Time Traveller Arc TWICE. The first time occurs when he time travels with Apple and is forced to see Yulia killing his grandma in front of his eyesagain. The second one occurs later on when Yulia almost dies at the hands of the Arc Villain.
Leitmotif: Ain't no Rest for the Wicked by Cage the Elephant.
Sex Slave: Was nearly forced to become one during the Triad Arc. Thankfully, he escapes from the Dragon Lady's brothel before anything bad happens to him.
Stepford Smiler: Played straight, because Daisuke had to witness his Vitriolic Best Bud, Yulia, kill his grandmother because she was Brainwashed and Crazy when it happened. It's also implied that Daisuke's grandma was either the only relative he had or that his grandma was his last known living relative before her death.
Street Urchin: Implied to be one before joining the Capricorn Pirates.
Arranged Marriage: Her arranged marriage to Gareth and the Capricorns trying to stop the marriage are what fuel the Noblesse Oblige Arc.
Bathing Beauty: Has had the most bathing/showering scenes out of all of the Capricorns.
Break the Cutie: Where do we start? First, her mother dies leaving her an orphan, then she becomes Kaoru and Mina's captive until their Heel-Face Turn, then she is a captive again, but, this time by the Baba Yaga, and, then, she had to face her evil aunt and prepare for possibly leaving the crew because of her Arranged Marriage to Gareth, which never happened.
Broken Bird: Her mother passed away shortly before she and Showtarou ended up with the Capricorn Pirates.
Brought Down to Normal: Happened to her at the climax of the Mr. Chung-Feng Arc where her own father took her spear, broke it, and used the same spear to nearly kill Heathcliffe. She isn't seen fighting again until the Fractured Fairy Tale Arc, where she fights off an Expy of the witch from Hansel and Gretel.
Took a Level in Badass: Occurs in the Triad Arc when she makes the Dragon Lady pay for almost forcing Daisuke to become a prostitute, kidnapping Enlai's sister and murdering his father, and for being indirectly responsible for almost killing Heathcliffe.
Yamato Nadeshiko: Wears a kimono, has long hair, pacient enough for I Will Wait For You' and enough inner steel to be a lady of war. An usual example in that a qippao is her normal attire and she wore the kimono while captive.
Parental Abandonment: Her mother died years before the story began and her step-mother was the Baba Yaga, who was killed when Shikari sacrificed her life by bringing both herself and the Baba Yaga to their deaths inside of a furnace.
Take a Third Option: At the end of the Last Samurai Arc, Rubio was either going to be executed by Kuro or forced to committ suicide to avoid execution. Instead, he faked his death and joined the Capricorns.
0% Approval Rating: Roscoe is most likely the most hated character in the story, mostly because of his actions in the Ginling Island Arc.
The Tuxedo Penguin Pirates
Curtains Match the Window: In an odd way. Kuro and Chernyi have black hair, but their underlings, Ban and Shiro, wear the black clothing in the group. Ban and Shiro are white-haired, and Kuro and Chernyi wear black clothing.
The Baba Yaga (A.K.A. Akari's Mother and Shikari)
Heroic Sacrifice: Commits one for the good of the Kingdoms of Eternal Day and Night.
