I like Emi better.
tfw no more regular Maou threads
Seconded, I felt like the anime didn't spend enough time between Maou and Emi.
It did handle the interactions better than the manga at least. It was too cliche and left not much to allude to.
Emi is cool, but personally, I like Suzu more. I admit Emi is a better character and is more suited to be paired with Maou though.
