Konosuba: An Explosion on This Wonderful World!, Vol. 2 (light novel)

Lady Aqua, Control Your Followers! With the ultimate offensive magic finally under her belt, Megumin is off to Axel Town to start her adventure, and nothing will stand in her way! ... Except poverty. A trip from the local Teleportation Station isn't cheap, and the closest it can get her to Axel is Arcanletia, the city of water and hot springs. It looks like Megumin's got her (part-time) work cut out for her. Thankfully, she can look forward to help from Yunyun-as well as a certain sect of devout lunatics!
