High five! Honestly they are better than guren and mahiru. I hope on the original owari no seraph. They would end up as a couple ε=ε=(ノ≧∇≦)ノ
i guess shinya has a some kind of crush on guren, as you can see in the chapter 83
Guren and Shinya really have the best chemistry, and if I had to go choose a straight ship with him, I would go with the red haired girl. She looks much more interesting than Mahiro.
