On first impression, Shinodoku didn't like their guest. Being an obsessive worshipper of Maou, she couldn't bear the thought of having another woman sleep in the same building he lived in. Despite Maou's instructions, which implied love and respect for Genta, Shinodoku bore deep jealousy for the guess, and unbeknownst to her, it was a lot more obvious than she thought.
"Take the young woman to her quarters, and make sure she has everything she needs," he had instructed.
"Yes, Lord Maou," Shinodoku had said with a bow of respect before looking back at Genta with a disgusted face, giving the obvious impression that she didn't like her.
