Younger brother of Krichevskoy, and Laharl's uncle. Despite his muscular physique, he talks like a woman and doesn't have the guts to stand up to his own wife. He wears a radiantly colored pink mantle that if you see it once, you'll never forget it. Was once in love with Sakura, but he was turned down.
Too Kinky to Torture: He shouts flirtatious and excited compliments when he is exposed to pain. It made Flonne so uncomfortable that she let him go once she caught him.
Porn Stache: What it lacks in thickness it makes up in length..
Unusual Eyebrows: They are long and serve as his antennaes, the family trademark.
Vesuvius’s wife, and Laharl's aunt. Back in the day, after Laharl’s mother died, she "took care" of him for a 100 years, and she abused him with her whip. Since then Laharl has hated women with sexy bodies. She is not fond of Laharl being the Overlord because he has human blood running through his veins.
Fantastic Racism/Politically Incorrect Villain: Believes that humans are lower than dirt and proceeds to abuse and "discipline" Laharl when he was younger because of him being half-human.
Fetish: She really enjoys abusing people with her whip, even teenage girls.
Hair Antennae: She has them, even though she is not directly related to Laharl.
Horny Devils: Not confirmed, but her strong resemblance to the succubus class indicates it.
Mama Bear: She defends Shas and Kira from Sakura in one book, picture here◊. Might also double as Pet the Dog considering who it is doing such a nice thing.
Vesuvius and Yasurl's daughter and the younger twin sister of Kira. A rather young demon. Used to share her body with Kira, but he tried to take over her body, so she rejected him. She now “plays” with Laharl a lot, setting up traps to destroy him. She's a tad-bit crazy and is one of Laharl's problems.
Token Mini-Moe: Even though almost every girl in Laharl's harem seem to be physically teenage girls, she's the youngest in appearance. She seems quite fond of him and shows it in her own deadly way.
Vesuvius and Yasurl’s son and the older twin brother of Shas. He's actually a ghost and can take control of Shas's body. Has a sick mind and tried to trick Flonne and Etna; and took hostage of Shas’s body to try to defeat Laharl. In the end, he was purified by Flonne and was sentenced to be a prinny for 100,000 years for assassination attempt to the Overlord. He is currently spending time in Celestia to repent.
Tropes associated with Kira:
Child Mage: He uses magic as his primary method of attack.
Divide and Conquer: Kira tries to set Etna and Flonne up agains each other by telling each of them that they would make a perfect girlfriend for Laharl, taking advantage of the crush each harbour for Laharl and distracting them from the plan of taking Laharl off the throne.
Daughter of Captain Gordon, Defender of Earth! and Jennifer. She can identify the difference between Shas and Kira (who is a ghost). She has been fond of Laharl ever since he saved her from Kira.
Smitten Teenage Girl: Her crush on Laharl is unnaturally intense considering he is a irritable and disagreeable young demon who does not appreciate the attention he gets from her at all.
Flonne's younger sister. Rare kind of angel: she likes money more than love and is the exact opposite of Flonne. She ran away from home. She is fond of Laharl since he's the Overlord, and she is always arguing with Flonne. She came to the Netherworld as an exchange student, but went back to Celestia to become a woman worthy of Laharl.
Hair Decorations: The bandanna curled on the top of her head. Subverted as it is most likely not meant to make her look cuter, but more male-ish since its shape is reminiscent of hats some male angels wear, like her father.
You're the Overlord? You're tinier than I thought.
Friendless Background: Her "alternative" beliefs has most likely not earned her many friends, if any, in the world of Celestia. She grows quickly attached to Laharl, who might have been the first person she had ever met that have similar beliefs to that of her own.
First Name Basis: Overlord Laharl gives Ozonne special permission to call him just Laharl because they immediately hit it off so well.
Good Is Not Nice: She is a good person with the best of intentions for the people angels have vowed to protect, yet really unpleasant to be around unless you are of the same perception as her.
Green-Eyed Monster: She is envious of Flonne in many ways. Flonne's status as a fallen angel is one of them.
Grumpy Bear: Milder version, but not if compared to other Celestians.
The Heretic: She propagates beliefs that go against Celestia's official dogma and is considered to be a heretic, but she is not excommunicated for it because Seraph Lamington wants to let heretics run free.
I get goosebumps just from thinking that I'm related to them by blood.
Informed Attribute: The narrator claims Ozonne is slightly better endowed than Flonne. The artwork does not back this up.
Lady Looks Like a Dude: According to the narrator, the only thing that distinguishes her from completely resembling a male is the very very slight curve of her breasts.
Trans Nature: Ozonne wants to become a demon (more precisely a fallen angel) because she does not fit in with the other Celestians and so she can be with Laharl, in fact she thinks marrying Laharl will cause her to become a fallen angel.
Tsundere: Towards Laharl. She's notably even harsher than usual when talking to Flonne.
Tsurime Eyes: Laharl notes that her eyes are a bit like Flonne's eyes when she's angry, but even more vindictive.
Flonne and Ozonne's parents. Father Terre is always refreshed, and mother Elle is always smiling. Even bigger "Warriors of Love" than Flonne. "LOVE" is their family motto. They made an oath with Laharl to make sure he stays friendly with Flonne forever.
Tropes associated with Terre and Elle:
Angelic Beauties: It is easy to see where Flonne gets her good looks from.
Hair Decorations: Elle's flower hairpin suits her surprisingly well for her age.
Love Freaks: Their entire home is filled with objects that express their worship of everything that has to do with love. They are the parents of the original love freak, after all. Laharl visits them in the third novel. Hilarity Ensues.
A woman looking for rare and legendary swords. She's female, but she likes flat-chested girls. She wears a traditional Japanese Kimono. She carries a Masamune she created out of Caliburn, and she's a Master Swords-woman. She can't use magic but she can use a couple-hundred swords at the same time. She is on a journey to find both Caliburn and Excalibur, because she burns with passion as a 'Sword Maniac'. Her power is equal to that of Laharl, and her life is divided between several other archangels. She has once beaten Laharl. She was once an archangel working under Lamington, but since angels change between male and female depending on the situation, after becoming a Sword Master her male-side dominated her heart. But after she lost to Laharl, her female-side took over, she fell in love with Laharl and now she stays at the Overlord's castle.
Wife of the King who ruled the human world about a thousand years ago. Laharl met her when he and Flonne travelled back in time. He became very fond of her since he was aware that she's in fact his mother. After Sakura came to steal the King's Excalibur, she and Gwen went to the future world of the Netherworld. She became Sakura's servant, but she escapedand met Krichevskoy, married, and had Laharl.
Tropes associated with Gwen:
Action Girl: She fought alongside her first husband and his army in battles.
Alternate Continuity: In the novels, she was originally the wife of King Arthur. In the games, she was a witch who came to study in the Netherworld.
The Archer: She uses a bow and arrow for long distant combat.
Brainy Brunette: She never gets a chance to show how intelligent she is, but in the game she was a witch and in Disgaea intelligence is the statistics that determines how powerful a character's magic is, making brains a requirement to be a good witch.
Good Parents: To her son, Laharl. She loved him more then anything else and raised him to be a good boy. Then she had to sacrifice herself so save him from a incurable disease. It broke his heart.
Man of Steel, Woman of Kleenex: She ended up marrying Overlord Krichevskoy, who was so powerful that he could knock down mountains, freeze oceans and split the ground in two. How they managed to make Laharl is a mystery.
Mayfly December Romance: She married a demon Overlord who most likely was several thousand year old at the time, when she looked no older then 20.
Modest Royalty: Both of the outfits she is seen in are modest and simple (by Disgaea standards that is).
Proper Lady: Possesses almost all of the characteristics; gentle, strong, virtuous, sacrificing, wise, loving, caring, tasteful, civilized, mannerly, devoted and loyal. Not to mention British. The only exception is that she does not require protection.
Sexless Marriage: It's not stated directly, but Flonne mentioned that she does not feel any love between Gwen and her first husband, despite Gwen's fierce loyalty. Her second marriage fared better though.
Undying Loyalty: Towards her first husband. She fought loyally by his side in combat and stated that she would not want to live without him. Thank god she got over it, because she had a Physical God to marry and child to bear.
