Welp, she's there for a reason. Personally, I don't mind her not getting any. I think she's gonna be that one person who supports the team wholeheartedly and doesn't pay much mind of the romantic relationship happening as long as they're still on good terms and teamwork. Knowing that Arty is kinda fond of those "literatures" in the guild's library, she will come to an understanding and greater interest, probably. Fujoshi, that's what she's becoming to xixixi.
Nevertheless, let's just see what plans our creator has for her. Cheers!
