That was a tad unsatisfying. He should have made the shitty nun crawling and begging more before telling her "nope, I don´t handle with assholes".
By the way, where does he keep all his stuff? Is there inventory/loot box magic or does he leave it in a trustworthy inn he found with his guide?
Also, I agree that the Tsunderer is pathetic. Honestly, if she wants to be with him, she should say so instead of asking in such a roundabout way.
