Ancestral Weapon: Because Clarissa is actually Alexia Elesius, Strahl Gewehr is her ancestral weapon and is traditionally used as part of the ritual in talking to the Guardians.
Expository Hairstyle Change: Clarissa's first hair and outfit change reflect her willingness to live the lie in order to save the people of Elesius. She changes it again once when she travels back in time and meets her deceased mother again.
Switched at Birth: With Alexia, although not actually "at birth". The real Clarissa was wearing an imitation of the princess's dress, and both were caught under the same falling rubble. The two girls were mixed up when rescued.
Took A Levelin Badass: Both throughout the game and again in the manga by just looking at her "11 years after" look.
You Killed My Mother: Clarissa's motivation for chasing Rupert into Elesius is initially implied to her trying to get her mother's sword back. It's later revealed that Rupert murdered Melissa before stealing Iskender Bey, and tricked Clarissa into helping him do it, explaining why she hates lies so much.
Clarissa's adopted brother with a Mysterious Past. He seeks to protect Clarissa no matter the cost.
Badass Longcoat: Unusually for this trope, it's buckled up rather than left open. It's still badass, though.
Switched at Birth: With Clarissa, although not actually "at birth". She was wearing an imitation of the real Princess Alexia's dress, and both were caught under the same falling rubble. The two girls were mixed up when rescued.
Former tutor to Alexia and other noble children and court magician. She is on the run from the Council when she mistakes Clarissa for Princess Alexia. She lacks humility, has a weird fascination with Clarissa's costumes, and is defensive about the fact that she's 34 years old.
Competence Zone: Laby is twice Clarissa's age and has insecurities to match, since, after all, one is far into one's decline by the mid-thirties.
Doppelgänger Attack: She can create a clone of herself as a distraction or to help solve puzzles.
The Red Mage: As an Arcanist, she has both offensive and healing magic.
Teleport Spam: The best use of her Warp ability, which is unique to her.
A reckless, idealistic and loud young man who has a crush on both Alexia and Clarissa. His father, the head of the Praetorian Guard, disowned him when he ran away to join the princess' rebellion (though more because Captain Eisen works side-by-side with the villains than because he thinks Levin's wrong).
Squishy Wizard / Fragile Speedster: His magic stats aren't that great and his defense is terrrible, but his base class's movement, reflex, and climb are some of the best in the game. He even has an attack that's damage is based on the difference between his and his target's reflex score.
A Drifter whose home and family were destroyed by Elesius' constant wars of conquest. He came to the country looking to destroy it, but over time changes his goals to destroying the old regime and building something better.
Lightning Bruiser: Other than his ability with magic, which is pretty weak, he's pretty much the strongest character on the team with higher ATK, DEF, MOV, CLM and RFX than most of the others in the party (except those who excel at those stats), his base class also has better all-around attack range than most of the classes (Clarissa can shoot further, but Ragnar loses no attack strength for his distance).
Not So Different: How he sees himself with the Zortroa Kinship and Chelle specifically. It makes it easier for him to relate to their problems and talk to them about changing their minds.
God Was My Co-Pilot: Tony is revealed to be Luceid, the Guardian of Desire. Only the player realizes this, though.
Spoony Bard: Tony's inability to change character class and lack of native skills means he becomes less and less useful as the game goes on. By mid-game, the player will probably have replaced him on their team with a Player Mook.
A ruthless Drifter who will do anything and kill anyone to get what he wants. He killed Melissa Arwin in front of both Clarissa and Felius and stole Iskender Bey. He is currently in the employ of the kingdom of Elesius.
Also known as the "Death Merchant", Weisheit is an arms dealer who has a long-standing relationship with the monarchy of Elesius. He's actually Kressen, one of the heroes of Elw Borea who later went rogue and had to be imprisoned. He's seeking revenge against Felius and a way back to Elw Borea so he can conquer it (or, failing that, destroy it).
Ambiguous Gender: Rupert even comments on it. In reality, "he" is a male consciousness (Kressen) possessing a female body.
Grand Theft Me: How he survived so long, and what he plans to do to Felius.
The chairmen of the Council of Elder Statesmen, which makes him the unofficial ruler of Elesius while the king is bedridden and his only heir has not passed the trial to make her eligible to rule. He wishes to restore the kingdom to what it was before: an aggressive, expansionist empire.
The king of the kingdom of Elesius, once a renowned warrior. He is now bedridden due to infirmity. It is his dream to change the war-like and expansionist kingdom he inherited to a peaceful one, but his reforms have been very unpopular.
Heroic Sacrifice: In order to save his daughter, the rebellion, and half the capital city, he sacrifices his own life.
Hot Blood: Even when weakened from illness, he charges Asgard, shattering the normally unbreakable barrier with a single punch which leads to his Heroic Sacrifice.
