Emi, Maou and Alas = Ramus are out shopping together. Maou went to see what was in another department, so Emi and her daughter were left alone. Emi is holding the little girl in her arms. And then some man comes up to them and after a while he starts asking non-comfortable questions. It was a normal conversation at first, but then it got intrusive. Alas=Ramus and her Mom are not comfortable anymore. Emi is usually calm with other people, plus they're at the store now and she has a baby in her arms, so she can't do much. Just kidding, Emi got angry and was about to draw her sword when Maou showed up and as if nothing had happened, he took Emi's hand (which she was just about to have the sword in) and started to lead her to this other section saying "I found the perfect clothes for our daughter, Honey". And although his expression was nonchalant, there was a chill in his voice and a clear message to the person who spoke to Emi.
The man with fear in his eyes decided to go to another shop and Emi decided to follow Maou saying nothing. And although she didn't say anything aloud, she didn't pull her hand away. She squeezed his hand gently in a gesture of thanks, and Alas-Ramus shouted "Daddy our hewo!!"
