Rishia Ivyred

Rishia first appears near the end of volume 4 during the final companion exchange with Itsuki. She belongs to the house Ivy Red, a fallen noble family, according to the queen. She is describe as very child-like by Naofumi and seems to lack a definitive role in her group of companions. She plays the roles CQC, Attack Magic, Healing, and Support. In chapter 109 of the web novel Rishia is accused of breaking Itsuki's bracelet he got from the Swindling Merchant which deeply upsets her. Everyone in the party including Itsuki shuns her out of the party to which she responds by trying to commit suicide only to have Firo save her. Naofumi is outraged that she is being falsely accused and asks her to join his party in order to become stronger. She hesitantly does so for Itsuki's sake. She is level 68 when she joins the party so in order to compensate for her lower level she is asked to wear the Penguin Plush. Naofumi asks her to consider being a slave for the sake of his Slave Growth Correction ability. He also learned of a way to reset her level/stats/class up choice from the queen to which he also offered to do for her. After considering it heavily, she decides to trust him and become a slave. Soon after accepting, a High-class slave crest was engraved on Rishia’s chest. Just like Bitch, after a while it turned invisible. After checking her stats Naofumi noted that although she was level 68 her stats where nearly 1/5 of Raphtalia's.

Slave curse is applied. c1--

Naofumi calls her out on her "Fuuueeee" shit. c1--

Hourglass stops and wave is pushed back 3 1/2 months. Time to return to level 1. Her stats barely decrease though.

She levels with Firo. She's like level 20ish I think c1--

She's left in charge of the the village’s management and level raising while Naofumi is away pedaling. c139

She is up to level 35 but Naofumi wants her to class up with the others so he says she might have to wait for the others to catch up. c140

Rishia reaches level 40 and is able to class up. Naofumi informs her and the rest of the slaves of the way Raphtalia and Firo classed up and explained that they didn't have a choice in which direction their class up too them, but since they gained stats superior in all fields to most other class ups so it all worked out in the end. He then asked if she would like to do the same at the cost of her choice in direction of the class up to which she declined. c144

She classes up into a "Universal" type as contrasted to her previous choice that focused on close combat with the hopes of becoming part of Kawasumi Itsuki's meat shield rather than directly assisting him. All of her stats grew higher, but not that high in comparison to Raphtalia and Firo's that nearly doubled everything with the help of Firo's ahoge. c145
