Appearance

HeroRio

Rio's Hero Mode

Rio has long dark hair, which she keeps up with two orange strings. She has a variety of outfits she has worn throughout the series. She usually wears a school uniform with a really short mini-skirt, which makes her thong visible at times, especially when she uses her wrestling moves. However, when training she prefers to wear a t-shirt and cut-off shorts with fingerless gloves, and when she went to the Hero Party she was dressed one piece white dress.

Rio has a very small and thin body, which causes many of the characters to look down on her as nothing more than a little kid.  However, her petite appearance belies her true strength and abilities, as she is shown to be one of the most physically powerful characters in the series.

In her Hero Mode of Catgirl Rio, she wears an armored dress/skirt ensemble with a fancy belt, jet pack, wrist gauntlets and stylized boots. She has two robotic cat ears and retractable claws, thereby adding to the cat girl theme. However despite the abilities these give her, she is greatly embarrassed by the outfit and the actions she must do to activate the abilities.

Personality

She greatly believes in the concept of Justice and being a Hero, what she one day wishes to be despite the fact her father initially would not give her a license. She will jump at the call towards any threat she picks up on her communicator or go into a burning building to rescue her friend. Her desire to become a hero stems from the fact that she was unable to do anything when her mother perished in front of her.

Her belief in Justice is so strong, she even shows disgust towards the Hero Association covering up the activities of G9 working with criminals just to protect the Association's image. Though she is happy about finally becoming a Hero, she does not like the fact that she must do silly cat moves and speeches in order to transform and activate her weaponry. However, since she does represent Andou Electronics and is now a Commercial Hero, she is bound to the rules set by her weapons-maker and tactical adviser Andou Hironobu.

History

After watching the explosion which killed her mother, (incidentally it was the same time in which Shuto was greatly injured and rescued by Shiningman), Rio began wanting to be a hero so that others would not suffer the pain of losing loved ones. She would later undergo intense physical training to the point the army was already considering recruiting her despite her age to prepare herself once she became a hero, regardless of the fact that her father refused to grant her a license.

Plot

First Crimes Arc

Rio fell from the sky attacking the three thugs that were ganging up on Shuto Katsuragi. She tells the thug that he can't pick on the weak on her watch. She performs the Frankensteiner to take him down. Another thug recognizes and introduces her. She thanks him for the introduction but thought the thugs were ganging up on Shuto. An angry Rio cracks her knuckles and proceeds to beat the thugs to a pulp for harassing Shuto.  Rio returns Shuto's shoe, which he accidentally kicked at one of the thugs. She says that she bet Shuto threw his shoe at them so he could teach those ashtrays a lesson, and calls him gutsy. Before Shuto could say anything back she stops, because this device she has says that something bad happened at the bus stop.
Rio meeting Ratman

Rio meeting an angry Ratman

After getting home and being informed that her father won't be home till tomorrow, she set her sights on training all night with Billy. However during their training Big Mama interrupted them and dragged her out, voicing how her father wishes for her to stop her dream of being a hero. So after training Rio relaxed in a bath with a drink, until the alarm of an intruder broke into her house. She rushes out of the bath, only to be standing naked before the criminal. She confronts Ratman but, she is distracted by the Jackies trying on her clothes which let Ratman escape. Angry at this, she mercilessly beats up the Jackies before chasing Ratman. It isn't until she realizes that Ratman must be after the Databank, she rushes over just as Ratman shows his anger to Ankaiser which completely terrorizes her. Seeing him as something of a demon, she throws many different artifacts at him in hopes to get rid of him, which provided the distraction needed for a Jacky to release a smoke bomb and escape.
Rio's Nightmare
Because of this encounter she continues to have nightmares where Ratman comes after her

It isn't until later when Shuto was trying to get something to eat due to the side effects of his Append Gear, she offered him a sandwich and they ate at a bench. After Shuto gave her a drink as a thanks, the two got to talking. Rio reveals to him her desire to become a great hero despite her father's refusal to ever give her a license. Shuto however encourages her dream, and reveals his dream to also become a hero. She laughs to this, not at his dream but how they quickly they were able to relate to each other despite it being their second time meeting. It was then that her device revealed a Jacky was spotted in the city and they rushed off.

She gets there just as a Jacky runs by them. Just before anything can happen, a D-Rank hero fires his arm cannon attack at him. While they continue their chase, Rio watches as Shuto jumps straight into traffic to save a cat that went into the street to get a fish the Jacky dropped. Realizing he twisted his ankle, Rio carries him back to school. Despite Shuto being completely embarrassed about his predicament, Rio assures him that what he did just then made him more of a Hero than anyone else. While on patrol she picks up a theft report describing a "tall man in black" and heads to the location and suddenly ran into Ratman. Thinking he was the suspect she attacked him not knowing that Ratman already defeated the real suspect. She continued to attack but Ratman kept dodging until she got tiered. Ratman tried to ask her to calm down and listen to him explain himself but she doesn't and tried to hit him one more time. Ratman catches her wrist and begins to explain as his mouth opens. Rio then yells at him to let her go as well as calling him a pervert and to get away from her. This caught the attention of two civilians who ran to call the cops, Ratman then lets her go and she collapse.

Van Guardner reluctantly concedes and tells her to be careful in search for her friend.

During her search she felt a tremor and complained about the smoke blocking her view. She then thought she saw Shuto only it turns out to be the Jackies carrying Prismman. Not knowing what was going on she asked the Jackies if they were the ones who started the fire but Ruby Red tells her that it was them (Prisimman) who did it from their infighting and it was Ratman who tried to stop them. Regretting their actions the said they did not deserve to be heroes. Just then an explosion occurred and Ruby Red pushed a Jacky to safety and fell and grabbed a ledge. The ledge gave way but Rio grabbed him before he fell. Ruby Red tells her that he is too heavy and she should let go or else she will fall too and it does not matter since he will lose his license. She then yelled at him that he does not know that and at least for now he is still a hero and not to be upset and that there were some people who dream of becoming heroes but can't.

She shows off her skills by defeating an empowered low-ranking hero who had gone berserk after receiving the Hero Booster. During her first outing as a Hero. she seems to gain some fans due to the catgirl theme, (especially from Kanta Matsui), though she feels humiliated over the issue of having to announce her Hero Name.

They eat lunch together. Rio invited Shuto and Kanta Matsui to the party for the heroes. Later on, she saves him from some bullies and gave him a pep talk on never giving up, (which incidentally made him decide to continue as Ratman).

Ratman

Ratmanandrio

Ratman & Rio fighting side-by-side

She was greatly terrified of him, constantly having nightmares of when he first showed his teeth towards Ankaiser, However she became dedicated to one day bring him down herself. She later seems to have mixed feelings for him after hearing how Ratman stopped Ruby Red during their fight, admitting she can't figure him out. Although, after he helped her reach the scene of an incident to help the victims of a car crash she seems to see him in a different light. In later chapters she seems to show hostility towards him, but can now fight along side him without fear or believing he is somehow involved in the criminal activity, showing she now trusts him to a degree. Her encounter with Ratman in Chapter 35 shows that she's willing to accept help from him in a fight.

After the Hero Booster Arc, she actually helps Shuto/Ratman break into the secret room at her mansion to learn the truth about Shiningman and the S Gene, showing she now trusts him.

Andou Hironobu

Rio's father hired him to design and build her weapons and equipment, as well as be her technical and tactical support.Since his new company is now her sponsor, Rio has the embarrassing duty to announce herself as Catgirl Rio, representative of Andou Electronics.

Yavais

Rio considers him as a glory-hungry idiot, though she does respect him for wanting to help others like a real hero.

Trivia

  • Though she does represent Andou Electronics, she's most likely directly sponsored by the Hero Association, due to her father being the president.
  • Rio becomes the fourth hero to find out about Shuto's identity as Ratman.
