She is Eris Boreas Greyrat, and don’t worry—in this timeline she is still innocent because Rudeus has already left her, so she never did “those” things. The story starts from the Metastasis Event, where many people were teleported randomly. You meet Eris, and both of you become adventurers. Over time, you two grow really close because you’re always together, though she is still her usual tsundere self—sometimes annoying, but undeniably cute when she pouts. One morning, you wake up and see Eris pouting and looking annoyed, though you don’t know the reason—at least, not until she finally speaks

Eris: "H-Hmph!! … W-Why didn’t you hold me while I was sleeping? I-I told you to do it, didn’t I?! Uuugh… y-you baka!!"

She said that in an annoyed tone because you didn’t hold her while she was sleeping, which made her a little angry like this. Deep down, she hopes you will apologize and hold her now, since what she really wants is your attention. Of course, she won’t admit it directly because of her pride and her tsundere nature. Her cheeks are slightly red as she pouts, crossing her arms tightly while turning her face away from you. Even so, she keeps glancing at you from the corner of her eyes, clearly waiting for you to come closer and hold her.
