“ | What makes someone strong is not just the brute strength of their fists thrown to the one they hate, being strong is more than that! the will, the intense and human emotion of deep longing for achieve something is what keeps you going! This is why I am fighting, no matter how weak I feel, I will keep fighting for the ones I care for! | ” |
— Iva.
Ivanna (イヴァナ, ivu-ana, viz: Ivana), also known for her hero alias Ladybug of Chaos (カオス・てんとう虫, Kaosu Tentōmushi, viz: Chaotic Ladybug) she's the C-Class Rank 84 (previous the Monster Association events she was at Rank 91) professional hero of the Hero Association. Ivanna is a college Law student and a beginner martial artist that used to train on the Sunflower Dojo's Gentle Self Defense owned by Hamukichi under the recommendation of her parents, though she left the dojo in an attempt to keep polishing her abilities beyond the self-defense and in an act of independence, started as a hero. She's commonly referred as “Iva” rather than her full name, a preference she had since her childhood. She is very disorganized in her fights and that's how her hero alias was formed, adding to her fascination with flowers and the polka dot patterns in her left legwarmer and helmet. Currently she trains at Bang's Dojo next to Charanko, Sour Face and Garou.
Iva is an average, nearly thin young woman with a long, slightly wavy, waist-length chocolate brown hair and micro-bangs, which is usually styled with her hair with loose hair, and almond shaped dark brown eyes. She uses rose velvet lipstick on most occasions, which becomes most noticeable in her appearances with Garou. Her attire tends to vary through the manga (this mainly because her hero duties are not that present in her daily life) but there's one that she uses more frequently, this one being a fitted short sleeved red shirt with a turtleneck with a long black skirt or, in any case, with a short dark gray pleated mini skirt, with black stockings underneath and red slippers that she also uses for her hero attire, or red low heels. The look her hair has also varies from the loose previously mentioned to being tied into a bun or a braid, and on very rare occasions a ponytail. Also, in her childhood flashback and shared memories with garou, she was showed with a bob cut and longer bangs.
Her hero attire is based on a ladybug, which is also one of the reasons for her hero alias. Iva has a very characteristic helmet, this one being based on a ladybug, red and with medium sized black dots over all over it and a pair of antennas, the right one a daisy hangs from the end of it. The upper part of the outfit is composed of a black short sleeved with a turtle neck bodysuit, on top of it a short and loose white top which sleeves hang a bit over her right shoulder, the inferior part of her outfit unequal-length stockings on the lower part, on the right leg reaching up to the thigh, which has red dots printed on them, the one on the left side reaches below the knee and does not have the aforementioned dots; she also has loose-fitting black leg warmers, which have the same dynamic of a single leg warmer having a polka dot pattern, only in this case it is the left leg that has them, and for her shoes she uses her characteristic red slippers. She also wears ladybug earings at the beginning of the manga, those were destroyed in Monster Association Arc.

Iva's hero costume
Iva was introduced as a low rank hero who showed herself as a naive, impulsive, overly emotional and stubborn woman. This cheerful and overexcited behavior has been present since her the first meeting (which is also her first appearance) with Saitama, Genos and Bang at the Hero Association lobby before the Alien conquerors, where without a second of thought she excitedly shows respect and admiration towards the S-Class Hero Rank 3 (at the time) “Silver Fang” (Bang) by sharing to him how she always looked forward to watching a demonstration of his technique “Water Stream Rock Smashing Fist” on TV since she was fourteen, she realizes that she was embarrassing herself when the S-Class Hero Rank 16 (at the time) “Demon Cyborg” Genos decided to comment about how Saitama and Bang were in a hurry for an important meeting, which made her feel immediately ashamed, leading her to apologize and look down at the floor.
Even if she willingly joined the Hero Association structure by being a hero, it was an act of impulsiveness and a way to reassure and prove herself about her parent's views and doubts about how clumsy she was to handle herself alone, though in many occasions she seems to lack of courage and is unable to say no to her parents' wishes, showing a bit of the fearful and people pleasant position she actually is and unintentionally hides under the stubbornness, intensity of her emotions and morals. Part of Iva morals is based on the genuine despise, hate and resentment to “dirty intentioned” selfishness, this hatred built up due to her personal experiences with people that manipulated situations however they wanted thanks to having the power to do it and the intention to hurt someone else, making the vulnerable and less privileged one be on a bad spotlight, which often resulted in being hated by said powerful figures. The “dirty intentioned selfishness” comes out from her soft self on people, coming out as empathic with the people that surrounds her, which makes her belief in selfishness to separate based on the way people behave and tries to look out for the reasons behind everyone's actions, making her believe that sometimes being selfish is acceptable when you are not doing it with the exclusive purpose of hurt someone and stand up for yourself, said thoughts is one of the aspects she admired of Garou and the least she applied on herself because of the already mentioned people pleaser attitude she unconsciously shows for the sake of not hurting others, exposing her as selfless in front of some people's eyes, especially Garou, who has shown frustration, perhaps irritation towards her at times. Her presence in the Hero Association has been slightly uncomfortable over the brushes she has had with some executives and some heroes among her class, who seem to bother her with a constant double standard or facades of being the perfect and innocent people who only look the good, just like Red Nose and his attention-seeking and selfish personality, who she has had multiple discussions with thanks to being teamed with him various times.
Though Iva's cheerful and impulsive self, in her hero's duties she doesn't enjoy being in the spotlight, showing that she's actually introverted outside the people she admires and/or is comfortable with. Whenever the crowd is more than the people who are being helped out by her, she tends to get clumsier movements and seems a bit unable to explain her mind, being a lower Rank is still a way to be far from people's eyes and avoid a fanbase because she herself thinks she wouldn't be able to handle to be perceived by many people at the same time, this introversion is also shown in how she works, tending to do quiet duties like cat rescues, some criminals and community service while avoiding the made-up teams by the association that has received multiple letter of request from her has asking to not consider her as often as others for them, though she tries to be as cooperative and useful as possible whenever they put her into one. In battle she feels a bit more secure of herself, especially if the opponent she's fighting against is a monster which results in her personality getting blunter and more playful thanks to the adrenaline rush, she gets from them, adding to the mockery towards the weaker monsters who often end up underestimating her spirit. She is compromised to get better at fighting and being strong, her caring nature blooming with the intention to protect the weak and the ones she loves and cares about, this boosted by Garou's presence and impact in her life, which pushed her further to test her abilities between fights when there's no danger for any civilians, using battles against monsters as a way to prove how better her resistance has gotten since the last monster she fought and learn from them.
Despite having her sassy, impulsive and overemotional moments, Iva on multiple occasions have shown that she's actually pretty clumsy in her social steps, missing social clues and not having a good survival skills (that are often missed for her will to help), which goes against her instincts on various occasions and getting her into trouble, this can be seen when though her body was sending warning signals about the near danger and blood thirst coming from Royal Ripper, she still assumed it was a civilian or a simple criminal that wanted to harm the Tareo, concluding in her get into a “battle”, losing and get captured as well after spitting that she knew about the Hero Hunter Garou and seem concerned about him. This event also is a hint towards Iva caring nature and how she puts others before herself no matter who they are, like how even if she didn't know Tareo or if the silhouettes (Royal Ripper & Bug God) were his parents, she still tried to make sure and protect the kid and ask for Garou's wellbeing before anything else and later by waking up and asking for the kid before where she was at.
On several occasions Iva shows deep admiration and love towards Garou. Through the Human Monster Saga, the affection she felt towards him was ambiguous if the love was romantic or friendly, her emotions flooded whenever he was in conversation or near him. In the ominous future Cosmic Fear Garou created, her last feelings and thoughts are focused solely on him and how sad it made her that such a golden heart was darkened by something else, confessing how she would've loved to lean her head on his shoulder once again and how she wished to have been able to help her only and most beloved friend. Before the Hero Hunter Arc she confesses how she felt somewhat safe near him and at the end of his saga she doesn't hesitate to support and care for him, proving her caring nature, especially towards him.
Though all her overemotional scenes are mainly focused on positive aspects of her life, Iva has a very rigid way of thinking and behaving, which makes her have trouble in her mood and self-perception, she often suggests how studying law is the only thing she was made for though she doesn't enjoy it, her instability built up in the starts of her relationship with Garou, where he caught her self-harming habits. Her rigid rules make her look for ways to control herself through self-harm and her eating habits, also making her fall in categorize her actions in good or bad things, making her believe that she is in reality a selfish person for not considering how the ones surrounding her feel over her mental state adding to her self-destructive self. She managed to see further the black and white after the night Garou found her in her apartment turned into a mess, she trusted him and asked him to stay, letting go of the grip on the fear that didn't let her live.
