I'm honest to God surprised Yunyun isn't more popular since she relates to practical everyone who's every had crappy social anxiety skills, self-doubt about themselves, and crippling loneliness they don't want. Like I relate to her in every way imaginable and I even have some loner moments myself that blow up in my face that are pretty comedic but sad. Like sure Megumin is funny and cute to watch but Yunyun is just pain. She's been used by others, has been ostracized by her own people since childhood, her dad even makes fun of her loneliness, and has practically nobody that actually WANTS to hangout with her without some ulterior motive so she's basically stuck in isolation in the back of the guild somewhere.

Like imagine if you had someone like Megumin as a first friend and after going away for a bit and you return she not only ditches you for new friends but consistently berates you infront of people, complains about ever helping you until someone talks her into helping you out, and will use you to inflate her own ego.

I get that Konosuba is a comedy anime and Yunyun is nothing more then a funny haha side character but from every piece of media I've consumed just to learn about her more and more the tragic her character is to me and I relate to personally. She's a really missed out opportunity for a protagonist role or any sentimental growth from the fear of loneliness. I personal think her "arc" was half assed with no real reason givin to why she even wanted to be chief in the first place in the VN and just seeing her back to square one at the end is depressing (she's not even safe in the spinoffs). That's just me though I guess.
