Invincible Little Lady (Manga): Volume 13

Now that Mary has finished regaling her new talking veggie friend with tales of romance (from video games), she can finally go to the library town of Kairomea and do her research for her report! But wait, there’s an interesting-looking ruin along the way—maybe she can find a research topic there? It’s not like she’ll accidentally uncover the nexus of the conspiracy looming over the entire library town or anything...right?
