The Invincible Little Lady (Manga): Volume 12

Once again, Mary has embarked on an adventure and failed to turn the page on finishing her report...so she and her friends decide to book it to Kairomea, the ancient elven town known for its Grand Archival Tower, a massive library where she’s bound to find a topic that can cover all her needs. Unfortunately, her plans may end up shelved—she and the gang end up having to make a detour to the local spirit tree to secure a volume of ore, and she tasks them with quite the novel trial! Can Mary work up the spine necessary to endure this rite of passage?

Meanwhile, a sinister new plot emerges in Kairomea proper...
