I get what you meant by that, but everyone besides her was an NPC in the game anyway. Some were just more important than others. Mob character might've been more to the tune of what you wanted to say.
Lmao @ all these butthurt comments calling Iris a thot cause she didn't go for Kururi. You realize Kururi doesn't see her in a romantic light either, right? But oh no, not a platonic boy/girl relationship in my isekai fantasy! Seriously, grow up.
