She was a small-time adventurer who joined briefly to Motoyasu's party and was enslaved and sold by Bitch. Later she was freed by queen Mirella and joined a unit of spies that worked under her ordes.

Appearance
Rino is a pretty young girl in her around his twenties with a medium build, being around the stature of Malty. She posses a long curly golden hair along and ahoge and blue eyes.

Personality
Rino is a nice but entirely too trusting and enthusiastic girl, when the Spear Hero, Motoyasu, flirted with her she responded enthusiastically and was even more enthralled when he revealed his identity. She ultimately took up his invitation to join his party.

Compared to Malty and the other two girls, Rino actually was quite shocked by their attitudes and couldn't quite understand why they acted the way they did, such as cheering Motoyasu on instead of helping him fight. She also was entirely too gullible and was easily tricked by Malty's lot and sold as a slave.

After being released from slavery, she developed a thirst for revenge and pleasure in tormenting her enemies just like Naofumi's. Nevertheless, she still retains her basic personality and have a great deal of insight and autocontrol, being able to wait for the right moment to enact her revenge and help his allies.

Background
Rino was a small-time adventurer in Melromarc and one of the many, many women Motoyasu flirted with and invited into his party, she accepted this invitation, which ultimately decided her fate.

Volume 1
Rino joins Motoyasu's party after he flirts with and invites her, however, she is quickly shocked by the other girl's disposition, as in they'd rather be Motoyasu's cheerleaders than his comrades. Finally, Malty tricked her and sold her to a slave shop at the end of the day and told Motoyasu that Rino left because she felt that she didn't fit in.

Sometime later as Motoyasu is walking through an alleyway he hears her voice but fails to accept it due to his delusions preventing him from noticing things that would be bad for his image of his surroundings (refusing to believe his comrades would've sold her as a slave), even when she calls out for help Motoyasu simply assumes it's a professional prostitute acting out someone's fantasy because of the sounds coming from the room and the nature of the shop it's coming from. Her fate after which remained unknown.

Volume 19
Rino is revealed to be the spy of Melromarc's that followed Bitch across the worlds At some point after her return and meeting Naofumi, queen Mirella searched and aided at the victims of her daughter, Rino among them, who was freed from the brothel. Later, Rino and other victims of the former princess were given the opportunity to join the ranks of the spies of the country and after the incident with the spirit turtle and the escape of Bitch, she and the other victims formed a special unit to hunt their hated enemy under the promise that Bitch will pay for all that she did. After Tact defeat Rino was able to catch the trait of Bitch and witness when she and her allies crossed worlds, then, she decided to follow them and fastly left behind information for their comrades.

Trivia

 * She also helps allude to the possible fates of the men and other women who "didn't fit in" with Motoyasu's party according to Malty, with her own fate serving to imply that they're either dead or worse if they did not choose to willfully leave the party before Malty simply got rid of them.
