Brother-Sister Incest: Shizuka has her own ending of sorts, though they're not related. But Chris and Arata have the same father and their mothers were sisters (which means that Chris and Arata have the same four grandparents).
Elephant in the Living Room: The game makes no attempt to address the ick factor surrounding the fact that the deeply in love Chris and Arata are both half-siblings and cousins.
Forceful Kiss: During the second half of the game in the Angela "route" she says that she's not willing to sacrifice her chastity just to save Chris. Arata makes a bet that if he can make her open her eyes within one minute she'll agree to help and he kisses her, winning the bet.
Jumped at the Call: Arata's response to being placed into a life or death situation fighting giant monsters not of this world is to find it totally awesome. Not to mention begging Chris to fight in the Waltz together.
The Crown Prince of Eldhiland, and the main love interest of the story. Chris transfers to Arata's school one day, has all the girls in an uproar over his handsomeness, and accidentally drags Arata into the Princess Waltz when he drops one of his rings, only for Arata to put it on. After a great deal of arguing and heroic stupidity, the two of them decide to team up, and realize that together they are capable of transforming into the super-powerful princess of the sword, Iris.Chris is very hung-up over his princehood, and is fighting in the Princess Waltz for reasons that Arata does not immediately grasp. As the tournament proceeds, it's revealed to the player that Chris has deep insecurities that stem from the fact that he is unable to properly inherit the throne, due to being born female.
Voiced by: Haruka Sawai
A Date with Rosie Palms: Due to the synchronization effect, Chris ends up becoming highly sexually aroused and barely manages to avoid detection.
Badass: While not on par with the princesses, Chris is a fairly capable fighter.
Bifauxnen: Chris acts very much like a male and a prince.
Bokukko: He was raised to be a prince all his life and thus speaks like a polite boy.
Damsel in Distress: Whenever Chris is not combined with Arata to be Iris, he will get himself into massive amounts of trouble. Humans (and princes) are just that weak compared to the generic monsters of the game, let alone the princesses.
Heroic Bastard: Cecelia, Chris' mother, was the younger sister of Princess Lydia of Soldia, winner of the previous Waltz. Jealous of her sister & desiring the Emperor, she had an affair with him, which brought forth Chris.
Heroic Sacrifice: Given a sadistic choice by the Big Bad to kill Arata and absorb the remnants of his power, she instead turns her sword upon herself.
Raised as the Opposite Gender: The Emperor is only supposed to have one child and it is always to be a son. However, Chris is female but was raised as a boy to participate in the Princess Waltz in the blind hopes that somehow everything would work out.
Sweet Polly Oliver: Chris has always dressed in masculine clothing in order to attain his ideal of becoming a true prince.
Tsundere: Chris is rather abrasive towards Arata, which he lampshades even before The Reveal.
Useless Useful Spell: The Prince's Blessing. It's supposed to keep him alive at all costs, but the darn thing just can't keep up with some rates of damage. The fact that she only has half the Blessing is probably part of the problem.
Angela Victoire Blendin
The Princess of Agnis, who entered the Princess Waltz just to have fun fighting. She's rather bloodthirsty and enjoys battle more than anything else, and expresses no interest in Chris, even though that's the goal of the tournament. She's known as the Dragon Princess among the others, and is a very formidable opponent; she wields a burning lance called Perpetuelle.Angela is noted for being hard to get along with and tends to blatantly ignore her adviser, Glen, but when the mood strikes her she can be very kind. She also has a bad habit of throwing vast amounts of money around, and abusing her special status as a princess when she shops.
Voiced by: Kanami Kono
Animal Motifs: She not only has a dragon motif, but she actually has a blessing from the dragon god.
Badass: She's probably the most badass princess in the war and already a warrior with extensive experience.
Honor Before Reason: Throws the first fight with Iris after surviving Iris' finishing move, even though the unconscious Iris was at her mercy, since she doesn't feel it's honorable to end like that after such a spectacular battle. She also feels that the big bad is disgracing the Waltz and agrees to work with Arata later on.
Hot-Blooded: Angela is very passionate, aggressive and lively.
Jerk with a Heart of Gold: She has an abrasive personality and is quite the Blood Knight, but the very first casual scene of her involves Nodoka. She drags Nodoka along while she goes clothes shopping and then at the end gives her an expensive set of clothing as a thank you for helping her out.
The young Princess of The Earth, who hails from the country of Shihou. She has known Chris since they were young children and has devoted herself entirely to Chris, being more intent on becoming his wife than any other princess, although she doesn't know about Chris' true biological sex. Once she arrives in the story, she initially gets along well with Arata before growing jealous, a trait which marks her behavior with the other princesses as well.Contrary to all expectations as she's quite a small girl, Suzushiro holds massive physical strength to compensate for her mediocre speed and poor defenses.
Voiced by: Yuko Goto
Bare-Fisted Monk: Unlike the other princesses who wield specialized weapons, Suzushiro fights bare handed. She also has the greatest weapon damage in the cast.
Big Ol' Eyebrows: She has some massive eyebrows that Liliana makes some quips about.
Beware the Nice Ones: She's soft spoken and ladylike, but she's far more powerful than she looks and also quite pragmatic.
Clingy Jealous Girl: She gets pretty upset when she sees Arata and Chris getting along well and even attempts to assassinate him later without a second thought to help Chris. She's also rather rude to the other princesses.
Cute Bruiser: She fights barehanded and, as her synchro effects show, she has very high attack capabilities.
Determinator: She gets beaten around like a rag doll during the Liesel fight, but just tanks all the damage until she finally make that devastating counter.
Glass Cannon: She provides a large weapon damage boost, but she actually decreases your defense.
Hates Being Touched: She has sworn to herself never to allow a man other than Chris to touch her. Arata grabs and pins her when she tries to assassinate him to make her submit.
Honor Before Reason: After she stumbles upon 'Iris' practicing her secret technique she decides to show her own to even the playing field.
Worthy Opponent: She views Iris as a worthy foe and is thus distressed to accidentally see her secret technique.
Yamato Nadeshiko: She seems to be consciously aiming to be one with her domestic and supportive attitude, but she's more irritable than she looks.
Liliana "Lun Lun" Guenther
The Storm Princess of Renstanza, a mighty naval power. She is an Admiral of their Navy. While not the oldest princess of her kingdom, she's the only one who is eligible, which is why she entered the Waltz. She is also motivated by her irritation with her sisters for settling for anything other than a prince when they married. She spends most of her time acting somewhere between silly or downright insane, yet is always perky and cheerful. However, she has the most real combat experience of all the princesses and is incredibly skilled in a ranged-fight.Unfortunately for Liliana, she doesn't get along very well with Chris or her fellow princesses, and she finds herself developing a crush on Arata early on. This causes her a bit of trouble when she actually tries to fight in the Waltz.
Chekhov's Gun: That cellphone call she had from her mother early in the game? About a side job? It's finding an old friend of her mother's, the Queen of Wisley - who turns out to be Fukamori Nanae. She has a conversation with Nanae, passing on a message from her mother and also confirming that Shizuka is the Beast Princess.
Christmas Cake: It's implied from early on that she's quite a bit older than she looks and acts. Her younger sisters are already married. Her actual age is left vague, but it's implied to be significantly older than the other princesses.
The Cuckoolander Was Right: Early on she has a fangirl speculation that the prince and his retainer (Chris and Arata) switched places and that she'd fall in love with the real prince, who is in disguise. Chris isn't Arata's retainer, but Arata is the real prince and Liliana does fall in love with him instead of Chris.
Ditzy Genius: She's genuinely an airhead, but just because she's ditzy doesn't mean she's stupid. In fact, she has the best tactical mind in the group.
Girlish Pigtails: She's the most openly immature of the girls and has the most immature hair style.
Genki Girl: Lilliana is almost always very excitable.
Weak, but Skilled: Her duel with Angela takes undertones of this; while hardly weak, she employs finesse against Angela's power. Ultimately unsuccessful, though Angela notes it was a close match and if she'd seen Iris' Finishing Move first, she might have prevailed over Angela.
Yaoi Fangirl: She mistakenly thinks Chris and Arata are gay early on, but figures that's all right so long as Chris shacks up with her as well.
The Princess of Steel, she hails from Palmeid, a blacksmithing country and the only non-monarchy in Eldhiland. She doesn't really have much interest in marrying Chris—she's really just involved in the Waltz to prove the power of her Dress and for the sake of everyone who helped create it. Liesel employs ruthless tactics and prefers to win by any means possible rather than fighting with honor, and she deeply resents the other princesses for their natural strength of arms. Liesel's personality is intentionally left quite mysterious.
Voiced by: Yuria Hokuto
Badass Normal: No special abilities, no spells, just a skilled blacksmith.
Boobs of Steel: Not that you'd know it based on her appearance, but she's just as racked as Angela. She also carries the story's most destructive weapon, the magitek maul Valfiche.
Split Personality: Of sorts. Her introduction actually features "Liesel" and "Riko" holding a conversation over tactics!
Weak, but Skilled: Has no magical powers or special abilities, unlike the other Princesses; she compensates with her Dress and Combat Pragmatism.
Arata's older sister, who gives him advice throughout the story although she isn't directly involved in the events surrounding the Princess Waltz for most of the game. She's very skilled in kendo and has always practiced with Arata since they were children, meaning that they're very in sync with each other.In the second half of the game, Shizuka takes up a more direct role, though not always prominently. If her route is taken, she is revealed to be the sixth and final Waltz contestant; the Beast Princess of Wisley.
Voiced by: Rina Misaki
Attack! Attack! Attack!: During the majority of the second half of the game Shizuka's strategies are always extremely aggressive due to lacking rationality.
The Berserker: As the Beast Princess, she sacrifices her intellect to tap into her true power. When you finally unlock her route, the seal on her power is removed so that she can fight properly.
Brother-Sister Incest: Arata and Shizuka have been rather attracted to each other for awhile, but with the whole sibling thing it wasn't really an option either was willing to pursue. Since they're revealed to be step-siblings only, the issue is side-stepped.
Cool Big Sis: Very much so. Arata admires her greatly, referring to her as "My invincible sister."
Curb-Stomp Battle: Shizuka is built up as extremely powerful before she's available for use, so rather than give her some sort of arbitrary limitation the story just makes her Purposefully Overpowered and allows you to tear through the final day effortlessly.
Declaration of Protection: Declared she would protect Arata and took up kendo in order to do so. Later has the seal on her power undone so she can actually do so competently.
Divine Parentage: Her father is the God of Fangs, one of three gods that created Eldhiland.
Heroic Bastard: Like the original princess of Palmeid (who is replaced by Liesel), her mother got pregnant before the Waltz began and had to sit the action out. That child was her.
Sixth Ranger: Joining the main cast during the final in her guise as the Beast Princess, she is only identified as Shizuka in her own route.
Sweater Girl: Just one more of her similarities with Angela.
Other story characters
The Princess of the Sword, she is the representative of Soldia in the current Waltz. Initially, little else is known about her. However, she seems to appear whenever Chris is in danger, yet the two are never seen side by side. As the story goes on, it is revealed that Chris takes on the guise of Iris, in order to fight and win the Waltz himself. After Arata and Chris synchronize due to Arata wearing one of Chris' rings, they fight together as Iris against the other princesses in order to fulfill Chris' dream and Arata's destiny.In actuality, the real Princess Iris was the legendary figure who led six other princesses against Shichiou, the demon who threatened to destroy Eldhiland one thousand years ago. After Shichiou's defeat, she founded the Princess Waltz as a means of containing his evil and preserving peace between the countries of Eldhiland.
Angel Unaware: Despite living 1000 years ago, she can still manifest herself in spirit form, appear to Arata in dreams, manifest herself physically within the Imperial Palace of Eldhiland, and yet she hasn't aged a day. She is also able to work with the Powers That Be of Eldhiland to design the Princess Waltz, which requires powers beyond that of a mortal being. Exactly what she is is never really explained.
Big Good: Iris founded the Waltz to keep the Big Bad sealed away. She also assists Arata and Chris in their quest to win the Waltz by lending them her guise, as she is aware of their destiny, the complications surrounding it, and the risks said complications pose to the integrity of Shichiou's imprisonment.
Fighting the Lancer: When Eldhin became a despot, she stepped up from being the Lancer, taking up the mantle of the hero to defeat him and save Eldhiland.
Heroes Prefer Swords: Her signature weapon, and the reason why she is known as the Princess of the Sword.
The Lancer: To Eldhin before his downfall, when he was uniting the nations of Eldhiland in peace.
Sole Survivor: Of the seven princesses that faced the demon Shichiou, she was the only one to survive.
Shichiou is a legendary demon that threatened Eldhiland in its earliest days, who was sealed away by the power of six princesses, one from each country of the land. The sole survivor of the princesses, Princess Iris of Soldia, founded the Princess Waltz to keep him contained. He partially breaks free at the end of the 1st Chapter. His true identity is Eldhin, namesake of Eldhiland, saviour of the land and Princess Iris' former love interest.
Big Bad: He initiates his plan to take over the world as the Waltz starts drawing to a close, forcing everyone to work together.
Disproportionate Retribution: One atrocity that motivated Iris and the other princesses to fight him was the burning down of a castle housing 70,000 soldiers and their families, because they complained about his rule.
Sealed Inside a Person-Shaped Can: Every Emperor of Eldhiland has the soul of Shichiou sealed deep within them when they are born as the Crown Prince. The Waltz is a means of choosing a queen of great power to help keep the seal strong.
Victory Is Boring: He became bored after becoming a successful conqueror and began heavily oppressing the people of Eldhiland.
A mysterious maid who was Chris' tutor. She's rather spacy and hard to read.
Angel Unaware: Her true identity is unclear, but she implies that she's the Goddess of Wings, the equal of the Dragon King and the God of Fangs. Or rather, she says it outright, then says she's kidding and disappears from the story.
Crouching Moron, Hidden Badass: While for the majority of the game she acts like a clumsy maid and tutor, the ending implies that she is one of three god, resurrected people twice, and manipulated quite a bit behind the scenes.
Sexy Mentor: She insists that she's a sexy mentor, at least. Everyone else just sort of puts up with her.
A masked priestess of Eldhiland's Imperial Court, who gives orders and advice to Chris on what to do to win the Waltz. She speaks very strangely and ruthlessly pursues her goal of seeing Chris achieve victory and his dreams of becoming a true prince. She is revealed to be Princess Cecelia of Soldia; biological mother of Chris and younger sister of Empress Lydia; the winner of the previous Waltz, and Arata's biological mother.
Kill and Replace: In order to safeguard the life and ascension of her daughter, Cecelia enlists the aid of then princess of Wisley, Nanae, to kidnap and kill her older sister's child so female-Chris can become the Crown Prince with no one being the wiser. Her plan partially succeeds, as Chris is raised as the Crown Prince and Empress Lydia's son disappears from Eldhiland. However, Nanae does not kill the real Chris Northfield, naming him Arata and raising him as her own son.
Nice Job Breaking It, Hero: Jealous of her sister Lydia (who became the Empress after winning the Waltz), she seduced the Emperor, resulting in the conception of Chris not long after Arata, Empress Lydia's child and rightful Crown Prince, was born. However, because they are both children of the Emperor, and were born at around the same time, they both inherited the Prince's Blessing and the destiny that accompanies it. This sets in motion an imbalance in the system Iris designed, that has kept Shichiou sealed away for a thousand years, as the system relies on there being only one Crown Prince. This imbalance is exploited by Shichiou, allowing him to weaken his seal and escape, through Chris, putting both Eldhiland and Earth in jeopardy.
Redemption Equals Life: In Shizuka's route it is revealed that April saved her life. Nanae tries to push her into being involved in Chris' life in a more wholesome way, rather than in her masked guise.
Your Cheating Heart: Had an affair with the recently deceased Emperor of Eldhiland, who already conceived Arata with her sister, Empress Lydia. This results in the Prince's Blessing being shared by both Chris and Arata, resulting in the main crisis of the story.
Nanae is Arata's adoptive mother as well as his homeroom teacher. She's rather lazy but loves her children dearly.
The Atoner: Was asked by Cecelia to kidnap and kill the original Chris Northfield, but she failed after having a change of heart. She decided to atone by raising him in exile on Earth as her own son, Fukamori Arata.
Divine Date: Had a one night stand with one of the 3 gods of Eldhiland, resulting in Shizuka and her disqualification from the Waltz that Empress Lydia won.
I Was Quite a Looker: Said almost word-for-word by her after Arata reacts with disbelief to her telling him that she's a Princess of Wisley and a candidate for the previous Waltz.
Retired Badass: A former candidate for the Waltz preceding the current one.
Arata's childhood friend who lives down the street and attends the same class in school. Her father runs the kendo dojo where Arata and Shizuka train.
Childhood Friend Romance: She's largely oblivious to how she feels about Arata until he moves to Eldhiland. After that, she's quite depressed that she can't really do much about it anymore until he accidentally leaves the door to Eldhiland open.
Jumped at the Call: In the post-credits Nodoka realizes that she loves Arata in the months after he and the other princesses have left Earth, and regrets not being able to tell him. Cue his short return to his old house on Earth while she is passing by. While she isn't able to convey her feelings to him, Arata, in his haste to return to work in the other world, leaves the portal to Eldhiland ajar. Instead of closing it and walking away, Nodoka follows him through, resolved to win his love just like the other princesses.
Locked Out of the Loop: Even if she meets most of the princesses, she's in the dark about the Waltz and Eldhiland for the entire story until the post-credits.
Oblivious to Love: She has feelings for Arata, but isn't consciously aware of it. When Riko admits she has feeling for him, Nodoka encourages her to pursue them seemingly without a second thought. However, Riko realizes how Nodoka really feels.
